Successful catheter ablation of persistent atrial fibrillation is associated with improvement in functional tricuspid regurgitation and right heart reverse remodeling

Atrial fibrillation (AF) is a common disease that changes cardiac morphology, especially in the left atrium (LA). It is now known that certain categories of functional mitral regurgitation (MR) are associated with AF; however, the influence of AF on right cardiac morphology is not fully understood....

Description
Summary:Atrial fibrillation (AF) is a common disease that changes cardiac morphology, especially in the left atrium (LA). It is now known that certain categories of functional mitral regurgitation (MR) are associated with AF; however, the influence of AF on right cardiac morphology is not fully understood. Our aim in this study was to investigate the association between AF and right cardiac morphology. This was a retrospective cohort study of 86 patients with persistent AF without other cardiac disease who underwent catheter ablation (CA). Seventy-one patients had sustained sinus rhythm (SR) (SR Group) and 15 patients had sustained AF (AF Group) during the study period. We compared the changes in the right cardiac dimensions and tricuspid regurgitation (TR) between the groups 12 months after CA. Patients’ baseline echocardiographic assessments revealed that the LA volume index was significantly smaller in the SR group than in the AF group (46.8 ± 11.9 ml/m 2 vs 59.3 ± 12.8 ml/m 2 , respectively; p
