Abstract:
Objective: To explore the occurrence rate of permanent pacemaker implantation (PPI) with relevant risk factors in patients after mechanical aortic valve replacement. Methods: A total of 1986 consecutive patients with mechanical aortic valve replacement were enrolled in this study. According to PPI conduction caused by severe arrhythmia , the patients were divided into 2 groups: PPI group,n=61 including 27 male with the average age of (53.6 ± 9.03) years and Non-PPI group,n=1925. The median follow-up time was (4.47 ± 4.36) years after valve replacement. Results: The patients in PPI group were with the elder age and higher ratio of pre-existing atrial ifbrillation (AF) than those in Non-PPI group,P<0.05. The overall PPI occurrence rate was 3.07% after valve replacement and the short term incidence rate (within 30 days) was 0.55%, midterm (from 30 day to 1 year) was 0.03%, long term (>1 year) was 2.22%. For PPI indications, there were 70.5% patients with high degree A-V block including 30 of AF combining long intervals, 12 of high degree A-V block, 1 of complete left bundle branch block (LBBB) and 14.8% patients with sick sinus syndrome/sinus arrest/ sinus bradycardia. Conclusion: PPI incidence was at a relative low level, the long term occurrence rate was higher than both short term and midterm; elder age, pre-existing AF could be the high risk factors for PPI requirement, and the major PPI indication was high degree AV block in clinical practice.
