Transcatheter Aortic Valve In Valve

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

TAVR Techniques

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

Transcatheter techniques like those used in TAVR 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.
