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±0.15m2. 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±0.12cm2 at baseline to 1.46±0.29cm2 after the procedure (P<0.001), and the mean aortic transvalvular pressure gradient decreased from 51.0±15.6 at baseline to 11.2±3.6 after the procedure (P<0.001). The 30-day mortality and combined safety endpoint rates were 0% and 4.8%, respectively. All patients achieved New York Heart Association functional class I or II at 30 days. Conclusions: Early outcome of TAVI with the Edwards-SAPIEN XT valve via the transiliofemoral approach at Kurashiki Central Hospital is satisfactory for patients who are ineligible or at high risk for SAVR.  (Circ J 2014; 78: 1357–1363)<br>
