Popis: Aims Patients with severe aortic stenosis (AS) can be considered for treatment with either transcatheter (TAVR) or surgical aortic valve replacement (SAVR). The purpose of this study was to compare left ventricular (LV) remodeling in patients with AS after treatment with TAVR or SAVR. Methods and results This is an echocardiographic substudy of the NOTION trial, a randomized all-comers trial comparing TAVR with SAVR in patients above 70 years of age. Transthoracic echocardiograms were performed at baseline, 3 and 12 months after TAVR and SAVR. About 232 patients were included in the study, 120 were randomized to TAVR and 112 to SAVR. From baseline to 12 months post-procedure, aortic valve area (AVA) increased in both groups, but with a larger increase in the TAVR group (0.65 ± 0.04 cm2 vs. 1.02 ± 0.05 cm2 for SAVR and TAVR group, P
