- Abstract
Objectives: To evaluate the impact of concomitant tricuspid valve (TV) repair on the right ventricular (RV) function postoperatively and within the 6 months following degenerative mitral valve (MV) repair. Methods: The prospective study included 37 patients (mean age 57.32 ± 2.13 years) with severe MV regurgitation due to primary MV prolapse. Nineteen underwent successful MV repair (TV(−) group). Additional TV repair due to moderate-to-severe TV regurgitation was performed in 18 (TV(+) group). Two-dimensional (2D) speckle-tracking and tissue Doppler echocardiography was performed for all patients before surgery and 7 days and 6 months after surgery. Results: Preoperative dimensions and indices of RV longitudinal function did not differ between the groups (right ventricle end-diastolic diameter (RVEDD) was 33.53 ± 0.94 mm vs. 34.67 ± 1.72 mm, tricuspid annular systolic motion (S') was 15.06 ± 0.85 cm/s vs. 16.0 ± 1.27 cm/s, tricuspid annular plane systolic excursion (TAPSE) was 24.02 ± 1.06 mm vs. 22.4 ± 1.36 mm, respectively; p>0.05). RVEDD decreased significantly and did not change within the follow-up in the TV(−) group. In the TV(+) group, RVEDD decreased early after surgery and more markedly six months later in comparison to the TV(−) group. Indices of RV systolic longitudinal function decreased early after surgery and had a tendency to increase after six months in both groups. Regional longitudinal strains of the lateral RV wall decreased early after surgery and improved within the six months in the TV(−) group and did not change significantly in the TV(+) group. Conclusions: Additional TV repair in degenerative MV repair more markedly reduces RV dimensions and does not have a negative impact on RV systolic function in comparison to an isolated MV repair although these conclusions are of limited value due to the lack of a control group.
