Fixing congenital heart defects on a global scale

Congenital heart abnormalities – which occur in an estimated 1.1% to 1.3% of infants born in the U.S. and worldwide each year – constitute leading cause of birth defect-related deaths. To-date, clinicians have identified and documented almost four dozens distinctive heart defects in newly born ranging from relatively simple and easily correctible abnormalities to complex and multiple anatomical malformations.

The most commonly encountered congenital heart abnormalities accounting for the majority of all diagnosed cases include: ventricular septal defect (VSD); tetralogy of Fallot (TOF); transposition of great vessels (TGV); atrioventricular septal defect (ASD); and coarctation of aorta (COA).

Selection of treatment protocols for congenital heart defects depends on the morphology of the abnormality and its immediate and long-term impact on cardiopulmonary function and patient’s prognosis (threat to survival).

Many asymptomatic patients with minor defects (typically representing unresolved inheritance from normal fetal development, such as trans-septal conduits that are supposed to close at birth) might be put on a “watchful waiting” regime.

Some symptomatic and functionally compromising congenital heart defects can be treated with minimally invasive percutaneous (transcatheter) techniques. To-date, percutaneous repair tools have been developed and clinically tested for several common congenital myocardial abnormalities including: patent ductus arteriosus (PDA), atrial septal defect, ventricular septal defect and patent foramen ovale (PFO). In all instances, the primary objective of the transcatheter approach was to reduce morbidity, mortality and costs associated with the procedure by achieving septal repair or closure via endovascular implantation of specially-configures occluding or sealing devices.

In cases involving complex, debilitating and life threatening congenital myocardial abnormalities (such as Tetralogy of Fallot, transposition of great vessels, etc.) one or several corrective open heart surgeries represent the only route to patient survival. Such surgeries are typically performed during the first year of infant’s life and carry a 5% risk of mortality, on average.

Based on the available industry data and MedMarket Diligence estimates, in 2015, approximately 387 thousand congenital heart defect repair procedures were performed worldwide, of which less invasive transcatheter interventions accounted for about 24.3% and open heart corrective surgeries for the remaining 75.7%.

During the forecast period covered in the report, the cumulative global volume of congenital heart defect repair procedures is projected to grow 1.9% per annum to approximately 444 thousand percutaneous and surgical interventions in the year 2022. The usage of transcatheter procedures can be expected to experience significantly faster 9.0% average annual growth (partially at the expense of corrective open heart surgeries for septal defects), reflecting mostly accelerated transition to minimally invasive percutaneous septal defect repair in APAC and ROW market geographies (where the latter techniques currently used only in 15% to 22% of corresponding procedures, compared to 60% to 75% in Western Europe and the U.S.).

Upside from innovation, emerging markets for sealants, glues, hemostats

A great deal of market development has yet to take place in the field of wound closure, especially for advanced sealants, glues, and hemostats — let’s just for convenience call them “liquid closure” (as opposed to sutures/staples/clips). It is currently in an evolving, growing, consolidating, tweaking state of change, with currently more upside coming out of Asia than from innovations in sealing, adhesion, or hemostasis.

Market players dominant in one geography are absent in others. The rate of market growth arising from innovation lags growth from penetrating emerging markets, where manufacturers have rushed to pick the easy fruit.

Challenges remain in order for “liquid closure” to more deeply penetrate a caseload otherwise served by docs using strong, easy-to-use sutures, clips, and staples. Sealants are terrific in adjunctive use by “caulking” suture lines to ensure nothing leaks between, no matter how strongly the clips, etc. are holding. But the strength of sealing and adhesion are not sufficient for most products to do the job alone. A “liquid closure” must be many things with high standards that have largely yet to be met.

Hemostats, though, given their simple function to keep the life from draining out of people, have succeeded handsomely in saving lives.

For the near term, the growth in liquid closure sales is evident most strongly in Asia, with income and other drivers there giving life to an otherwise staid market, for the time being…

The Five Highest Growth Cardiovascular Procedures

#5. Cerebral thrombectomy.

The initial use of cerebral thrombectomy systems has been a disappointment. It is generally assumed that the situation with end-user adoption is likely to improve dramatically in two-three years from now, when results of the ongoing major U.S. and international trials with novel cerebral thrombectomy devices become available. Growth will exceed 11% annually through 2022.

#4 Below-the-knee drug-coated balloon angioplasty for superficial femoral artery. 

