Transcatheter aortic valve implantation (TAVI) has become first-line treatment for severe aortic valve stenosis in patients with moderate, high or prohibitive surgical risk. However, access site complications may occur more frequently in extreme body mass index (BMI) categories. The aim of this study was to describe the features and outcomes of patients undergoing TAVI in a comprehensive Italian prospective clinical registry, focusing on BMI classes. ⋯ Irrespective of BMI class, TAVI is associated with favorable outcomes in surgical high-risk risk patients, with the notable exclusion of permanent pacemaker implantation, which is significantly more common in obese subjects.
