Outcomes of Transcatheter Aortic Valve Replacement in Low-Risk Patients in the United States: A Report From the STS/ACC TVT Registry | Circulation
BACKGROUND: Real-world low-risk transcatheter aortic valve replacement (TAVR) outcomes in the United States have not been assessed comprehensively versus pivotal trials, which is a key component of measuring the quality of clinical technology adoption. METHODS: We identified heart team–designated low-risk patients undergoing TAVR for trileaflet severe, symptomatic aortic stenosis in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Registry, as well as a subset of patients who met low-risk trial inclusion and exclusion criteria, from January 2020 to March 2024. Outcomes (mortality, stroke, new pacemaker, and “alive and well,” defined as alive at 1 year with Kansas City Cardiomyopathy Questionnaire score ≥60 and ≤10-point decrease from baseline) at 30 days and 1 year were assessed. Multivariable models were developed to assess predictors of death within 1 year after TAVR. RESULTS: Among 383 030 patients who underwent TAVR during the study period, 108 40
