BACKGROUND: Mitral valve (MV) disease is often accompanied by concomitant tricuspid valve (TV) disease. This study determined the influence of performing TV procedures in the setting of MV operations within a multiinstitutional patient population.
METHODS: From 2001 to 2008, 5,495 MV operations were performed at 17 different statewide centers. Of these, 5,062 patients (age, 63.4 ± 13.0 years) underwent an MV operation and 433 (age, 64.0 ± 14.2 years) underwent combined MV and TV (MV+TV) operations. The influence of concomitant TV procedures on operative death and the composite incidence of major complications was assessed by univariate and multivariate analyses.
RESULTS: Patients undergoing MV+TV were more commonly women (62.7% vs 45.5%, p < 0.001), had higher rates of heart failure (73.7% vs 50.9%, p < 0.001), and more frequently underwent reoperations (17.1% vs 7.4%, p < 0.001) compared with MV patients. Other patient characteristics, including preoperative endocarditis (8.5% vs 8.2%, p = 0.78), were similar between groups. MV replacement (63.5%) was more common than repair (36.5%, p < 0.001) in MV+TV operations, and MV+TV operations incurred longer median cardiopulmonary bypass times (181 vs 149 minutes, p < 0.001). Unadjusted operative mortality (6.0% vs 10.4%, p = 0.001) and postoperative complications were higher after MV+TV compared with MV. More important, risk adjustment showed performance of concomitant TV procedures was an independent predictor of operative death (odds ratio, 1.50; p = 0.03) and major complications (odds ratio, 1.39; p = 0.004).
CONCLUSIONS: A concomitant TV operation is a proxy for more advanced valve disease. Compared with MV operations alone, simultaneous MV+TV operations are associated with elevated morbidity and death, even after risk adjustment. This elevated risk should be considered during preoperative patient risk stratification.
