Mechanical heart valve surgery involves the replacement of the defective valve with a substitute made of metallic alloys and plastics. Most, but not all, bioprostheses contain a network of wires, the stents, that provide support to the commissures of the porcine aortic valve or of the constructed aortic valve made of pericardial tissue. This means that patients with mechanical heart valves are less likely to need a reoperation or repeat valve procedure.
