Evaluation of the Remodeling of the Tricuspid Annulus and Right Heart in Persistent Atrial Fibrillation Patients With or Without Radiofrequency Ablation via Three-Dimensional Echocardiography.

ABSTRACT:

Background

Atrial fibrillation (AF) is linked to tricuspid annulus (TA) and right heart (RH) remodeling. Despite advances in catheter ablation, data regarding its structural impact on the TA and RH chambers remain limited. Therefore, the impact of radiofrequency ablation (RFA) on TA and RH remodeling in persistent AF patients is less clear. Furthermore, the potential of three-dimensional echocardiography (3DE) for evaluating TA and RH remodeling following RFA requires further exploration. This study aimed to characterize TA and RH geometry and function in persistent AF patients before and after RFA via 3DE.

Methods

The 90 subjects included in this study were divided into three groups: the persistent AF group (n = 30); persistent AF patients who underwent successful RFA with
