Thirty-Day Outcome of Transcatheter Aortic Valve Implantation With the Edwards SAPIEN XT Prosthesis via the Transiliofemoral Approach

BACKGROUND Few data exist on the results of transcatheter aortic valve implantation (TAVI) via the transfemoral approach in small slightly built Japanese patients with severe aortic stenosis who are ineligible or at high-risk for conventional surgical aortic valve replacement (SAVR). Therefore, the purpose was to investigate the early outcomes of TAVI using the transiliofemoral approach in Japan. METHODS AND RESULTS Between June 2010 and June 2013, 21 consecutive patients (mean age, 81.0 years; 81.0% female) underwent TAVI with Edwards SAPIEN XT valves using the transiliofemoral approach. The mean body surface area was 1.44±0.15m(2). The device success rate was 90.5%. Although 2 patients did not meet the echocardiographic criteria for device success, no failure to deliver and deploy a valve occurred. The mean effective aortic valve area increased from 0.54±0.12cm(2) at baseline to 1.46±0.29cm(2) after the procedure (P
