A balloon valvotomy is a highly recommended treatment for mitral valve stenosis, a condition where the mitral valve becomes narrowed, hindering proper blood flow through the heart. The procedure aims to widen the mitral valve, facilitating smoother blood flow.

A balloon valvotomy is a minimally invasive technique. A doctor utilizes a thin, flexible tube called a catheter, which is inserted through an artery in the groin or arm and carefully guided into the heart. Once the catheter reaches the narrowed mitral valve, a balloon device situated at the tip of the catheter is swiftly inflated. This inflation causes the fused or narrowed leaflets of the mitral valve to separate and stretch, enlarging the opening and allowing improved blood flow from the left atrium to the left ventricle.

Compared to open-heart surgeries like commissurotomy or valve replacement, balloon valvotomy is a catheter-based procedure and carries a lower risk of complications and mortality.

However, it is important to note that after 3 to 7 years, approximately 35 to 50 out of 100 individuals may require another procedure or surgery. Despite this, about 80 to 95 out of 100 individuals who undergo balloon valvotomy experience successful outcomes and almost immediate relief from symptoms.
