Comparative study of tricuspid valve repair using ring vs. synthetic band in severe functional tricuspid valve regurgitation

Background: Functional tricuspid valve regurgitation secondary to left-sided valve disease remains a common problem. There are different surgical techniques for tricuspid valve repair; however, the superiority of one approach over the other has not been proven. Our objective was to compare the short-term results of ring versus synthetic band annuloplasty to repair functional severe tricuspid regurgitation in patients with left-sided valve lesions. Methods: This retrospective study includes 60 patients who underwent left-sided valve replacement with concomitant tricuspid valve repair for severe tricuspid regurgitation. Patients were divided into group A (n= 30), patients with rigid rings, and group B (n= 30), patients with synthetic bands. Results: The preoperative demographic and clinical data were non-significant between both groups. In the preoperative data, the tricuspid annular plane systolic excursion (TAPSE) was significantly higher in the ring group (2.84 ± 0.53 vs. 2.3 ± 0.4, P< 0.001). Hospital stay was more prolonged in group B (10.05 ± 1.57 vs. 11.7 ± 2.76 days, P=0.006). There were no differences in other operative and postoperative data between groups. After a six-month follow-up, both groups had no significant difference regarding the clinical data or the degree of tricuspid valve regurgitation. Conclusion: Tricuspid valve annuloplasty with a rigid ring or synthetic band for tricuspid regurgitation could have a good short-term outcome
