Within 10 years after transcatheter aortic valve implantation (TAVI) was first accomplished for treatment of calcified aortic stenosis, this new technology has rapidly evolved to become clinical routine. Today it may be considered standard treatment for inoperable patients with superior outcomes compared to best medical therapy. Furthermore, it represents an alternative therapeutic option compared to surgical aortic valve replacement in high-risk patients. According to current international guidelines and expert consensus statements, TAVI should be performed as a joint effort by an interdisciplinary heart team to ensure input from multiple skill sets for optimal patient outcome. Major safety concerns include neurologic complications, acute kidney injury, access site complications, procedure-related conduction disturbances, paravalvular leakage valve durability. At present, only one device for transapical TAVI is in widespread clinical use: the Edwards Sapien transcatheter valve (Edwards Lifesciences, Irvine, CA, USA). Recently, however, a number of second generation devices for transapical TAVI have been developed in order to address some of the limitations of first generation valves. In this paper, current data on second generation devices for transapical TAVI will be reviewed and ongoing trials discussed.
