TRICUSPID VALVE REPAIR – OUR EARLY EXPERIENCE WITH EDWARDS C-E PHYSIO TRICUSPID ANNULOPLASTY RINGS

Abstract

Objectives: Very few studies can be found in the current literature regarding post-operative outcome of contoured tricuspid annuloplasty rings. The aim of our study was to analyse our early results of tricuspid annuloplasty using contoured annuloplasty rings and to compare Medtronic Contour 3D ring with Edwards C-E Physio Tricuspid ring.

Material and Methods: A retrospective analysis of our hospital records was done to analyze the outcome of patients who had undergone tricuspid valve repair using contoured annuloplasty rings between June 2021 and January 2022. Post-operative transthoracic echocardiography was done to assess any residual tricuspid regurgitation and patients were clinically assessed using NYHA functional classification. Average duration of follow-up for all patients was 5.6 ± 2 months (3-10).

Results: We identified 50 patients for the study among which 25 patients had Contour 3D ring implant and 25 patients had Physio Tricuspid ring implant. Average age of the patients was 32.6 ± 12 years. There was significant improvement in NYHA functional class, grade of tricuspid regurgitation and PASP in both groups. However, comparison between Physio Tricuspid ring and Contour 3D ring did not reach any clinical significance.

Conclusion: Edwards C-E Physio Tricuspid annuloplasty ring has shown promising early results in our study with low rates of recurrent tricuspid regurgitation and significant clinical improvement. The results are comparable with Medtronic Contour 3D ring with no significant difference between the two types of rings. However, the sample size being small and follow-up being short, larger and long-term studies shall follow to confirm the findings of the present study
