Abstract
In this case, we successfully repositioned the transcatheter heart valve (THV) by pulling it with a snare inserted via the right brachial artery. Attempting to pull the THV via the femoral approach was not successful, due to the vector of the pulling force not being coaxial. Changing the direction of the force by switching to an approach from the right brachial artery successfully prevented perivalvular leakage. While there are previous case reports of repositioning an implanted transcatheter valve in a native valve using a gooseneck snare, to our knowledge, this is the first case of successfully repositioning an implanted transcatheter valve in a valve-in-valve procedure using the precise assessment that can be achieved with intra-procedural transesophageal echocardiography. LEARNING OBJECTIVE: Perivalvular leakage (PVL) is a major problem after transcatheter aortic valve replacement. In this case, we experienced PVL after implantation of self-expandable transcatheter heart valve (THV) inside the previously inserted Mosaic bioprosthetic valve. Depth of the implanted valve was too low into left ventricle accessed with transesophageal echocardiogram. It is barely known whether THV in surgical implanted aortic valve could be repositioned using snare maneuver, but we successfully pulled the valve via brachial artery and PVL was controlled.
