Mitral valve repair

Sunnybrook’s Schulich Heart Program uses advanced valve repair and replacement technology and innovative thinking to provide patients with new ways to get their lives back, even when the most challenging valves fail.

Your heart has four valves that act like one-way doors: they let blood flow in and out of different sections of your heart. The mitral valve is between the upper left chamber (left atrium) and the lower left chamber (left ventricle) of your heart. If the valve doesn’t close tightly, blood can leak backward into the left atrium. This is called mitral regurgitation.

Transcatheter Mitral Valve Repair is a procedure that repairs your mitral valve without open heart surgery. Sunnybrook was the first in Toronto to perform the procedure in 2011.

How it works

In the minimally-invasive procedure, a specialized clip called a MitraClip is guided by a catheter through a vein in the upper leg to the right side of the heart and then to the left atrium. Using imaging technology, the clip is positioned and secured to the mitral valve where it is leaking. One or more clips may be used to fix the backwards blood flow. The catheter is removed and pressure is applied to the puncture site. The procedure works immediately.
