Background: Transcatheter aortic valve replacement (TAVR) is a well-established therapeutic strategy in high-risk patients with severe aortic stenosis. The aim of this study was to analyze the prognostic value of the fragmented QRS morphology (fQRS) on 12-lead electrocardiography (ECG) for predicting 2-year mortality in patients who underwent TAVR. Methods: A total of 272 patients (median age; 84 years, 68.4% female) undergoing the TAVR approached from the femoral artery between 2016 and 2020 were included in this retrospective cohort study. Patients were assigned into two groups based on the presence or absence of fQRS on 12-lead ECG before the procedures. Independent predictors of 2-year mortality were evaluated using Cox regression and Kaplan-Meier survival analysis. Results: During the study period, in total, 2.. Read More»