There is now a broad-based consensus among leading interventional radiologists that peripheral angioplasty using DCBs should be seen as a first-line revascularization option for both primary treatment and revision of advanced arterial occlusions in the SFA vascular territory. This will lead to better than 14% annual growth in these procedures through 2022.

#3 Transcatheter heart valve replacement. 

The use of transcatheter techniques in heart valve replacement and repair is projected to grow at over 14%, to be supported by the anticipated regulatory approval of TAVR procedures for intermediate risk patients in late 2016, and, plausibly, for standard surgical risk caseloads by 2019.

#2 Left atrial appendage endovascular closure in AFib.

The global volume of endovascular LAA closure procedures is projected to experience a robust double-digit growth expanding an average of over 14% annually, nearly doubling to an estimated 52 thousand corresponding interventions in the year 2022. Anticipated strong growth in the endovascular LAA closure utilization will be driven by increasing penetration of the Asian-Pacific (primarily Chinese and Indian) market geography with an extra boost from the recent U.S. launch of transcatheter LAA closure systems. Advances in the mature European market and emerging ROW marketplace are likely to stay below projected average growth rates.

#1 Lower extremity angioplasty and DES procedures.

Lower extremity angioplasty and drug-eluting stenting is forecast to increase almost three-fold from 2016 to 2022.

From 2015 to 2022, the cumulative global volume of PTA procedures is projected to expand an average of 4.2% per annum to year 2022. The cited expansion will be driven largely by a strong annual procedural growth in the APAC region (primarily in China and India undergoing aggressive transition to modern interventional radiology practices), which is forecast to account for about over a third of PTAs performed worldwide in 2022. The U.S. and Western European geographies can be expected to register only a moderate PTA procedural growth to be supported mostly by increasing penetration of the SFA patient caseloads with DES-based interventions, but the worldwide utilization of stented PTAs (especially these employing DES devices) is forecast to grow at significantly faster (4.2% and 19.1%) average annual rates to over 986,000 and 203,000 corresponding procedures in the year 2022.

In very general terms, the category “cardiovascular diseases” (CVD) refers to a variety of acute and chronic medical conditions resulting in the inability of cardiovascular system to sustain an adequate blood flow and supply of oxygen and nutrients to organs and tissues of the body. The CVD conditions could be manifested by the obstruction or deformation of arterial and venous pathways, distortion in the electrical conducting and pacing activity of the heart, and impaired pumping function of the heart muscle, or some combination of circulatory, cardiac rhythm, and myocardial disorders

The scope of this report covers surgical and interventional therapeutic procedures commonly used in the management of acute and chronic conditions affecting myocardium and vascular system. The latter include ischemic heart disease (and its life threatening manifestations like AMI, cardiogenic shock, etc.); heart failure; structural heart disorders (valvular abnormalities and congenital heart defects); peripheral artery disease (and limb and life threatening critical limb ischemia); aortic disorders (AAA, TAA and aortic dissections); acute and chronic venous conditions (such as deep venous thrombosis, pulmonary embolism and chronic venous insufficiency); neurovascular pathologies associated with high risk of hemorrhagic and ischemic stroke (such as cerebral aneurysms and AVMs, and high-grade carotid/intracranial stenosis); and cardiac rhythm disorders (requiring correction with implantable pulse generators/IPG or arrhythmia ablation).

The report offers current assessment and projected procedural dynamics (2015 to 2022) for primary market geographies (e.g., United States, Largest Western European Countries, and Major Asian States) as well as the rest-of-the-world.

The cited procedural assessments and forecasts are based on the systematic analysis of multiplicity of sources including (but not limited to):

  • latest and historic company SEC filings, corporate presentations, and interviews with product management and marketing staffers;
  • data released by authoritative international institutions (such as OECD and WHO), and national healthcare authorities;
  • statistical updates and clinical practice guidelines from professional medical associations (like AHA, ACC, European Society of Cardiology, etc.);
  • specialty presentations at major professional conferences (e.g., TCT, AHA Scientific Sessions, EuroPCR, etc.);
  • publications in major medical journals (JAMA, NEJM, British Medical Journal, etc.) and specialty magazines (CathLab Digest, EP Digest, Endovascular Today, etc.);
  • findings from relevant clinical trials;
  • feedbacks from leading clinicians (end-users) in the field on device/procedure utilization trends and preferences; and
  • policy papers by major medical insurance carriers on uses of particular surgical and interventional tools and techniques, their medical necessity and reimbursement.

