Percutaneous Trans-Mitral Commissurotomy (PTMC) / Balloon Mitral Valvotomy (BMV)

Meaning:
Percutaneous Trans-Mitral Commissurotomy (PTMC), also known as Balloon Mitral Valvotomy (BMV), is a minimally invasive catheter-based procedure used to treat mitral valve stenosis. A specially designed balloon is positioned across the narrowed mitral valve and inflated to separate fused valve leaflets, improving blood flow from the left atrium to the left ventricle.

Causes:
Mitral valve stenosis most commonly develops due to rheumatic heart disease and may also result from valve degeneration or calcification. The narrowed valve restricts blood flow, leading to symptoms such as breathlessness, fatigue, palpitations, and reduced exercise tolerance.

Treatments:
PTMC/BMV is performed under imaging guidance to ensure accurate balloon placement and controlled valve opening. The procedure helps relieve obstruction, reduce symptoms, and delay or avoid the need for surgical valve replacement in suitable patients.

Prevention:
Early diagnosis and regular monitoring of mitral valve disease help prevent progression to severe stenosis. Timely treatment of rheumatic fever, appropriate medical management, and routine cardiac follow-up play an important role in maintaining valve health.
