Outcome of suture annuloplasty (De Vega) versus ring annuloplasty for functional tricuspid valve regurgitation concomintant with mitral valve surgery

Abstrakt

Background: The optimal surgical technique for functional tricuspid regurgitation (TR) repair is still a topic for ongoing research. The DeVega technique is still used frequently in developing countries. Thus, this study aimed to compare the outcomes of tricuspid valve repair using DeVega vs. ring annuloplasty for managing severe functional TR during mitral valve surgery. Methods: This retrospective chart review included 66 patients. The study included patients with simultaneous tricuspid valve repair during mitral valve intervention. The patients were recruited from 2018 to 2022. The study had two groups: the first group included 50 patients who underwent the DeVega technique (Group A), and the second group included 16 patients who underwent tricuspid repair with a ring (Group B). Results: The mean age did not differ significantly, and it was 36.1±4.6 years in Group A vs. 38.4±2.4 years in Group B (P= 0.06). Females accounted for 64% of patients with DeVega vs. 56% of patients with ring annuloplasty (P=0.578). Mitral valve replacement was performed in 39 patients (78%) in Group A and 12 patients (75%) in Group B (P>0.99). Ischemic time was comparable between the groups (60.3± 3.78 vs. 59.06± 2.91 min; P= 0.234). The cardiopulmonary bypass time was significantly longer with ring annuloplasty (92.54± 22.57 vs. 109.56± 28.58 min; P= 0.017). There was no difference in postoperative inotropic use between the groups (16 (32%) vs. 4 (25%); P= 0.596). The duration of mechanical ventilation (6.78± 1.76 vs. 5.96± 1.85 hours; P= 0.114), ICU stay (2.08± 0.4 vs. 2.06± 0.57; P= 0.876), and hospital stay (7.96± 1.07 vs. 8.25± 0.86; P= 0.328) were not significantly different between groups. The postoperative degree of TR (P= 0.163) and after one year (P= 0.119) were comparable between groups. Conclusions: DeVega annuloplasty could effectively manage severe TR concomitant with mitral valve surgery. The results of DeVega repair were comparable to those of ring annuloplasty after one year.
