Feasibility and Safety of TAVI Without Predilatation: an Observational All Comers Study

The procedure is performed via transfemoral or transcaprotid access; Patients were confirmed to be eligible for TAVR by a multidisciplinary heart team including at least an interventional cardiologist, a cardiothoracic surgeon and an anesthetist. All TAVR implantation procedures were performed with the Edwards SAPIEN 3 THV or the MEDTRONIC CoreValve EVOLUT . For all patients, both vascular access and aortic valve were evaluated before the procedure by multislice computerized tomographic angiography (MSCT) of the entire aorta using vascular windows settings. The prosthesis and the vascular access were left to the discretion of the operating team. Transfemoral access was the first choice when possible. All TAVR procedures were performed in the same hybrid room (in Montpellier University Hospital), Most TAVR were performed under sedation or general anesthesia using mild low profile 14-16 French delivery systems and using percutaneous or surgical vascular access.
