Abstract
BACKGROUND: The implantation of rapid-deployment aortic valves may interfere with the conduction system of the heart. This study evaluates the occurrence and predictive factors of conduction anomalies in patients undergoing surgical aortic valve replacement (SAVR) with a rapid-deployment balloon-expandable bioprosthesis in a single-center, real-world experience. METHODS: Between May 2010 and April 2019, 700 consecutive patients were included in a prospective, ongoing database with a longitudinal follow-up preoperatively, at discharge, and at 3 months, 1 year, 3 years, and 5 years postoperatively. Thirty-seven patients (5.3%) had a permanent pacemaker at baseline and were excluded from further analysis, leaving 663 patients for analysis. Assessment of conduction anomalies was performed by electrocardiography (ECG) monitoring and repeated 12-lead ECG during the hospital stay and at postoperative follow-ups. RESULTS: Preoperatively, 126 patients (19.0%) presented with different conduction disturbances. New permanent pacemaker implantation (PPI) occurred in 61 patients during the first 14 days (cumulative incidence, 9.4%). The indication for PPI was complete atrioventricular block in 47 cases (77%). Preoperative conduction anomalies, such as right bundle branch block, as well as operative characteristics (concomitant procedures) were found to be independent predictors for new PPI. One-year survival was 98% in patients with new early PPI and 96% in those without new early PPI (P = .60). CONCLUSIONS: The PPI rate was in the range of previous reports for rapid-deployment prostheses. PPI did not have a significant influence on short- to intermediate-term survival. Case selection with exclusion of patients presenting with baseline conduction disturbances may decrease the rate of new PPIs after SAVR with rapid-deployment balloon-expandable bioprostheses.
