Detailed explanation-1: -Tissue valves, also known as biological or bioprosthetic valves, are composed of animal or human tissue.
Detailed explanation-2: -Artificial heart valves are often known as mechanical heart valves and made from metallic alloys or plastic materials. In bioprosthetic heart valves, the valve tissue is typically from an animal species and mounted on a frame, known as a bioprosthesis.
Detailed explanation-3: -Bioprosthetic valves are generally made of either bovine pericardium or porcine aortic valves, but may also be produced from equine or porcine pericardium. The advantage of these bioprosthetic valves is that they do not require life-long anticoagulation.
Detailed explanation-4: -Bioprosthetic heart valves (BHVs) are constructed from porcine heart valves or bovine pericardium preserved with glutaraldehyde.
