Abstract

Background

The influence of the etiology of mitral valve (MV) lesion on outcomes of concomitant repair for functional tricuspid regurgitation (TR) is not well studied. Our objectives were to compare long-term survival and TR recurrence after tricuspid valve (TV) repair concomitant with surgery for rheumatic versus degenerative MV disease.

Methods

We included 480 patients who had concomitant MV and TV surgery from 2009 to 2019. We grouped the patients into Group 1 (n = 345; rheumatic MV) and Group 2 (n = 135; degenerative MV). Propensity score matching identified 104 matched pairs.

Results

There was no significant difference in survival between groups before (p = .46) or after matching (p = .09). There was no difference in the recurrence of moderate TR (subdistributional hazard ratio [SHR]: 1.22 [0.77−1.95], p = .40). Recurrent TR was significantly associated with the preoperative TR grade (SHR: 1.8 [1.5−2.16], p < .001); body mass index (SHR: 1.05 [1.03−1.08], p < .001), and the use of flexible versus rigid TV prosthesis (SHR: 0.64 [0.41−0.99], p = .042). Recurrence of TR was higher with MV replacement compared with repair (SHR: 1.69 [1.03−2.78], p = .038). The change in the degree of TR did not differ between groups before matching (OR: 0.77 [0.56−1.04], p = .09) or after matching (OR: 0.98 [0.67−1.44]; p = .93).

Conclusion

Outcomes of concomitant TR repair were comparable in rheumatic and degenerative mitral pathology. Type of the TV prosthesis and TR grade affected TR recurrence. MV repair could be associated with a lower recurrence of TR compared with replacement.
