Concomitant Endografting of a Type B Aortic Dissection During Transfemoral Aortic Valve Replacement.

Abstract

An 87-year-old woman with severe aortic stenosis underwent a transfemoral transcatheter aortic valve replacement (TAVR). Intraoperative transesophageal echocardiography demonstrated a well-seated valve with no paravalvular leak; however, a new acute type B aortic dissection was identified. Endografts were delivered through the TAVR sheath and deployed, effectively treating the dissection. The patient did well postoperatively, with imaging at 2 years demonstrating a well-functioning aortic valve and no migration or endoleak of the thoracic endografts. To our knowledge, this is the first report of successful concomitant thoracic endografting during TAVR for the treatment of iatrogenic aortic dissection in this setting.
