This study looking at tricuspid regurgitation (TR) after permanent pacemaker implantations and its influence on atrial fibrillation (AF), included 530 patients with dual-chamber permanent pacemakers. Primary outcomes included moderate to severe tricuspid regurgitation and isolated tricuspid regurgitation. Median follow-up was 7.6 years. Multivariable analysis revealed independent predictors of moderate to severe TR, including diabetes, chronic lung disease, pre-existing mild tricuspid regurgitation, peripheral artery disease, moderate to severe aortic regurgitation, and persistent AF. Persistent AF was associated with a higher incidence of moderate to severe TR (21.8% vs. 12.9% vs. 11.6% for persistent AF, paroxysmal AF and without AF, respectively).
