Does functional tricuspid regurgitation progress over time after successful mitral valve repair for functional ischemic mitral regurgitation?
Absolute Event Rate: 44% vs 67%
Close to 50% of patients develop significant tricuspid regurgitation after successful mitral valve repair for functional ischemic MR, with the incidence increasing over time and predicted by preoperative tricuspid annulus dilation.
Matsunaga et al. (2005) conducted a cohort in Functional ischemic mitral regurgitation (n=70). Tricuspid valve repair vs. Surgically ignored tricuspid valve was evaluated on Residual tricuspid regurgitation. After mitral valve repair for functional ischemic mitral regurgitation, 49% of patients had significant tricuspid regurgitation at follow-up, with incidence increasing to 74% at >3 years.
