Sumario:BACKGROUND: Tricuspid annuloplasty (TAP) is accepted as the standard technique for correcting tricuspid regurgitation (TR). We conducted the present study to provide an overview of the contemporary results of 3D rigid ring annuloplasty for TR. METHODS: A systematic literature search was carried out in eight databases to collect all relevant studies on the three-dimensional (3D) rigid ring annuloplasty treatment of TR published before October 1, 2020. The main outcomes of interest were postoperative TR grade, perioperative mortality, and recurrent TR. RESULTS: A total of eight studies were included, all of which were retrospective observational studies. Rigid 3D rings were compared with flexible bands, and there was no difference in perioperative mortality [odds ratio (OR) = 1.02; 95% CI (0.52, 2.02); p = 0.95], late mortality [OR = 0.99; 95% CI (0.28, 3.50); p = 0.98], or recurrent TR [OR = 0.59; 95% CI (0.29, 1.21); p = 0.15]. The postoperative TR grade associated with 3D rigid rings was 0.12 lower [mean difference (MD) = −0.12; 95% CI (−0.22, −0.01); p = 0.03], which indicated that 3D rigid rings result in better postoperative outcomes than flexible bands. Compared with suture annuloplasty, the postoperative TR grade of the 3D rigid ring group was 0.51 lower [MD = −0.51; 95% CI (−0.59, −0.43); p < 0.05]. Within the 5 years of follow-up, patients who underwent 3D rigid ring annuloplasty had lower TR recurrence [OR = 0.26; 95% CI (0.13, 0.50); p < 0.05]. CONCLUSIONS: Compared with suture annuloplasty, 3D rigid rings present early advantages. The 3D rigid rings provide an acceptable short-term effect similar to that of the flexible bands, and a significant difference between these approaches was not discovered. However, the conclusion was based on the limited, short-term data available at the time of the study. Further research on the long-term effects of 3D rigid ring annuloplasty for TR is clearly needed.
