Mitral valvuloplasty is a surgical procedure aimed at correcting issues with the mitral valve, which is situated between the left atrium and the left ventricle of the heart. This procedure is primarily indicated for patients suffering from mitral valve prolapse and regurgitation. Mitral valve prolapse occurs when the valve leaflets bulge upward into the left atrium during the contraction of the left ventricle, leading to improper closure of the valve. As a result, blood can leak back into the left atrium, a condition known as regurgitation. The surgical approach typically involves exposing the heart through a median sternotomy or a right anterolateral thoracotomy, allowing access to the mitral valve. During the procedure, cardiopulmonary bypass is established to maintain circulation and oxygenation of the blood while the heart is temporarily stopped. The surgical team initiates cardioplegia to protect the heart muscle during the operation. An incision is made in the left atrium to expose the mitral valve, and the specific repair technique employed will depend on the nature and severity of the valve's damage or malformation. Various methods, such as annuloplasty or leaflet repair, may be utilized to restore the valve's function and integrity, ensuring that it closes properly and prevents regurgitation.
