Transcatheter mitral valve repair (TMVR) is a procedure to help the mitral valve close better. The mitral valve separates the left upper chamber (left atrium) and left lower chamber (left ventricle) of the heart. It is formed from two downward-facing flaps. The valve's job is to make sure the blood flows in only one direction, from the upper to the lower chamber.
Mitral valve regurgitation happens when the valve doesn't close all the way. Blood leaks backward, or regurgitates, into the upper chamber of the heart. This causes the heart to work harder to pump blood.
In TMVR, one or more small clips hold parts of the valve flaps together. These help the valve close better and reduce the amount of blood that leaks into the upper chamber. A TMVR may help reduce symptoms like shortness of breath and tiredness.
You will likely be asleep for the procedure. Your doctor makes a small cut in your groin. A thin flexible tube (catheter) with tools inside it is put inside your blood vessel and carefully guided to your heart. Your doctor moves the tip of the catheter to the valve and attaches one or more clips to the valve flaps. These clips remain in your heart.
You may stay in the hospital for up to a few days.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
