This study was performed to identify echocardiographic parameters related to postoperative clinical outcome in patients who undergo surgery for severe tricuspid regurgitation after mitral valve surgery. Eighteen patients (2 men, 16 women; mean age 58 years) were prospectively enrolled. Echocardiographic examinations were performed before and 15 ± 7 months after surgery. Favorable postoperative clinical outcome was defined as an improvement of ≥1 in New York Heart Association functional class or a >25% increase in respiratory variation of inferior vena cava diameter. Operative mortality was 11% (2 of 18). Of the 16 survivors, 9 (56%) achieved favorable postoperative clinical outcomes. Only systolic tricuspid annulus velocity (S′T) was found to be associated with postoperative clinical outcome (favorable vs unfavorable postoperative clinical outcome 12.9 ± 2.1 vs 9.7 ± 1.7 cm/s, p <0.05). For S′T <9.5 cm/s, the sensitivity, specificity, and positive and negative predictive values for predicting an unfavorable postoperative clinical outcome were 67%, 100%, 100%, and 75%, respectively. In conclusion, ST′ can predict postoperative clinical outcomes in these patients.
