The last years, various large randomized studies have demonstrated the benefit of TAVI (transcatheter aortic valve implantation) over medical therapy or over conventional surgical treatment in inoperable or very high risk patients with symptomatic severe aortic stenosis. More recently, new data has also shown that among patients at intermediate risk, TAVI is at least as beneficial as surgical valve replacement. In this article, we will focus on the new recommendations of the European society of cardiology but also on issues that remain open.
