Heart valve surgery. Image 14 of 24. Diseased heart valve removed during valve replacement surgery. This is heart valve replacement surgery. An artificial (prosthetic) valve will replace the diseased valve. There are four valves in the human heart,all of which prevent the backflow of blood. Damage to the valves can lead to malfunctioning of the heart and death. If a valve cannot be repaired it must be replaced. For a sequence showing the operation,see images M560/494 to M560/517 | |