Surgical and Interventional Procedures Covered in the report include:

  • 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, cumulative worldwide volume of the aforementioned CVD procedures 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 forecast period, 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).

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.

Hemostats Development, Sales Growth By Region

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.

Hemostat sales are being driven by several factors. These include the growth in the volume of inpatient and of ambulatory same-day surgeries, as well as the growth in minimally-invasive surgical procedure volumes. Effective hemostats may also reduce the time spent in the operating suite, which directly saves both surgeons and hospitals time and money. If the products can also reduce the risk of adhesions, then the patient may be able to avoid a second surgery sometime down the road.

Most markets for hemostats (as well as for sealants and glues) are experiencing very strong competition, and the US market, although the largest, is also saturated for many medical devices and products. Price controls are high priority in the European Union in order to control healthcare budgets. Japan, despite recent legislation making entry slightly easier, remains a tough market to crack. The easier-entry markets tend to be outside of the EU and Japan.

However, emerging markets are often characterized by fragile or unsteady economies, and healthcare markets that may not be ready to receive the more advanced sealant, glue and hemostat products. These hurdles must be overcome using shrewd market strategies and local offices in order to gain a foothold. Not all companies have the funds required to get into these markets directly, in which case a joint venture may be the best route.

The Demand for Sealants, Glues, and Hemostats in 2016

The following is drawn from “Worldwide Markets for Medical and Surgical Sealants, Glues, and Hemostats, 2015-2022.” Report #S290.

The need for surgical sealants, glues and hemostats is directly related to the clinical caseload and procedure volumes, as well as to the adoption of these products for multiple uses, such as the use of one product for sealing, hemostasis and anti-adhesion. It is fair to say that use of these products has become routine in the surgical suite and in other clinical locations. Procedure volumes are in turn driven by demographic forces, including global aging populations, while regulatory changes will continue to influence uptake of these products.

Medical Sealants

Fibrin sealants are made of a combination of thrombin and fibrinogen. These sealants may be sprayed on the bleeding surface, or applied using a patch. Surgical sealants might be made of glutaraldehyde and bovine serum albumin, polyethylene glycol polymers, and cyanoacrylates.

Sealants are most often used to stop bleeding over a large area. If the surgeon wishes to fasten down a flap without using sutures, or in addition to using sutures, then the product used is usually a medical glue.

Hemostatic Products

The surgeon and the perioperative nurse have a variety of hemostats from which to choose, as they are not all alike in their applications and efficacy. Selection of the most appropriate hemostat requires training and experience, and can affect the clinical outcome, as well as decrease treatment costs. Some of the factors that enter into the decision-making process include the size of the wound, the amount of hemorrhaging, potential adverse effects, whether the procedure is MIS or open surgery, and others.

Active hemostats contain thrombin products which may be derived from several sources, such as bovine pooled plasma purification, human pooled plasma purification, or through human recombinant manufacturing processes. Flowable-type hemostats are made of a granular bovine or porcine gelatin that is combined with saline or reconstituted thrombin, forming a flowable putty that may be applied to the bleeding area.

Medical Glues

Sealants and glues are terms which are often used interchangeably, which can be confusing. In this report, a medical glue is defined as a product used to bond two surfaces together securely. Surgeons are increasingly reaching for medical glues to either help secure a suture line, or to replace sutures entirely in the repair of soft tissues. Medical glues are also utilized in repairing bone fractures, especially for highly comminuted fractures that often involve many small fragments. This helps to spread out the force-bearing surface, rather than focusing weight-bearing on spots where a pin has been inserted.

Thus, the surgeon has a fairly wide array of products from which to choose. The choice of which surgical hemostat or sealant to use depends on several factors, including the procedure being conducted, the type of bleeding, severity of the hemorrhage, the surgeon’s experience with the products, the surgeon’s preference, the price of the product and availability at the time of surgery. For example, a product which has a long shelf life and does not require refrigeration or other special storage, and which requires no special preparation, usually holds advantages over a product which must be mixed before use, or held in a refrigerator during storage, then allowed to warm up to room temperature before use.

 

USA and Asia/Pacific Size Versus Growth in Sealants, Glues, Hemostats

The market dynamics in Asia/Pacific stand apart from those in the U.S. In the case of surgical sealants, glues, and hemostats, what stands out is the Size versus Growth metric.

Much of the potential in China, in particular, remains untapped (low volume, high growth), while in the U.S., these markets are more well established and, therefore, more penetrated.

Below are the size/growth “bubbles” for, alternating, the U.S. and Asia/Pacific.
