ABSTRACT

Background. Adjustable segmental tricuspid annuloplasty is a new recently published procedure. The purpose of this prospective study was to present the technical advantages of this new tricuspid annuloplasty and Compare between it and De Vega repair and analyze its early and midterm results. Methods.between March 2015 and August 2016 in El-Hussain Hospital., 60 patients who had moderate or severe pure functional tricuspid regurgitation (TR), Patients were divided into 2 groups: (group A)30 patients where De Vega annuloplasty was performed and (group B)30 patients where segmental annuloplasty was performed, The decision for type of repair of tricuspid valve depended on randomization in the selection of two groups. The mean age of the patients was 34.87± 9.83 years and Females represented (46.7%) and (53.3%) of the patients in group A and B respectively. All patients had recent preoperative transthoracic echocardiography (TTE). two postoperative TTE were performed: (I) before the hospital discharge;(II) 6 months after surgery. Rsults: In Early postoperative ECHO: In group A 5 of patients (16.7%) had moderate TR, while in Group B no one have moderate TR. The difference between both groups is statistically significant. But in Late postoperative ECHO ( after 6 months)In Group A : 10 of patients (33.3%) have moderate TR, but 4 of them (13.3%) have moderate to severe TR, and finally 3 of them (10%) had severe degree of TR, while In group B : 3 of patients (10%) had moderate TR. The difference between both values is statistically highly significant. Conclusion: no hospital mortality was reported. Progressive overall clinical improvement was observed and postoperative TTE revealed that recurrence rate of TR occurs more in De Vega repair group, and result of repair was better in segmental repair group in early and midterm results.
