The Mechanical Hearth Valve

Investigation of the problem of thrombosis and investigation of the problem of refill of bifida-type prosthetic heart valve (St. Jude Medical Valve) Over the past 60 years, significant innovations in the design and manufacture of artificial heart valves that are beneficial to safety and hemodynamics It has been advanced. Since the late 1970s, mechanical heart valves have been widely used, successfully transplanting more than 100,000 Omni brand swash plate valves and 300,000 hall brand swash plate valves [1].

Tissue valves are used for mild elderly patients and do not require periodic testing. The lifetime of these valves is 15 - 20 years. Mechanical and tissue valve sizes range from 17 mm to 35 mm. Mechanical valves account for about 90% of all markets, but organized valves account for about 10% of all markets. In India, the medical implant market is estimated at 4.2 million dollars, most of which is imported. The medical implant market is one of the biggest healthcare markets and is a rapidly growing healthcare market. Future growth is driven by technical changes (active implants, spinal implants, tissue engineering), social and economic changes in developing countries, and changes in age structure in developed countries.

An important problem in patients with heart valves requiring a valve replacement surface is whether to select mechanical valves or tissue valves. Tissue valves taken from the bovine cardiac sac or pig heart valves are treated neutralized and not repelled from the body. The valve can be directly embedded or attached to the stent or frame. The main problem with the choice of tissue valves is that the typical lifespan of the valve is between 10 and 15 years and then needs to be replaced. For younger patients, valve life may be shorter. A serious risk of death associated with implant surgery makes valve life expectancy and patient life expectancy a key element of decision making
