Cardiovascular Procedures in Emerging Markets

Cardiovascular procedures are high volume, big business in the well developed U.S, European, and Asia/Pacific markets. But much potential procedure volume has been tapped in these markets, with any appreciable growth limited to low volume, emerging procedures.

By comparison, the less-tapped emerging markets, “Rest of World” potential (i.e., non-U.S., non-Europe, non-Asia/Pacific) for growth is significant. Below is illustrated the 2016 size and growth to 2022 for the major cardiovascular procedures in the Rest of World.

Wounds looking for closure: Untapped potential for sealants, glues, hemostats

Today’s surgeon has a broad range of products from which to choose for closing and sealing wounds. These include sutures, stapling devices, vascular clips, ligatures, and thermal devices, as well as a wide range of topical hemostats, surgical sealants and glues.

However, surgeons still primarily use sutures for wound closure and securement—sutures are cheap, familiar and work most of the time. Now, in addition to reaching for a stapling device, the surgeon must frequently decide at what point to augment or replace the commonly used items in favor of other products, which product is best for what procedure or condition, how much to use, and ease of use in order to achieve optimal patient outcomes. Because of budget pressures, the surgeon must also consider price when selecting a product. Of course in the USA, the product must also be FDA-approved, although the surgeon still has the choice of using a product off-label.

In the areas of sealants, hemostats and glues, there is room for both improvement and additional products.  There are a number of products already on the market, but the fact is that there is no one product that meets all needs in all situations and procedures. There are few products that stand out from the rest, apart, perhaps, from DermaBond® and BioGlue®. There are unmet needs, and companies having the necessary technology, or which may acquire and further develop the technology, can enter this market and launch novel items. These products have yet to significantly tap the potential for wound management and medical/surgical procedures.

Sealants, Fibrin and Others

Numerous variants of fibrin sealant exist, including autologous products. “Other” sealants refers to thrombin, collagen & gelatin-based sealants.

Fibrin sealants are used in the US in a wide array of applications; they are used the most in orthopedic surgeries, where the penetration rate is thought to be 25-30%. Fibrin sealants can, however, be ineffective under wet surgical conditions. The penetration rate in other surgeries is estimated to be about 10-15%.

Fibrin-based sealants were originally made with bovine components. These components were judged to increase the risk of developing bovine spongiform encephalopathy (BSE), so second-generation commercial fibrin sealants (CSF) avoided bovine-derived materials. The antifibrinolytic tranexamic acid (TXA) was used instead of bovine aprotinin. Later, the TXA was removed, again due to safety issues. Today, Ethicon’s (JNJ) Evicel is an example of this product, which Ethicon says is the only all human, aprotinin free, fibrin sealant indicated for general hemostasis. Market growth in the Sealants sector is driven by the need for improved biocompatibility and stronger sealing ability—in other words, meeting the still-unsatisfied needs of physician end-users.

High Strength Medical Glues

Similar to that of sealants, the current market penetration of glues in the US is thought to be about 25% of eligible surgeries. There are several strong points in favor of the use of medical glues: their use can significantly reduce healthcare costs, for example by reducing time in the surgical suite, reducing the risk of a bleed, which may mean a return trip to the OR, and general ease of use. Patients seem to prefer the glues over receiving sutures for an external wound, as glues can provide a suture-free method of closing wounds. In addition, if glues are selected over sutures, the physician can avoid the need (and cost) of administering local anesthesia to the wound site.

Hemostats

Hemostats are normally used in surgical procedures only when conventional bleeding control methods are ineffective or impractical. The hemostat market offers opportunities as customers seek products that better meet their needs. Above and beyond having hemostats that are effective and reliable, additional improvements that they wish to see in hemostat products include: laparoscopy-friendly; work regardless of whether the patient is on anticoagulants or not; easy to prepare and store, with a long shelf life; antimicrobial; transparent so that the surgeon continues to have a clear field of view; and non-toxic; i.e. preferably not made from human or animal materials.

