Heart valve dilatation

The role of the membrane in the heart's never-ending blood circulation is common and critical: the valve is equivalent to the gatekeeper, preventing blood from returning to the ventricle that has just left. Between the atrium and ventricle, between the ventricle and the blood vessels leaving the ventricle, there are valves. After the blood has flowed, the valve will close, making the heartbeat we hear on TV. The most common valve problem is mitral valve prolapse.
