Permanent pacemaker implantation after transcatheter self-expanding aortic valve replacement: data from a single-center registry

Background. Transcatheter aortic valve replacement is a safe and effective procedure in patients with severe aortic stenosis who are at high surgical risk. One of the most commonly diagnosed complications after transcatheter aortic valve replacement is postoperative complete heart block, requiring in most cases the permanent pacemaker implantation. Aim. The study aims to identify independent prognostic factors of permanent pacemaker implantation after transcatheter aortic valve replacement. Methods. This retrospective study included 336 patients who underwent transcatheter self-expanding aortic valve replacement between 2015 and 2021. 28 patients (8.3%) after procedure required the permanent pacemaker implantation. Patients with a previously implanted permanent pacemaker, surgical aortic valve replacement, transcatheter aortic valve replacement in history and patients after conversion of endovascular intervention to surgical replacement were excluded from the study. Results. The mean age of patients was 75.4 ± 7.4 years.
