Aims: This study aimed to compare the clinical outcomes of patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) via a percutaneous or surgical cut-down approach. Methods and results: Between October 2013 and July 2015, 586 patients underwent transfemoral TAVI according to the Optimized CathEter vAlvular iNtervention (OCEAN)-TAVI registry (percutaneous approach, n=305; surgical cut-down approach, n=281). After propensity matching, 166 patients underwent transfemoral TAVI via each approach. Major vascular complications, as defined per the Valve Academic Research Consortium-2 criteria, were found less frequently in patients who underwent a percutaneous approach (15.1% vs. 27.1%, p<0.01), and femoral artery injuries requiring surgical repair were mostly the result of a closure device failure (seven cases, 4.2%). In these patients, major bleeding was less (7.2% vs. 16.9%, p=0.01) and blood transfusion less frequent (21.1% vs. 38.0%, p<0.01); therefore, cases of acute kidney injury (AKI) were rare (6.0% vs. 15.1%, p<0.01). Conclusions: Transfemoral TAVI using the percutaneous approach proved safe and feasible and resulted in fewer major vascular complications, bleeding and AKI events compared to the surgical cut-down approach.
