Detailed explanation-1: -Biologic prosthetic valves are associated with a higher risk of reoperation than mechanical valves because of structural valve deterioration, but mechanical valves typically necessitate lifelong anticoagulation, which increases the risk of hemorrhage and thromboembolism.

Detailed explanation-2: -The biggest drawback of mechanical heart valve replacement is the need for lifelong blood thinning medication (anticoagulation). Blood-thinning treatment comes with risk of bleeding complications. The most appealing part of a bioprosthetic heart valve is that it does typically require blood-thinning medication.

Detailed explanation-3: -The main drawback of a mechanical valve is the tendency for blood clots to form on its metal surfaces, which can lead to serious complications including heart attack or stroke.

Detailed explanation-4: -The biological valves made from animal tissue are called xenografts while heart valves taken from a human–who has donated his/her heart–is called an allograft or, more commonly, a homograft.
