Heart Valve Replacement Surgery
Valve Replacement is a surgery which involves replacement of heart valves with grafts or artificial valves or bio-prosthesis in order to restore normal heart functioning. The bio-prosthesis is a graft made of biological tissue that may be a human tissue (homograft) or tissue from an animal, usually pig(xenograft).

The Procedure of Heart Valve Replacement
The procedure involves separation of breastbone and ribs and the faulty heart valves are traced. The edges of the valves are loosened from the tendons by slicing the edges around the valves and then the faulty valves are removed. The valves are then replaced by the new valves and the patient is taken off the bypass machine. Finally the chest wall is closed.
