Detailed explanation-1: -Cow Valve Replacement Surgery: Transcatheter Aortic Valve Replacement (TAVR) During a TAVR procedure, the surgeon inserts a pencil-thin tube called a sheath into a femoral artery in the leg. Through that sheath, the surgeon uses image guidance to send a balloon catheter through the artery to the aortic valve.
Detailed explanation-2: -Mechanical valves are made from carbon and metal. Tissue (biological or bioprosthetic) valves are usually made from pig or cow tissue, or sometimes from human tissue (in which case they may be called homograft valves), that has been treated to make sure it is not rejected by the body.
Detailed explanation-3: -In conclusion, the bovine valve is superior in its complication and haemodynamic profiles. Both bovine and porcine valves have comparable results with regard to the mortality, postoperative functional status and valve durability.