Bioengineered skin and skin substitutes in wound management

Bioengineered skin was developed because of the need to cover extensive burn injuries in patients who no longer had enough skin for grafting. Not so long ago, a patient with third degree burns over 50% of his body surface usually died from his injuries. That is no longer the case. Today, even someone with 90% total body surface area burn has a good chance of surviving. With the array of bioengineered skin and skin substitutes available today, such products are also finding use for chronic wounds, in order to prevent infection, speed healing and provide improved cosmetic results.

Estimated Worldwide Wound Prevalence by Etiology, 2015

Source: MedMarket Diligence, LLC; Report #S251.

Skin used in wound care may be autograft (from the patient’s own body, as is often the case with burn patients), allograft (cadaver skin), xenogeneic (from animals such as pigs or cows), or a combination of these. Bioengineered skin substitutes are synthetic, although they, too, may be combined with other products. It consists of an outer epidermal layer and (depending on the product) a dermal layer, which are embedded into an acellular support matrix. This product may be autogenic, or from other sources. Currently most commercial bioengineered skin is sheets of cells derived from neonatal allogenic foreskin. This source is chosen for several reasons: because the cells come from healthy newborns undergoing circumcision, and therefore the tissue would have been discarded anyway; foreskin tissue is high in epidermal keratinocyte stem cells, which grow vigorously; and because allergic reactions to this tissue is uncommon.

Bioengineered skin and skin substitutes are on the market and in development by LifeCell (Acelity), Organogenesis, Smith & Nephew, Organogenesis, Vericel Corporation (formerly Aastrom Biosciences), Mölnlycke Health Care, Integra LifeSciences, Smith & Nephew, Stratatech Corporation, A-Skin, University Children’s Hospital, Zurich; EuroSkinGraft.

The market may become more crowded as growth in the adoption of these products draws more competitors. Bioengineered skin and skin substitutes will drive more revenue than any other segment of the broader wound management market.

Factors Affecting Wound Healing

Excerpted from, “Worldwide Wound Management, Forecast to 2024: Established and Emerging Products, Technologies and Markets in the Americas, Europe, Asia/Pacific and Rest of World”, Report #S251.

A delicate physiological balance must be maintained during the healing process to ensure timely repair or regeneration of damaged tissue. Wounds may fail to heal or have a greatly increased healing time when unfavorable conditions are allowed to persist. An optimal environment must be provided to support the essential biochemical and cellular activities required for efficient wound healing and to remove or protect the wound from factors that impede the healing process.

Factors affecting wound healing may be considered in one of two categories depending on their source. Extrinsic factors impinge on the patient from the external environment, whereas intrinsic factors directly affect the performance of bodily functions through the patient’s own physiology or condition.

Preparation of the wound bed (WBP) is essential for the support of efficient and effective healing, especially when advanced wound care products are to be used. WBP involves removing localized barriers to healing, such as exudate, dead tissue or infected tissue.

Wound Bed Preparation: the TIME and DIMES acronyms

WBP involves debridement, reduction and neutralization of the bioburden and management of exudate from the wound. The TIME acronym provides a systematic way to manage wounds by looking at each stage of wound healing. The goal is to have the best, thoroughly-vascularized wound bed possible.

TIME stands for:

  • T: Tissue, non-viable or deficient.

The wound care professional should look for non-viable tissue, which includes necrotic tissue, tissue which has sloughed off, or non-viable tendon or bone.

  • I: Infection or Inflammation

Examine the wound for infection, inflammation or other signs of infection. Are there clinical signs that there may be a problem with bacterial bioburden?

  • M: Moisture Balance

Is the wound too dry, or does it have excess exudate?

What is the objective of topical therapy: absorption or drainage?

  • E: Edge of wound—non-advancing or undermined

Examine the edges of the wound. Are the edges undermined, or is the epidermis failing to migrate across the granulation tissue?

The DIMES acronym is very similar to TIME:

  • Debridement (autolytic)

For wounds with the ability to heal, adequate and repeated debridement is an important first step in removing necrotic tissue. Debridement may also help healing by removing both senescent cells that are no longer capable of normal cellular activities and biofilms that may be shielding bacterial colonies.

  • Infection/Inflammation

The level of bacterial damage may include contamination (organisms present), colonization (organisms present which may cause surface damage if critically colonized) or infection. Treatment needs to make a match between the individual patient’s wound and the appropriate product.

