Background: Performance of tricuspid annuloplasty (TA) in patients undergoing mitral valve surgery is recommended based on the degree of tricuspid regurgitation and tricuspid annulus size, but is often underused.
Aim: To evaluate the impact of combined TA on in-hospital outcome in patients undergoing mitral valve replacement (MVR).
Methods: We selected all consecutive patients who underwent MVR for native valve disease. Clinical, echocardiographic and in-hospital complications were obtained from chart review.
Results: We identified 287 patients (mean age 62±17 years; 44% men). Combined TA was performed in 165 patients (57%), who had more rheumatic disease (71% vs. 24%; P<0.0001) and mitral stenosis (55% vs. 22%; P<0.0001), but less endocarditis (4% vs. 31%; P<0.0001), were more often in atrial fibrillation (54% vs. 22%; P<0.0001), were more severely symptomatic (80% vs. 57%; P<0.0001), presented with a higher systolic pulmonary artery pressure (SPAP) (53±16 vs. 45±15mmHg; P=0.0002) and were less likely to have required emergency surgery (17% vs. 38%; P<0.0001). Despite this higher risk profile, in-hospital mortality was slightly lower (5% vs. 13%; P=0.02) and complication rates were similar (redo surgery 22% vs. 16% [P=0.18] and tamponade 20% vs. 15% [P=0.15]). After adjustment for age, sex, functional class, SPAP, emergency surgery and concomitant coronary artery bypass graft or aortic valve replacement surgery, combined TA was not associated with an increased rate of in-hospital death (P=0.08) or major complications (P=0.89).
Conclusions: In a consecutive series of patients who underwent MVR, TA did not seem to have a negative impact on immediate outcome. Hence, additional performance of TA at the time of MVR should not be declined on the basis of an increased surgical risk.
