Abstract | OBJECTIVE: METHODS: The medical records of 51 consecutive patients (aged 55.8 ± 12.9 years, 25 male) who underwent tricuspid valve surgery at the Asan Medical Center between September 1996 and July 2010 were evaluated retrospectively. All patients had severe isolated tricuspid regurgitation but no significant left-sided cardiac disease or history of heart surgery. RESULTS: Tricuspid valve repair (n = 37, 72.5%) or replacement (n = 14, 27.5%) was performed. Replacement involved mechanical (n = 4) or bioprosthetic valves (n = 10). One early death occurred (2.0%). During a median follow-up period of 47.4 months (interquartile range, 10.4-61.4 months), 9 late deaths, 3 readmissions for congestive heart failure, 2 heart transplantations, and 1 tricuspid valve reoperation occurred. Overall and event-free survivals at 5 years were 83.5% ± 5.4% and 77.3% ± 6.1%, respectively. In the multivariable Cox regression analysis, preoperative hemoglobin (P = .045), serum bilirubin (P = .008), estimated glomerular filtration rate (P = .045), and systolic right ventricular dimension (P = .047) were significant and independent determinants of clinical outcome. On serial echocardiographic evaluations (median follow-up period, 28.5 months; interquartile range, 18.9-68.7 months), moderate-to-severe tricuspid regurgitation was detected in 21 patients (41%). Severe tricuspid regurgitation after tricuspid valve repair or bioprosthetic valve replacement was a significant predictor of poor event-free survival, even after adjustment for preoperative risk factors (P = .036).