  • Moisture balance

Clinicians need to create a careful balance in the wound such that the environment is neither too wet nor too dry. The environment itself will change as the wound heals.

  • Edge/Environment

The clinician should carefully examine and monitor the wound edge. If the wound edge is not migrating after appropriate wound bed preparation, and if healing appears to be stalled, then more advanced wound care therapies should be considered.

  • Supportive Products and Services

There are additional products which support wound healing yet don’t fall into one of these steps. For example, proper nutritional support is important to achieving the goal of a fully healed wound.

Extrinsic Factors

Extrinsic factors affecting wound healing include:

  • Mechanical stress
  • Debris
  • Temperature
  • Desiccation and maceration
  • Infection
  • Chemical stress
  • Medications
  • Other factors such as alcohol abuse, smoking, and radiation therapy

Mechanical Stress

Mechanical stress factors include pressure, shear, and friction. Pressure can result from immobility, such as experienced by a bed- or chair-bound patient, or local pressures generated by a cast or poorly fitting shoe on a diabetic foot. When pressure is applied to an area for sufficient time and duration, blood flow to the area is compromised and healing cannot take place. Shear forces may occlude blood vessels, and disrupt or damage granulation tissue. Friction wears away newly formed epithelium or granulation tissue and may return the wound to the inflammatory phase.

Debris

Debris, such as necrotic tissue or foreign material, must be removed from the wound site in order to allow the wound to progress from the inflammatory stage to the proliferative stage of healing. Necrotic debris includes eschar and slough. The removal of necrotic tissue is called debridement and may be accomplished by mechanical, chemical, autolytic, or surgical means. Foreign material may include sutures, dressing residues, fibers shed by dressings, and foreign material which were introduced during the wounding process, such as dirt or glass.

Temperature

Temperature controls the rate of chemical and enzymatic processes occurring within the wound and the metabolism of cells and tissue engaged in the repair process. Frequent dressing changes or wound cleansing with room temperature solutions may reduce wound temperature, often requiring several hours for recovery to physiological levels. Thus, wound dressings that promote a “cooling” effect, while they may help to decrease pain, may not support wound repair.

Desiccation and Maceration

Desiccation of the wound surface removes the physiological fluids that support wound healing activity. Dry wounds are more painful, itchy, and produce scab material in an attempt to reduce fluid loss. Cell proliferation, leukocyte activity, wound contraction, and revascularization are all reduced in a dry environment. Epithelialization is drastically slowed in the presence of scab tissue that forces epithelial cells to burrow rather than freely migrate over granulation tissue. Advanced wound dressings provide protection against desiccation.

Maceration resulting from prolonged exposure to moisture may occur from incontinence, sweat accumulation, or excess exudates. Maceration can lead to enlargement of the wound, increased susceptibility to mechanical forces, and infection. Advanced wound products are designed to remove sources of moisture, manage wound exudates, and protect skin at the edges of the wound from exposure to exudates, incontinence, or perspiration.

Infection

Infection at the wound site will ensure that the healing process remains in the inflammatory phase. Pathogenic microbes in the wound compete with macrophages and fibroblasts for limited resources and may cause further necrosis in the wound bed. Serious wound infection can lead to sepsis and death. While all ulcers are considered contaminated, the diagnosis of infection is made when the wound culture demonstrates bacterial counts in excess of 105 microorganisms per gram of tissue. The clinical signs of wound infection are erythema, heat, local swelling, and pain.

Chemical Stress

Chemical stress is often applied to the wound through the use of antiseptics and cleansing agents. Routine, prolonged use of iodine, peroxide, chlorhexidine, alcohol, and acetic acid has been shown to damage cells and tissue involved in wound repair. Their use is now primarily limited to those wounds and circumstances when infection risk is high. The use of such products is rapidly discontinued in favor of using less cytotoxic agents, such as saline and nonionic surfactants.

