Calcific aortic valve stenosis is the most common valvular heart disease in developed countries. Without surgery, the prognosis is extremely dismal. Therefore there is general agreement that surgical aortic valve replacement should be offered to patients with symptomatic severe aortic valve stenosis. However, surgery is denied to approx. 30-40% of elderly patients with severe, symptomatic aortic stenosis due to high perioperative risk. Transcatheter aortic valve implantation (TAVI) is a novel and effective procedure which provides a promising treatment option for some of these patients. This review focuses on TAVI systems, the patients who would benefit from TAVI, and the advantages and disadvantages of the procedure.
钙化性主动脉瓣狭窄是发达国家最常见的瓣膜性心脏病。如果不进行手术，预后极差。因此，一般认为有症状的重度主动脉瓣狭窄患者应接受主动脉瓣置换手术。然而，由于围手术期风险高，约 30-40%的老年重度、有症状的主动脉瓣狭窄患者被拒绝手术。经导管主动脉瓣植入术（TAVI）是一种新颖而有效的方法，为其中一些患者提供了有前途的治疗选择。本文综述了 TAVI 系统、可从 TAVI 中获益的患者以及该手术的优缺点。
