Heart valves are thin tissue flaps located in the mammalian heart and they enable unidirectional blood flow between the 4 chambers during the cardiac cycle. The prime valves present within the human heart include the mitral valve, tricuspid valve, aortic valve, and pulmonary valve. The symptoms related to heart valve diseases vary as per the valve affected and the severity of the same. A heart valve disease is a mechanical problem and thus requires heart valve surgery for repairing or replacing a damaged valve. Valvular abnormalities are of primarily two types, namely stenosis and regurgitation. Stenosis is the narrowing of valves, causing blood accumulation, whereas regurgitation is failure of valve in closing properly, causing blood leakage into the heart.
Rising Geriatric Population Fuelling Market for Valve Repair and Replacement
The market is experiencing exponential growth owing to the rising geriatric population and lifestyle changes causing conditions that result in cardiovascular disorders. In addition, the rising medical tourism is also encouraging the demand for heart valve repair and replacement surgeries, thus fuelling the market. Furthermore, technological developments in heart valve repair and replacement surgeries and devices have also stimulated the market. On the other hand, the high number of complications and risks associated with these kind of surgeries, such as breathing problems, embolism, and irregular heartbeat, may have a negative effect on the growth of the market in the coming years. In addition, the absence of primary healthcare infrastructure in emerging countries may also impede the growth of the market for heart valve repair and replacement.
TAVR Emerges as Most Popular Method of Heart Valve Replacement
There are mainly three types of heart valves, namely mechanical heart valves, tissue heart valves and transcatheter heart valves, that can be used in the human body. The minimally invasive surgical method involves repairing of the valve without the removal of the old, damaged valve. Instead, this method puts the replacement valve into the place of aortic valve. This surgery is called transcatheter aortic valve replacement (TAVR). This surgical method emerged as the most swiftly growing segment in 2014 owing to its minimally invasive nature. This method is relatively new and is approved by the FDA and is used for people suffering from symptomatic aortic stenosis. In addition to TVR being a minimally invasive surgery, it also holds the advantage of being carried out via a tiny opening, thus leaving all the chest bones in place, unlike all other open heart surgeries.
North America Leads Global Market, Asia Pacific Market to Grow the Fastest
Geographically, the market is segmented into Europe, Asia Pacific, North America, and Rest of the World (ROW). Amongst these, in 2014, North America led the market for heart valve repair and replacement, with tissue heart replacement being the chief type of heart valve replacement method in the region. In terms of growth prospects, the Asia Pacific heart valve repair and replacement market will be the most swiftly growing market in forthcoming years.
