Recently, transcatheter aortic valve implantation (TAVI) is attracting increasing attention across the globe. Aortic valve replacement for aortic valve stenosis has commonly achieved safety and excellent durability over a few decades. But this conventional surgery is still extremely invasive for elderly and high-risk patients. So less invasive surgical techniques are necessary, and we believe TAVI serves such a purpose. TAVI was started in 2002, mainly in Europe and Canada, and over 20000 cases have received TAVI worldwide until now. In 2009, we performed the first case of TAVI in Japan, and 22 cases have since received TAVI in our institution. The data of clinical trials are prohibited to be shown to the public, so in this session, we elucidated the results of four TAVI cases (transfemoral: 3, transapical: 1) by clinical research. In addition, several new devices for TAVI have already been launched in US and Europe. I will show you these new devices and discuss the future picture of TAVI.
