Outcomes of Mild to Moderate Functional Tricuspid Regurgitation in Patients Undergoing Mitral Valve Operations: A Meta-Analysis of 2,488 Patients.

This meta-analysis examined the prognosis of patients who were found to have mild to moderate functional tricuspid regurgitation during mitral valve operations. Overall, this meta-analysis included 2,488 patients in 10 studies. Compared with the group without tricuspid valve annuloplasty, the probability of not progressing to moderate to severe functional tricuspid regurgitation was significantly higher in the tricuspid valve annuloplasty group. A more aggressive surgical approach involving concomitant tricuspid repair with mitral valve operations may be considered to avoid the development of moderate to severe functional tricuspid regurgitation in the follow-up.
