Abstract:
Transcatheter aortic valve implantation is a novel therapeutic approach for high-risk patients with severe symptomatic aortic stenosis. The success rate of this new procedure is high; however, procedural complications can occur and may result in devastating outcomes. Here, we report a case of transfemoral catheter aortic valve implantation using the Edwards SAPIEN valve complicated by severe intravalvular leak due to immobile cusp associated with shock. We treated with a second valve that embolized and deployed in the descending aorta. A third valve was then deployed within the first with elimination of aortic regurgitation and immediate hemodynamic improvement.
