Valve stenosis is a structural heart disease. Stenosis is a term used for narrowing heart valves. Valve stenosis occurs when the heart valve narrows due to plaque buildup (atherosclerosis). In patients with valve stenosis, the blood cannot move properly in the rest of the body. In case of valve stenosis, the heart functions hard to compensate for the constricted opening and the blood flow is reduced to other chambers of the heart and/or to vital organs. Several conditions can cause valve stenosis, for example, calcium buildup, congenital heart defect, and rheumatic fever. A few common symptoms associated with valve stenosis are abnormal heart sound, fatigue, feeling faint or lightheaded, shortness of breath (especially during exercise), chest pain or tightness, heart murmur, and rapid or fluttering heartbeat. Major complications associated with valve stenosis are atrial fibrillation and heart failure. Several factors can increase the risk of developing valve stenosis including medical history of mitral valve stenosis, heart attack, and infections such as endocarditis or rheumatic fever.

Doctors can diagnose valve stenosis based on medical history and diagnostic tests. Common diagnostic tests conducted to diagnose the condition are echocardiogram, chest X-ray, exercise stress test, and cardiac catheterization.  

Rise in the prevalence of valve stenosis is anticipated to drive the global valve stenosis diagnosis & treatment market during the forecast period. Increase in government priority for treatment of valve stenosis is also expected to propel the global market in the near future. On the other hand, shortage of cardiology experts in Latin America and Middle East & Africa is likely to hamper the valve stenosis diagnosis & treatment market in these regions in the next few years. Favorable reimbursement policies in North America and Europe are anticipated to propel the market in these regions during the forecast period.

The global valve stenosis diagnosis & treatment market can be segmented based on type of stenosis, diagnostic test, treatment procedure, end-user, and region. In terms of type of stenosis, the market can be divided into mitral valve stenosis, aortic valve stenosis, pulmonary or pulmonic valve stenosis, and tricuspid valve stenosis. Based on treatment procedure, the market can be classified into surgical repair treatment and replacement treatment. In terms of diagnostic test, the market can be segregated into echocardiogram, chest X-ray, cardiac MRI, cardiac catheterization, and others. Based on end-user, the global valve stenosis diagnosis & treatment market can be categorized into hospitals, special clinics, and academic institutes & research organizations. The hospitals segment held a significant share of the market in 2017.

Based on region, the global valve stenosis diagnosis & treatment market can be segmented into North America, Latin America, Europe, Asia Pacific, and Middle East & Africa. North America accounted for a major share of the global market in 2017, followed by Europe and Asia Pacific. The U.S. held a significant share of the market in North America, in terms of revenue, in 2017. The market in Asia Pacific is expanding rapidly, due to increase in the number of patients suffering from valve stenosis in the region. Better health care infrastructure, economic growth, rise in the number of insurance payers, expanding private health care sector, and increase in awareness about diagnosis & treatment of valve stenosis among people in the region are expected to boost the market in Asia Pacific in the next few years. The valve stenosis diagnosis & treatment market in Latin America and Middle East & Africa is projected to expand at a moderate growth rate from 2018 to 2026.

Key players operating in the global valve stenosis diagnosis & treatment market are Abbott, Boston Scientific Corporation, Braile Biomédica, CryoLife, Inc., Edwards Lifesciences Corporation, LivaNova plc, Lepu Medical Technology, Medtronic, Micro Interventional Devices, Inc., and TTK HealthCare.
