Early outcome of tricuspid repair for functional tricuspid regurgitation associated with left-sided valve lesions: modified flexible band versus ring annuloplasty

Abstract

Background Repairing functional tricuspid regurge during left heart valve surgery in not uncommon. However, the technique of choice to achieve long-term results is still controversial. Although the DeVega technique was widely used, most surgeons have shifted to annuloplasty bands or rings to avoid early high failure rates and increased incidence of recurrent significant regurge. Objective To compare short-term results (1 year) of flexible band as a piece of tube graft (polytetraflouroethylene) annuloplasty versus ring annuloplasty for functional tricuspid regurge associated with left-side valve lesions. Patients and methods We prospectively studied 100 patients who underwent tricuspid repair during left-sided valve surgery at National Heart Institute. Thirty-one patients had ring annuloplasty whereas 69 patients had modified band annuloplasty. Echocardiography was done at discharge and after 1-year follow-up. Results There was no mortality in both groups. Mean age was 31 ± 10 years in group A and 30 ± 7 years in group B. Female sex was 67% in group A and 61% in group B. Five patients had mitral valve repair in group A versus four patients in group B, and the rest of the patient had their valve replaced. The mean cross-clamp time was longer in group B (117 ± 23) compared with group A (105 ± 19), with no significant difference between the two groups. There was no significant difference between the two groups regarding cardiopulmonary bypass time. Conclusion Tricuspid valve repair using modified band annuloplasty offers excellent results, which are comparable to ring annuloplasty over 1-year follow-up.
