Abstract

Background: This study sought to determine the outcome effect of concomitant tricuspid valve operation for regurgitation during pericardiectomy for constrictive pericarditis. Methods: This cohort study included 310 patients with mild or greater tricuspid valve regurgitation who underwent pericardiectomy for constrictive pericarditis from 2000 to 2016 at the Mayo Clinic in Rochester, Minnesota. Patients were divided into 2 treatment groups: tricuspid valve operation (n = 68) and no tricuspid operation (n = 242). Survival analysis, proportional odds models, and landmark analysis were carried out to estimate the treatment effects of tricuspid valve operation. Results: Tricuspid valve regurgitation was graded mild in 203 (65%) patients, moderate in 69 (22%), and severe in 38 (12%). Tricuspid valve operation included repair in 54 patients (17%) and replacement in 14 (5%). Mechanical circulatory support was used more commonly in the intervention group (15% vs 5%; P = .009), but rates of stroke (3% vs 2%; P = .210) and mortality (9% vs 6%; P = .422) were similar. Tricuspid valve intervention resulted in a reduced risk of long-term mortality (hazard ratio, 0.68; 95% confidence interval [CI], 0.38 to 1.21; P = .192), less than moderate tricuspid valve regurgitation at follow-up (odds ratio vs moderate or severe, 0.093; 95% CI, 0.04 to 0.19), and less than moderate right ventricular enlargement at follow-up (odds ratio vs moderate or severe, 0.67; 95% CI, 0.35 to 1.24). Remnant severe right ventricular dysfunction resulted in increased risk of mortality (hazard ratio vs none or trivial, 4.87; 95% CI, 1.10 to 21.65; P = .037). Conclusions: Concomitant tricuspid valve operation for regurgitation can be performed without increased operative mortality during pericardiectomy for constrictive pericarditis. Operation appears protective against long-term mortality, residual tricuspid regurgitation, and right ventricular enlargement.
