Abstract:
A rare case of mechanical prosthetic valve dysfunction in mitral position. The mechanical valve opened once every two cardiac cycles. We also found the opening time of the mechanical valve in aortic positions was long and short alternately because of the Left ventricular volume changed every cardiac cycles.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
