Pacemaker-associated Right Heart Failure: An Under-recognized Problem

David L. Fischman¹

Abstract: Patients presenting with right-sided heart failure represent a clinical challenge with numerous potential etiologies and limited treatment options. This report presents a challenging case involving right-sided heart failure due to persistent tricuspid regurgitation (TR) exacerbated by the placement of a right ventricular (RV) pacing lead after mitral valve repair. Ultimately, lead extraction resulted in decreased TR severity, improvement in RV function, and resolution of heart failure symptoms, highlighting th… Show more

Aims The effect of right ventricular (RV) pacing on left ventricular (LV) function has been extensively evaluated, but the effect on RV function per se has not been evaluated systematically. We aimed to assess the effect of dual chamber pacemaker on RV function. Methods and Results All consecutive patients undergoing dual chamber pacemaker from January 2018 to March 2019 for AV block with a structurally normal heart were included. They underwent pre‐procedure detailed echocardiography (including three‐dimensional [3D] RV ejection fraction [RVEF]), a screening echocardiogram 2 days after pacemaker implantation and again a detailed echocardiogram at 6‐month follow‐up. We compared the baseline echocardiographic RV parameters with those 6 months after the pacemaker implantation. A total of 60 patients underwent successful pacemaker implantation. At 6 months, most of the patients were pacemaker dependent with pacing percentage of 98.9% ± 2.4%; there was a significant increase in TR and a mean drop in RVEF by 2.8 ± 5%, with 23 (38.3%) having at least a 5% decrease in RVEF. The drop in RVEF positively correlated with TR vena contracta at 6 months but did not correlate with pulmonary artery systolic pressure at 6 months. Conclusion Our study shows the presence of demonstrable RV dysfunction as early as 6 months in a majority of patients who have undergone pacemaker implantation.