Medication

Medication may have significant effects on the phases of wound healing. Anti-inflammatory drugs such as steroids and non-steroidal anti-inflammatory drugs may reduce the inflammatory response necessary to prepare the wound bed for granulation. Chemotherapeutic agents affect the function of normal cells as well as their target tumor tissue; their effects include reduction in the inflammatory response, suppression of protein synthesis, and inhibition of cell reproduction. Immunosuppressive drugs reduce WBC counts, reducing inflammatory activities and increasing the risk of wound infection.

Other Extrinsic Factors

Other extrinsic factors that may affect wound healing include alcohol abuse, smoking, and radiation therapy. Alcohol abuse and smoking interfere with body’s defense system, and side effects from radiation treatments include specific disruptions to the immune system, including suppression of leukocyte production that increases the risk of infection in ulcers. Radiation for treatment of cancer causes secondary complications to the skin and underlying tissue. Early signs of radiation side effects include acute inflammation, exudation, and scabbing. Later signs, which may appear four to six months after radiation, include woody, fibrous, and edematous skin. Advanced radiated skin appearances can include avascular tissue and ulcerations in the circumscribed area of the original radiation. The radiated wound may not become evident until as long as 10-20 years after the end of therapy.

Intrinsic Factors

Intrinsic factors that directly affect the performance of healing are:

  • Health status
  • Age factors
  • Body build
  • Nutritional status

Health Status

Chronic diseases, such as circulatory conditions, anemias and autoimmune diseases, influence the healing process as a result of their influence on a number of bodily functions. Illnesses that cause the most significant problems include diabetes, chronic obstructive pulmonary disease (COPD), arteriosclerosis, peripheral vascular disease (PVD), heart disease, and any conditions leading to hypotension, hypovolemia, edema, and anemia. While chronic diseases are more frequent in the elderly, wound healing will be delayed in any patient with a pre-existing underlying illness.

Chronic circulatory diseases which reduce blood flow, such as arterial or venous insufficiency, lower the amount of oxygen available for normal tissue activity and replacement. Anemias such as sickle-cell anemia result in reduced delivery of oxygen to tissues and decreased ability to support wound healing.

Normal immune function is required during the inflammatory phase by providing the WBCs (white blood cells) that orchestrate or coordinate the normal sequence of events in wound healing. Autoimmune diseases such as lupus and rheumatoid arthritis interfere with normal collagen deposition, and impair granulation.

Diabetes is associated with delayed cellular response to injury, compromised cellular function at the site of injury, defects in collagen synthesis, and reduced wound tensile strength after healing. Diabetes-related peripheral neuropathy (DPN), which reduces the ability to feel pressure or pain, contributes to a tendency to ignore pressure points and avoid pressure relief strategies.

Acquired Immune Deficiency Syndrome

Patients with acquired immunodeficiency syndrome (AIDS) have significant impact on the wound healing market as their numbers rise and their average life expectancy increases. Patients in the latter stages of the disease experience drastic reductions in mobility, activity, and nutritional status, placing them at high risk for the development of pressure ulcers. Minor scrapes or abrasions are at high risk for infection and may progress to full-thickness wounds requiring antibiotic therapy and aggressive wound management. Skin tumors, such as Kaposi’s sarcoma, lead to surgical incisions closed by secondary intention requiring the use of appropriate dressings.

The skin of AIDS patients becomes drier as the syndrome progresses. As the CD4+ T cell count falls below 400/mm3, pruritus increases and erythematous patches appear on the skin, progressing to ichthyosis and appearing as large polygonal scales, especially on the lower limbs. Histological changes include hyperkeratosis and thinning of the granular layer of the epidermis. As skin becomes more fragile, care must be exercised in the selection of tapes and adhesive dressings to avoid skin stripping and skin tears.

Age Factors

Observable changes in wound healing in the elderly include increased time to heal and the fragile structure of healed wounds. Delays are speculated to be the result of a general slowing of metabolism and structural changes in the skin of elderly people. Structural changes include a flattening of the dermal-epidermal junction that often leads to skin tears, reduced quality and quantity of collagen, reduced padding over bony prominences, and reduction in the intensity of the immune response.

