Purpose : Tricuspid annuloplasty (TAP) is one of the most frequently performed concomitant procedure in valve surgery. We aimed to analyze the risk factors of recurring tricuspid regurgitation (TR) after TAP.
Methods : A total of 234 patients who underwent TAP during 2003 to 2019 were included. Ninety-two patients (39%) were men, and mean age was 63±12 years. Preoperative TR severity was as follows; none (n=15, 6%), mild (n=1, 0.4%), mild-to-moderate (n=26, 11%), moderate (n=92, 39%), moderate-to-severe (n=8, 3%), and severe (n=92, 39%). Number of valves operated was as follows; single valve (n=14, 6%), double valve (n=174, 74%), and triple valve (n=46, 20%). TR recurrence was defined as newly detected TR (≥ moderate) during follow-up.
Results : Median follow-up time was 67±6 months. Ten-year overall survival was 82±3% and 10-year freedom from major adverse cardiovascular or cerebrovascular event was 77±3%. Among all patients, 26 patients (11%) had recurred TR and 50 patients (21%) died without TR recurrence, while the remaining 158 patients (68%) survived without recurred TR by the closure of follow-up. Competing risk analysis identified patient age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.03-1.11, P=0.001) and chronic obstructive pulmonary disease (COPD) (OR 2.04, 95% CI 1.08-3.86, P=0.028) as independent predictors of TR recurrence. Preoperative TR grade, presence of atrial fibrillation, Maze operation, and ring size were not independent predictors of TR recurrence during follow-up.
Conclusion : Older age and COPD were risk factors of TR recurrence after TAP. When performing TAP in this subgroup, care should be taken to prevent TR recurrence.
