Prosthetic heart valve refers to acardiac surgery to replace an abnormal heart valve with an artificial heart valve. Replacement of diseased valves with prosthetic heart valves reducesthe morbidity and mortality associated with cardiac valve disorders.Technological advancements and increasing prevalence of heart valve diseases are some of the major factors that are driving the prosthetic heart valves market. Based on product, the prosthetic heart valves market can be segmented into mechanical heart valves, transcatheter heart valves, and tissue heart valves or bio-prosthetic valves.Tissue heart valves can be further segmented into stented tissue valve, stentless tissue valve, tissue-engineered valves, and homograft and heterograft valves. Mechanical heart valves include aortic valves and mechanical mitral valves. Tissue heart valves include tissue aortic valves and tissue mitral valves.
The tissue heart valves segment is the fastest-growing segment in the prosthetic heart valves market. Some types of heart valve disorders are valvular stenosis and valvular regurgitation. Conditions associated with heart valve disorders are congenital defects and acquired disorders. Some of the technologies for prosthetic heart valves aretranscatheter valves, anti-calcification technology, suture-less valves, polymers and carbon-based technologies . Mechanical heart valves are used inpercutaneous implantation and thoracotomy implantation. Tissue heart valves are used in homografts and heterografts.