Body Build

Body build can affect the delivery and availability of oxygen and nutrients at the wound site. Underweight individuals may lack the necessary energy and protein reserves to provide sufficient raw materials for proliferative wound healing. Bony prominences lack padding and become readily susceptible to pressure due to the reduced blood supply of wounds associated with bony prominences. Poor nutritional habits and reduced mobility of overweight individuals lead to increased risk of wound dehiscence, hernia formation, and infection.

Nutritional Status

Healing wounds, especially full-thickness wounds, require an adequate supply of nutrients. Wounds require calories, fats, proteins, vitamins and minerals, and adequate fluid intake. Calories provide energy for all cellular activity, and when in short supply in the diet, the body will utilize stored fat and protein. The metabolism of these stored substances causes a reduction in weight and changes in pressure distribution through reduction of adipose and muscle padding. Sufficient dietary calories maintain padding and ensure that dietary protein and fats are available for use in wound healing. In addition, adequate levels of protein are necessary for repair and replacement of tissue. Increased protein intake is particularly important for wounds where there is significant tissue loss requiring the production of large amounts of connective tissue. Protein deficiencies have been associated with poor revascularization, decreased fibroblast proliferation, reduced collagen formation, and immune system deficiencies.

Reduced availability of vitamins, minerals, and trace elements will also affect wound healing. Vitamin C is required for collagen synthesis, fibroblast functions, and the immune response. Vitamin A aids macrophage mobility and epithelialization. Vitamin B complex is necessary for the formation of antibodies and WBCs, and Vitamin B or thiamine maintains metabolic pathways that generate energy required for cell reproduction and migration during granulation and epithelialization. Iron is required for the synthesis of hemoglobin, which carries oxygen to the tissues, and copper and zinc play a role in collagen synthesis and epithelialization.

Adequate nutrition is an often-overlooked requirement for normal wound healing. Inadequate protein-calorie nutrition, even after just a few days of starvation, can impair normal wound-healing mechanisms. For healthy adults, daily nutritional requirements are approximately 1.25-1.5 g of protein per kilogram of body weight and 30-35 calories/kg.  These requirements should be increased for those with sizable wounds.

Malnutrition should be suspected in patients presenting with chronic illnesses, inadequate societal support, multisystem trauma, or GI or neurologic problems that may impair oral intake. Protein deficiency occurs in about 25% of all hospitalized patients.

Chronic malnutrition can be diagnosed by using anthropometric data to compare actual and ideal body weights and by observing low serum albumin levels. Serum prealbumin is sensitive for relatively acute malnutrition because its half-life is 2-3 days (vs 21 d for albumin). A serum prealbumin level of less than 7 g/dL suggests severe protein-calorie malnutrition.

Vitamin and mineral deficiencies also require correction. Vitamin A deficiency reduces fibronectin on the wound surface, reducing cell chemotaxis, adhesion, and tissue repair. Vitamin C is required for the hydroxylation of proline and subsequent collagen synthesis.

Vitamin E, a fat-soluble antioxidant, accumulates in cell membranes, where it protects polyunsaturated fatty acids from oxidation by free radicals, stabilizes lysosomes, and inhibits collagen synthesis. Vitamin E inhibits prostaglandin synthesis by interfering with phospholipase-A2 activity and is therefore anti-inflammatory. Vitamin E supplementation may decrease scar formation.

Zinc is a component of approximately 200 enzymes in the human body, including DNA polymerase, which is required for cell proliferation, and superoxide dismutase, which scavenges superoxide radicals produced by leukocytes during debridement.

The global dynamics of cardiovascular surgical and interventional procedures

This is an excerpt from Report #C500, “Cardiovascular Procedures to 2022.”

