Aortic stenosis is a prevalent disease with poor prognosis if left untreated. Transcatheter aortic valve implantation (TAVI) is an emerging treatment for patients at high risk for surgery. We describe a patient with no suitable peripheral access due to peripheral vascular disease (PVD) for TAVI. Direct aortic approach via an 18-Fr sheath inserted into the ascending aorta was successfully performed with a 29-mm CoreValve implanted. Direct aortic approach is feasible for TAVI in patients with severe PVD without good peripheral access.
主动脉瓣狭窄是一种常见疾病，若不治疗，预后较差。经导管主动脉瓣植入术（TAVI）是一种针对手术高危患者的新兴治疗方法。我们描述了一名因外周血管疾病（PVD）而无合适外周入路进行TAVI的患者。通过插入升主动脉的18F鞘管采用直接主动脉入路成功实施手术，并植入了29mm的CoreValve。对于外周入路不佳的严重PVD患者，直接主动脉入路用于TAVI是可行的。
