Aortic Heart Valve Replacement

Aortic heart valve replacement is a surgical procedure where the aortic semilunar valve is replaced with a porcine, bovine, or mechanical counterpart. The procedure is performed 275,000 times a year. The mechanical valves have a higher risk of rejection by the body, which makes it a riskier procedure, whereas biological valves need to be made from animals or donated by an organ donor. The biological valves are controversial because many of them are made from pigs and cows, which are sacred in some religions or belief sets. The AVR surgery was first seen in the 1970s, but is beginning to evolve to more advanced methods. Transcatheter (non-invasive) approaches and regenerative studied have begun testing recently and are believed to be the future of the AVR procedure. My blog site will provide information regarding the causes, methods, effects, and controversy surrounding the AVR procedure, along with how it can improve in the future.