Cardiovascular Procedures in 2016

• Coronary artery bypass graft (CABG) surgery;
 • Coronary angioplasty and stenting;
 • Lower extremity arterial bypass surgery;
  • Percutaneous transluminal angioplasty (PTA) with and without bare metal and drug-eluting stenting;
  • Peripheral drug-coated balloon angioplasty;
  • Peripheral atherectomy;
  • Surgical and endovascular aortic aneurysm repair;
  • Vena cava filter placement
  • Endovenous ablation;
  • Mechanical venous thrombectomy;
  • Venous angioplasty and stenting;
  • Carotid endarterectomy;
  • Carotid artery stenting;
  • Cerebral thrombectomy;
  • Cerebral aneurysm and AVM surgical clipping;
  • Cerebral aneurysm and AVM coiling & flow diversion;
  • Left Atrial Appendage closure;
  • Heart valve repair and replacement surgery;
  • Transcatheter valve repair and replacement;
  • Congenital heart defect repair;
  • Percutaneous and surgical placement of temporary and permanent mechanical cardiac support devices;
  • Pacemaker implantation;
  • Implantable cardioverter defibrillator placement;
  • Cardiac resynchronization therapy device placement;
  • Standard SVT & VT ablation; and
  • Transcatheter AFib ablation

In 2016, the cumulative worldwide volume of the most prevalent cardiovascular procedures (at right) is projected to approach 15.05 million surgical and transcatheter interventions. This will include:

  • roughly 4.73 million coronary revascularization procedures via CABG and PCI (or about 31.4% of the total),
  • close to 4 million percutaneous and surgical peripheral artery revascularization procedures (or 26.5% of the total);
  • about 2.12 million cardiac rhythm management procedures via implantable pulse generator placement and arrhythmia ablation (or 14.1% of the total);
  • over 1.65 million CVI, DVT, and PE targeting venous interventions (representing 11.0% of the total);
  • more than 992 thousand surgical and transcatheter heart defect repairs and valvular interventions (or 6.6% of the total);
  • close to 931 thousand acute stroke prophylaxis and treatment procedures (contributing 6.2% of the total);
  • over 374 thousand abdominal and thoracic aortic aneurysm endovascular and surgical repairs (or 2.5% of the total); and
  • almost 254 thousand placements of temporary and permanent mechanical cardiac support devices in bridge to recovery, bridge to transplant, and destination therapy indications (accounting for about 1.7% of total procedure volume).

During the period 2016 to 2022, the total worldwide volume of covered cardiovascular procedures is forecast to expand on average by 3.7% per annum to over 18.73 million corresponding surgeries and transcatheter interventions in the year 2022. The largest absolute gains can be expected in peripheral arterial interventions (thanks to explosive expansion in utilization of drug-coated balloons in all market geographies), followed by coronary revascularization (supported by continued strong growth in Chinese and Indian PCI utilization) and endovascular venous interventions (driven by grossly underserved patient caseloads within the same Chinese and Indian market geography).

The latter (venous) indications are also expected to register the fastest (5.1%) relative procedural growth, followed by peripheral revascularization (with 4.0% average annual advances) and aortic aneurysm repair (projected to show a 3.6% average annual expansion).

http://mediligence.com/c500/

Geographically, Asian-Pacific (APAC) market geography accounts for slightly larger share of the global CVD procedure volume than the U.S. (29.5% vs 29,3% of the total), followed by the largest Western European states (with 23.9%) and ROW geographies (with 17.3%). Because of the faster growth in all covered categories of CVD procedures, the share of APAC can be expected to increase to 33.5% of the total by the year 2022, mostly at the expense of the U.S. and Western Europe.

However, in relative per capita terms, covered APAC territories (e.g., China and India) are continuing to lag far behind developed Western states in utilization rates of therapeutic CVD interventions with roughly 1.57 procedures per million of population performed in 2015 for APAC region versus about 13.4 and 12.3 CVD interventions done per million of population in the U.S. and largest Western European countries.

The rise and fall of medical technologies

When does one recognize that horse-and-buggy whips are in decline and auto-mobiles are on the rise?

When does one recognize that a new technology is a definite advance over established ones in the treatment of particular disease, in cost or quality?

Technologies go through life cycles.

A medical technology is introduced that is found effective in the management of a disease. Over time, the technology is improved upon marginally, but eventually a new technology, often radically different, emerges that is more effective or better (cheaper, less invasive, easier to use). It enters the market, takes market share from and grows, only to be later eclipsed by a new (apologies) “paradigm”. Each new technology, marginal or otherwise, advances the limit of what is possible in care.

