Secondary endpoints included other in-hospital clinical events, 30-day all-cause mortality, and an assessment of the time trend of this registry. Methods: All consecutive patients included in the Spanish TAVI registry were analyzed. In this time-based analysis, the population was been divided into patients treated before 2014 (cohort A: 2009-2013) and patients treated between 2014 and 2018 (cohort B). Results: From August 2007 to June 2018, 7180 patients were included. The mean age was 81.2 +/- 6.5 years and 53% were women. The logistic EuroSCORE was 12% (8-20). Transfemoral access was used in 89%. In-hospital and 30-day all-cause mortality was 4.7% and 5.7%, respectively. On the time-based analyses during the hospital stay, the rate of myocardial infarction, stroke, need for pacemakers, tamponade, coronary obstruction, and vascular complications was similar between both groups. However, cohort B showed less need for conversion to surgery and malapposition of the valve. Also, the implant success rate increased from 93% to 96% (PenAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Transcatheter Treatment of the Aortic ValveRecordsSevere Aortic Stenosisresearch articleopen access10.24875/RECICE.M200001042604-7276https://doi.org/10.24875/recice.m20000104908946200007
