Abstract:
Transcatheter aortic-valve implantation is rapidly emerging as an effective, safe, and sustainable alternative for a specific subset of high-surgical risk and/or inoperable patients with severe aortic stenosis. However, technical challenges remain for this relatively new procedure, not the least mal-positioning of the transcatheter prosthesis resulting in acute aortic regurgitation. We report a case of deep implantation of a CoreValve prosthesis that was inadvertently pulled out of the aortic annulus during repositioning. The patient received a second sequential CoreValve successfully.