Predicting the marginal and the more radical innovation is necessary to illustrate where medicine is headed, and its impact. Many stakeholders have interest in this — insurance companies (reimbursing technologies or covering the liabilities), venture capitalists, healthcare providers, patients, and the medical technology companies themselves.

S-curves illustrate the rise in performance or demand over time for new technologies and show the timing and relative impact of newer technologies when they emerge. Importantly, the relative timing and impact of emerging technologies can be qualitatively and quantitatively predicted. Historic data is extremely useful predicting the rise and fall of specific medical technologies in specific disease treatment.

Following are two examples of diseases with multiple technologies arcing through patient demand over time.

The treatment of ischemic heart disease, given the seriousness of the disease and its prevalence, has a long history in medicine and within the past fifty years has a remarkable timeline of innovations. Ischemia is condition in which inadequate blood flow to an area due to constriction of blood vessels from inflammation or atherosclerosis can cause cell death. In the case of cardiac ischemia, in which the coronary arteries that supply the heart itself with blood are occluded, the overall cell death can result in myocardial infarction and death.

The effort to re-establish adequate blood flow to heart muscle has evolved from highly invasive surgery in which coronary artery bypass graft (CABG) requires cutting through the patient’s sternum and other tissues to access the heart, then graft arteries and/or veins to flow to the poorly supplied tissue, to (2) minimally invasive, endoscope procedures that do not require cutting the sternum to access the heart and perform the graft and significantly improve healing times and reduced complications, to as illustrated, multiple technologies rise and fall over time with their impacts and their timing considered.

Technology S-Curves in the Management of Ischemic Heart Disease

(Note: These curves are generally for illustrative purposes only; some likely dynamics may not be well represented in the above. Also note that, in practice, demand for old technologies doesn’t cease, but declines at a rate connected to the rise of competing technologies, so after peaking, the S-curves start a descent at various rates toward zero. Also, separately note that the “PTCA” labeled curve corresponds to percutaneous transluminal coronary angioplasty, encompassing the percutaneous category of approaches to ischemic heart disease. PTCA itself has evolved from balloon angioplasty alone to the adjunctive use of stents of multiple material types with or without drug elution and even bioabsorbable stents.)

Resulting Technology Shifts

Falling: Open surgical instrumentation, bare metal stents.
Rising and leveling: thoracoscopic instrumentation, monitors
Rising later: stem-cells, extracellular matrices, atherosclerosis-reducing drugs
Rising even later: gene therapy

The minimally invasive technologies enabled by thoracoscopy (used in MIDCAB) and catheterization pulled just about all the demand out of open coronary artery bypass grafting, though the bare metal stents used initially alongside angioplasty have also been largely replaced by drug-eluting stents, which also may be replaced by drug-eluting balloon angioplasty. Stem cells and related technologies used to deliver them will later represent new growth in treatment of ischemia, at least to some degree at the expense of catheterization (PTCA and percutaneous CABG). Eventually, gene therapy may prove able to prevent the ischemia to develop in the first place.

  • Wound Management Past, Current, and Future Technologies
    • Gauze bandages/dressings
    • Hydrogel, alginate, and antimicrobial dressings
    • Negative pressure wound therapy (NPWT)
    • Bioengineered skin substitutes
    • Growth factors

Another great example of a disease or condition treated by multiple evolving technologies over time is wound management, which has evolved from simple gauze dressings to advanced dressings, to systems like negative pressure wound therapy, hyperbaric oxygen and others, to biological growth factors to bioengineered skin and skin substitutes.

Resulting Technology Shifts

Falling: Traditional gauze and other simple dressings
Falling: NPWT, hyperbaric oxygen
Rising: Advanced wound dressings, bioengineered skin, growth factors

Wound management has multiple technologies concurrently available, rather than sequential (when one largely replaces the other) over time. Unsurprisingly, traditional dressings are in decline. Equipment-related technologies like NPWT and hyperbaric oxygen are on the wane as well. While wound management is not a high growth area, advanced dressings are rising due to their ability to heal wounds faster, an important factor considering that chronic, slow-healing wounds are a significant contributor to high costs. Bioengineered skin is patient-specific, characterized by faster healing and, therefore, rising.
