Abstract
Objective: Functional tricuspid regurgitation (FTR) is the most common type of tricuspid insufficiency and occurs approximately in 30% of patients with mitral valve disease. The major etiologic factor in the triggering of right ventricular dilation and thus causing functional tricuspid regurgitation, is pulmonary artery hypertension secondary to mitral valve disease. We aimed to analyze long-term outcomes of patients with mild tricuspid regurgitation at the time of mitral valve replacement. Methods: Sixty-six patients with mild tricuspid insufficiency who underwent mitral valve replacement were included in this observational ret- rospective study. Mean follow-up time was 8.3±0.7 years. Patients whose tricuspid regurgitation remained unchanged or decreased following operation were enrolled to group 1 (n=32), patients whose tricuspid regurgitation increased were included to group 2 (n=34) and data were compared statistically with t-test, Mann-Whitney U, Chi-square and Fisher Exact test. Multiple regression analysis was performed to determine independent risk factors for FTR progression. Results: Preoperatively female gender (p=0.02), body surface area (p=0.04), left atrium diameter (p=0.01), functional capacity (p=0.03), right ventricle diameter (p=0.04), and left ventricle mass index (p=0.04) were found to be statistically significant between groups. In the follow-up; functional capacity, grade of tricuspid insufficiency, pulmonary artery pressure, vena contracta width (p
