Background: Management of moderate functional tricuspid regurgitation (FTR) secondary to left-sided valve lesion is controversial. The objective of this study was to compare the short-term results of surgical repair versus conservative treatment for moderate functional tricuspid regurgitation in concomitant with mitral valve surgery.
Methods: Our study included 60 patients with mitral valve lesion and moderate functional tricuspid regurgitation. Patients were divided into 2 groups; group A included 30 patients whose tricuspid valve disease were managed conservatively, and group B included 30 patients who had tricuspid valve band annuloplasty.
Results: Preoperative clinical and echocardiographic data were comparable between groups. There was no difference regarding mechanical ventilation time (6 .13 ± 3.02 vs. 7.01 ± 4.14 hours; p= 0.291), or intensive care unit stay (51.42 ± 12.1 vs. 52.31 ± 15.32 hours; p=0.614) in group A and B respectively. There was a significant improvement in the degree of tricuspid valve regurgitation in group B early postoperative (moderate tricuspid regurgitation reported in 22 (73.3%) vs. 4 (13.3%); p<0.001) and at 3 months (moderate tricuspid regurgitation 11 (36.7%) vs. 2 (6.7%); p<0.001) and 6 months follow up (moderate tricuspid regurgitation 10 (30%) vs. 2 (6.7%); p<0.001) in group A and B respectively. After 6-months, 20 (66.7%) patients in group A had dyspnea grade I compared to 26 (86.7%) patients in group B; p=0.021.
Conclusion: Although the correction of the left-sided lesion improved the degree of TR in some patients, concomitant repair of the tricuspid valve could produce better improvement in the clinical outcome when compared to the conservative approach.
