Abstract 2868: Long-Term Prognostic Predictors of Isolated Significant Tricuspid Regurgitation

Background: Long-term outcomes of isolated significant tricuspid regurgitation (TR) without significant left-side heart disease remain to be clearly demonstrated. Methods: We enrolled 547 consecutive patients (age: 64 ± 14 years) with isolated significant TR. The patients with atrial septal defect, significant pulmonary or pulmonary vascular disease, right ventricular dysplasia and constrictive pericarditis were excluded. Initial clinical and echocardiographic characteristics and clinical outcomes were analyzed for 5.6 ± 2.1 years. Results: Survival rate was not different between 39 patients who underwent tricuspid valve (TV) surgery and 508 patients who did not (p=0.48). Of 508 patients without TV surgery, 32 patients (6.3%) died with cardiac cause during the follow-up period. Those patients were older (71 ± 16 vs. 64 ± 13 years, p<0.05) and showed initial larger TR jet area (15 ± 7 vs. 12 ± 4 cm2, p<0.05), and higher pulmonary artery systolic pressure (PASP, 46 ± 22 vs. 39 ± 16 mmHg, p<0.05).
