Although transcatheter aortic valve implantation (TAVI) is still currently guided by transesophageal echocardiography (TEE) in a considerable number of hospitals, exclusive angiographic (Angio) guidance seems a reasonable approach in this setting. To date, however, no studies have directly compared the outcomes of TAVI according to the imaging modality used for procedural guidance. We, therefore, used data from a large multicenter data repository to compare the outcomes of TAVI guided exclusively by Angio and ATEE. All consecutive patients with severe aortic stenosis who underwent TAVI with the CoreValve Revalving System (CRS) in 9 Italian centers from September 2007 to March 2014, dichotomized according to the imaging support used to guide the procedure (ATEE and Angio), were included. Thirty-day and 12-month clinical outcomes were evaluated. Propensity matching analysis was performed to adjust for baseline differences. A total of 625 patients were included (256 and 369 patients were included in the ATEE and Angio groups, respectively). Patients from the ATEE more frequently underwent TAVI under general anesthesia compared with Angio group (37.9% vs 22.8%, respectively, p
