Transcatheter Mitral Valve In Valve

Mitral valve in valve is a minimally invasive transcatheter mitral valve replacement (TMVR) procedure for patients who have had previous open heart valve surgery to replace the mitral valve with a bioprosthetic/tissue valve and the tissue valve is now failing. Instead of the failing mitral tissue valve being replaced during another open heart mitral valve surgery, the failing mitral tissue valve is replaced by placing a TAVR valve inside the failing mitral tissue valve.

TMVR techniques
During TMVR, an interventional cardiologist and/or a cardiac surgeon inserts a tube (catheter) through an artery in the body. The TMVR valve is compressed and fed through the catheter until it reaches the failing mitral tissue valve. A balloon expands or wedges the TMVR valve within the failing mitral tissue valve and the catheter is removed. The TMVR valve remains in place pushing the failing mitral tissue valve out of the way, allowing the TMVR valve to take over the job of regulating blood flow.

Transcatheter techniques like those used in TMVR allow the procedure to be performed while the patient’s heart is still beating, eliminating the need for a “bypass” machine and its associated risks.
