Background and aim of the study: Although significant late tricuspid regurgitation (TR) may develop after surgery for degenerative mitral regurgitation (MR), the use of routine tricuspid annuloplasty is debatable. The study aim was to determine the prevalence and predictors of significant late TR after surgery for degenerative MR.

Methods: A total of 112 patients who had undergone surgery for degenerative MR without concomitant tricuspid valve repair (average follow up 7.7 ± 4.0 years) was studied retrospectively. The prevalence of post-surgical TR and predictors of progression were determined.

Results: The majority of patients (97%) had non-significant TR (less than moderate) prior to surgery, although an overall trend of progression towards significant TR (grades

2 or 3) was noted in 17 patients (p = 0.0006). Of the 18 patients (16%) with late postoperative significant TR, only nine (8%) had severe TR with only a single referral to surgery. New-onset post-surgical atrial fibrillation was more common in patients who developed late significant TR (p = 0.002). Multivariate analysis of the pre-surgery variables, age >65 years and left ventricular dysfunction were shown to be independent predictors of late functional TR.

Conclusion: Significant progression in TR after surgery for degenerative MR was rare in this patient cohort. The impact of older age and left ventricular dysfunction at the time of surgery showed a strong association with post-surgical atrial fibrillation.
