Abstract 17539: Conventional vs. Transcatheter Aortic Valve Replacement - Propensity Score Adjusted Comparison of 3,751 Unselected Patients

Background and Hypothesis: Transcatheter aortic valve replacement (TAVR) is an established method in high-risk patients. Two aspects of this procedure are currently under discussion: 1.) Do the data acquired from randomized studies and registers justify expansion of the procedure to include younger and healthier patients? 2.) Is the transfemoral approach superior to the transapical approach with regard to mortality and periprocedural complications? Against this background we examined the mortality and morbidity of all patients who received an isolated conventional, transapical or transfemoral aortic valve replacement in accordance with the criteria of the Valve Academic Research Consortium (VARC)-2. Methods: A prospective register was taken from a single center recording all conventional (CONV, n=2,881), transapical (TAVR-TA, n=363) and transfemoral (TAVR-TF, n=570) aortic valve implantations during the period from 07/2009 to 10/2014. Using propensity score (PS) matching, first CONV and TAVRall (TA+TF) an...
