Early and Late Outcomes of Isolated Tricuspid Valve Surgery Following Valvular Surgery

Purpose: Isolated tricuspid valve surgery (TVS) following valvular surgery has been still challenging. We reviewed our experience to determine early and late outcomes. Methods: We retrospectively analyzed 14 patients (mean age, 57.0 ± 17.8 years old) who underwent isolated TVS after valvular surgery between January 1990 and December 2010. The causes of isolated TVS were structural valve deterioration (SVD) (n = 5) and symptomatic severe tricuspid regurgitation (n = 9). The mean follow-up period was 6.4 ± 5.9 years. Results: At redo, seven patients underwent tricuspid valve replacement (TVR) using a bioprosthesis and the remaining underwent tricuspid valve repair (TVP). Early mortality rate was 7.1% (1/14). Survival rates at 5 and 10 years were 68.8% ± 13.1% and 68.8% ± 13.1%, respectively. Three deaths (two for heart failure and one for cerebral hemorrhage) were observed. Freedom from valve-related events was 58.3% ± 14.2% at 2 and 48.6% ± 14.8% at 5 years. Six events were observed (five for heart failure and one for cerebral hemorrhage). There was no statistically significant difference between TVP and TVR as to freedom from valve-related events (log-rank p = 0.3655). Conclusions: Early and late outcomes of isolated TVS after valvular surgery seem to be satisfactory. Special attention should be paid to heart failure following TVP.
