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\u2010dimensional 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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      The 90 subjects included in this study were divided into three groups: the persistent AF group (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a030); persistent AF patients who underwent successful RFA with sinus rhythm maintenance at the 3\u2010month follow\u2010up were assigned to the RFA group (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a030); and the control group (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a030). 3DE datasets were analyzed to measure TA and RH geometry and function via Tomtec 3D echocardiography analysis software.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared with the AF group, the RFA group presented shorter linear dimensions of the right atrium (RA) (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05).
