Transcatheter Treatment of Pure Aortic Regurgitation in a Horizontal Aorta Complicated by Valve Embolization and Aortic Dissection

A 83-year-old female with severe aortic regurgitation (AR) and an horizontal ascending aorta was scheduled for a transcatheter aortic valve replacement. After the complete deployment, a Portico 29 mm valve embolized in the ascending aorta due to the unfavorable anatomy of the anchoring zone. A second Portico 29 mm was successfully implanted using the embolized valve for superior anchoring. The patient died 7 days after the procedure due to a retrograde aortic dissection. This case shows a rare but possible complication that occurs especially in unfavorable and complex aortic anatomies. (c) 2019 Elsevier Inc. All rights reserved.
