Dacron Band versus de Vega Annuloplasty for Functional Tricuspid Regurgitation

Abstract

Background: Typically Functional (secondary) tricuspid insufficiency is the most prevalent tricuspid valve disease on top of mitral diseases. Different repair techniques were introduced to deal with this problem. Objectives: The target of this study was to evaluate the repair of Tricuspid valves using a commonly used suture annuloplasty technique (DE VEGA) versus a patient-tailored synthetic band made of Dacron short-term results. Patients and methods: From January 2021 to October 2022, 40 patients with secondary tricuspid insufficiency participated in our prospective cohort single-center study. we equally split the patients into two different groups. A total of 20 patients were randomized to the flexible Dacron band group while the remaining 20 patients were allocated to the De-Vega annuloplasty technique group. Preoperative data, major intraoperative and immediate postoperative adverse events, and postoperative regurgitation were assessed. Results: studied groups’ properties regarding Demographic and Preoperative echo data were statistically comparable. The rate of acute postoperative morbidities and complications had no statistical significance. There was no significant difference in postoperative recurrence of tricuspid insufficiency Around (85%) of patients in the De-Vega group and (90 %) in the Band group did not have TR on discharge and after 6 months of follow-up. There was no statistical significance in the incidence of immediate post-operative complications. Conclusions: Tricuspid repair using a customized Dacron band is a reliable surgical technique for functional Tricuspid Regurgitation. Additional studies with a larger number of patients and a longer term of follow-up are needed to confirm our findings.
