Detailed explanation-1: -Aortic valve repair involves a surgical procedure during which the cardiac surgeon may need to trim, reshape or rebuild your diseased valve. During valve repair surgery, a ring is placed at the base of the heart valve to provide added support to the repaired valve. This procedure is referred to as an annuloplasty.
Detailed explanation-2: -During your mitral valve repair you will be given general anesthesia.
Detailed explanation-3: -Tissue heart valve replacements, also known as biological or bioprosthetic valves, are harvested from pigs (porcine heart valves) or constructed from the tissue sac (the pericardium) surrounding the heart of a cow (bovine).
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.
