Abstract 13085: Isolated Tricuspid Valve Surgery: Failure of Its Principle? Long-Term Outcome Analysis
Introduction: Isolated tricuspid valve (TV) surgery for acquired TV disease is high-risk surgery and the decision to operate is still controversial. We describe a single-centre experience with isolated TV surgery and our long-term analysis for adverse outcome.
Methods: A retrospective analysis of 62 consecutive patients who underwent isolated TV surgery for acquired TV disease between 2002 and 2014 has been performed. Associated cardiac procedures and congenital TV disease were exclusion criteria. The Kaplan-Meier, Univariate and Cox regression analysis were respectively used to evaluate mortality and identify risk factors at long-term follow-up. The Duke Activity Status Index (DASI) questionnaire, to measure the functional status related to daily living, has been used to assess the survivors’ quality of life.
Results: Mean patient age was 60.2±18.9 years, 38% were male and the average log EuroSCORE was 16.8%±15.9%. TV repair was performed in 38 cases (61%), replacement in the remainder and 38% were reoperations. 30-day mortality was 15% (n=9) , similar for repair and replacement. Follow-up (median=35.7 months, range=0.1-150) was 100% complete. Survival at 1, 5 and 10 years was 79.5%±5%, 69.8%±6% and 53.5%±9.7% respectively. Sinus rhythm, NYHA class < III, age < 60 years were identified as independent predictors of survival at long-term follow-up. Furthermore, we found that survivors with a lower pre-operative NYHA functional class were also those with the best quality of life at follow-up (DASI score 20.5 ± 8.6 vs 12.7 ± 7, p=0.028).
Conclusions: Patients who undergo isolated TV surgery continue to be a high-risk group in with high early and late mortality. There is no difference in mortality between TV repair and replacement at long-term follow-up. Our experience suggests that a shift towards earlier surgery may be proven to confer an advantage, as surgery before the onset of NYHA class 3 symptoms is associated with improved outcome and better quality of life.
