Short-Term Outcome of Tricuspid Valve Annuloplasty Using the Modified De Vega Technique

Abstract

Objectives: The aim of this study is to evaluate short-term results and efficacy of tricuspid valve annuloplasty by the modified De Vega technique. Study design: A prospective cohort study. Setting:Cardiothoracic Surgery Department in collaboration with general surgery department, Qena University Hospital, South Valley University, Qena, Egypt. Duration: FromOctober 2018 to January 2020. Subjects and Methods:25 patients underwent tricuspid valve annuloplasty for functional TR caused by Rt sided dilatation secondary to the left-sided valvular lesion. Informed consent was obtained from all patients in this study. Pts with mild TR, (organic) tricuspid regurgitation or TV endocarditis, and isolated TV lesions were excluded from the study. Result(s):Follow-up echocardiography after 6 months did not show any severe tricuspid regurgitation, but otherwise, most of the patients with mild tricuspid regurge 17 pts (68%) and 8 patients (32%) with moderate regurge, as regard ejection fraction and LV dimensions there were no difference, while there was a significant reduction in LA diameter, pulmonary artery pressure, and RV diameter with p value <0.05. Conclusion(s): Tricuspid valve annuloplasty with a modified De Vega technique in functional TR was associated with a lesser residual degree of TR and could be considered a reliable procedure in TV repair in short term follow-up. Recommendations: Larger sample size and longer follow-up duration should be done
