Valvuloplasty is a procedure to repair a heart valve that has a narrowed opening that reduces blood flow to the valve. The procedure is done to improve the blood flow through the heart valve and reduce your symptoms.

In a valvuloplasty, a catheter is inserted with a balloon on the tip into an artery in your arm or groin. Live imaging is used to help guide the catheter to the narrowed valve in your heart. Once there, the balloon is inflated and this widens the opening of the valve and separates the valve flaps. The balloon is then deflated, and the catheter and balloon are removed.
