The mitral valve is one of the four heart valves and is located between the left atrium and the left ventricle. It opens to allow blood to flow from the left atrium into the left ventricle and closes to prevent blood from flowing backward. When the mitral valve is damaged, it can lead to serious heart conditions such as mitral stenosis (narrowing) or mitral regurgitation (leakage), affecting the heart’s ability to pump blood efficiently.

Mitral valve replacement surgery involves replacing a damaged mitral valve with either a mechanical or biological valve. This procedure is performed to restore normal blood flow through the heart and improve heart function. It is often recommended when the valve cannot be repaired and symptoms become severe.
