Since the 1960s, several trials have described the implantation of aortic valves using transcatheter techniques. Since 1992, with the development of metallic stents, the combination of balloon-expandable metallic stent and pericardial valve (stent-valve) has become a potentially groundbreaking approach. The first implantation of an aortic stent-valve in a patient with severe calcific aortic stenosis was demonstrated in 2002. Since then, transcatheter aortic valve implantation (TAVI) has been under active investigation. Since 1996, we also have been trying to develop a novel aortic stent-valve using our original metallic stent. In this feature article, knowledge obtained through our preliminary experiments was described.
