Transcatheter aortic valve implantation (TAVI) is the treatment of choice among patients with symptomatic severe aortic stenosis (AS) deemed inoperable and a valuable alternative to surgical aortic valve replacement for high-risk surgical patients. Over the years, this procedure proved to be relatively safe, but despite this complications may occur. When performing TAVI, the most frequent complications are represented by peripheral vascular complications and bleeding involving the access site. Trans-femoral (TF) route is the preferred access site and device evolution has made it possible to reduce in size sheaths and delivery systems from the initial 22- to 24-Fr of the first generation TF devices, progressively down to 18-Fr and then to 16-14-Fr with the latest generations of prostheses, with a required minimal lumen diameter (MLD) of 5.5 mm. The more vascular-friendly TF-TAVI devices, not only have made it possible to patients with small arteries to be treated with this procedure, but also have markedly reduced vascular complications.
