Nationwide data on transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in Japan are scarce. Using a nationwide inpatient database, we analyzed patients undergoing TAVI (n=8,338) or SAVR (n=16,298) due to aortic stenosis between 2014 and 2017. The annual number of TAVI increased rapidly from 2014 to 2017, particularly in older patients. In-hospital deaths were lower and the length of hospital stay was shorter for patients undergoing TAVI than SAVR. TAVI has been penetrating in Japan as an alternative therapeutic option for aortic stenosis and is associated with acceptable clinical outcomes.
日本全国范围内关于经导管主动脉瓣植入术（TAVI）和外科主动脉瓣置换术（SAVR）的数据稀缺。我们利用全国住院患者数据库，分析了2014年至2017年间因主动脉瓣狭窄接受TAVI（n = 8338）或SAVR（n = 16298）的患者。2014年至2017年，TAVI的年度手术量迅速增加，尤其是在老年患者中。与接受SAVR的患者相比，接受TAVI的患者住院死亡率更低，住院时间更短。TAVI作为主动脉瓣狭窄的一种替代治疗选择，已在日本得到普及，并具有可接受的临床疗效。
