Prosthetic heart valve

An artificial or prosthetic heart valve is a one-way heart valve implanted in the heart to replace a valve that is not functioning properly. Artificial heart valves can be classified into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.Mechanical valves are generally made of titanium and carbon. Tissue valves are made up of human or animal tissue and are called allografts or homografts. Credits: https://www.instagram.com/p/CMCJnv4Bg1H/?igshid=1wl6cxkpbty3r
