The two main prosthetic valves include mechanical and bioprosthetic (tissue) heart valves. These bovine valves can restore blood flow in the heart which ultimately provides patients a wonderful possibility of returning to their normal lifestyle with a healthy heart. Both bovine and porcine valves have comparable results with regard to the mortality, postoperative functional status and valve durability.
