title: Left ventricular outflow tract embolization and balloon assisted recapture of a SAPIEN XT prosthesis during transcatheter aortic valve replacement.
abstract: Transcatheter aortic valve replacement has emerged within the last decade as a proven alternative therapy in patients with severe aortic stenosis and prohibitive surgical risk. Despite rapidly evolving device technology and growing operator experience, peri-procedural complications are still relatively common. We present a case in which a SAPIEN XT prosthetic valve embolized into the left ventricular outflow tract. This was followed by balloon assisted recapture and subsequent successful implantation of the valve across the aortic annulus without significant hemodynamic compromise or surgical intervention. © 2015 Wiley Periodicals, Inc.
