Aortic Surgery Transcatheter Aortic Valve Replacement

Transcatheter Aortic Valve Replacement The Edwards Sapien transcatheter aortic heart valve integrates balloon-expandable stent technology with a replacement tissue heart valve. Columbia was one of the first institutions in the U.S. to conduct percutaneous transcatheter aortic valve replacement, in 2006. We are currently designing methods to utilize similar devices to create a transcatheter aortic root replacement.

During the procedure, a catheter is advanced to the aortic valve, either through the femoral artery or through a small chest incision and through the left ventricle. Once the catheter is in place, a tissue valve with metal stent scaffolding is positioned and deployed. X-ray guidance provides indirect visualization. The force of the expanding stent anchors the new valve in place, completely avoiding the need for sutures, cardiopulmonary bypass, open surgery—and their associated effects.
