ObjectiveTo discuss the feasibility about the using of transcatheter aortic valve implantation (TAVI) in severe aortic valve stenosis chinese patients, then to make more exploration and accumulate enough experience. MethodsWe selected 10 out-patients with severe aortic valve stenosis and calcified with 9 males and 1 females at age of 76.4 (65-81) years in our hospital from January 2011 to March 2014. All the patients can't tolerate traditional open surgery through preoperative evaluation. So we chose the Sepian TX system, balloon dilated transcatheter aortic valve, to treat them via transfemoral approach. ResultsTen patients accomplished TAVI successfully. One patient was assisted by the left-ventricular puncture. No complication occurred. The function of aortic valve after TAVI improved significantly. The hospital stay time was 3-5 days. The patients were followed up for 3-34 months. One patient died of pulmonary cancer during the following-up. ConclusionTranscatheter balloon dilated aortic valve replacement can be used in chinese severe aortic valve stenosis patient, but more accurate preoperative preparation, evaluation, and operation are needed.
