Our aim was to study the influence of baseline ECG parameters, including interatrial block (IAB), in the prognosis of patients treated with transcatheter aortic valve implantation. Methods and Results The BIT (Baseline Interatrial Block and Transcatheter Aortic Valve Implantation) registry included 2527 patients with aortic stenosis treated with transcatheter aortic valve implantation. A centralized analysis of baseline ECGs was performed. Patients were divided into 4 groups: normal P wave duration ( YR 2020 FD 2020-11-03 LK http://hdl.handle.net/10668/16533 UL http://hdl.handle.net/10668/16533 LA en DS RISalud RD Apr 11, 2025
