Abstract Background The majority of cases significant tricuspid regurgitation (TR) are secondary to annular dilation and leaflet tethering in the context RV remodeling due pressure or volume overload, as seen patients with pulmonary hypertension (primary left-sided heart disease) dilated cardiomyopathies. Secondary TR induced by valve dilatation right atrial is referred functional TR, while caused ventricular TR. In current guidelines, GDMT (Guideline-Directed Medical Therapy) effective for attributable HF reduced LVEF. Normal sinus rhythm should be restored AF-related dilatation. however, AF may also accompany clinical condition. It unknown whether restoring will reduce these patients. Purpose objective this study was investigate degree change after restoration. Methods A retrospective cohort undergoing ablation cardioversion at a single center between 2019 2023 performed. Patients least grade 1 on echocardiography baseline echocardiogram follow-up were included. A-FTR V-FTR defined according latest ACC/AHA guidelines. According mild severe FTR classified if they had fibrillation, left ejection fraction >60%, artery systolic (PASP) <50 mm Hg, no disease, normal-appearing leaflets. who did not meet one three criteria (V-FTR). Results total 88 enrolled. prevalence our 62% (53 patients), 38% group. There difference groups regarding age, gender, NYHA class. 21 underwent DCCV, 67 catheter ablation. similar (%17 vs. %8,6 V-FTR, p= 0.205). preintervention two groups. severity improved significantly from both These outcomes observed DCCV Conclusion restoration TR.Changes interventionGraph changes
