A snare maneuver to reposition self-expandable aortic valve after transcatheter replacement of surgically implanted valve.

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.
