Mitral balloon valvuloplasty is a procedure used to treat mitral valve stenosis. In this procedure, a thin balloon catheter is inserted through the groin or arm and directed to the mitral valve in the heart. The balloon is inflated at the valve site to widen it. This increases the valve's opening, improving blood flow through the heart and alleviating symptoms such as shortness of breath. The procedure is typically performed using a minimally invasive approach, which shortens the recovery time for patients.
