Key result
Mitral valve repair for mitral restenosis after percutaneous balloon mitral valvotomy significantly increased mean mitral valve area from 1.16 cm2 to 1.62 cm2, with a 5-year event-free survival of 56.16%.

May improve hemodynamics in selected cases; leaves open whether repair outperforms replacement for post-valvotomy restenosis.

Does mitral valve repair improve outcomes in patients with symptomatic mitral valve restenosis after percutaneous balloon mitral valvotomy?
Absolute Event Rate: 1.62% vs 1.16%
p-value: p=0.0001
Mitral valve repair for restenosis after percutaneous balloon mitral valvotomy improves valve hemodynamics but has a modest 5-year event-free survival of 56.16%, suggesting it may not be a definitive alternative to replacement for all patients.
Lee et al. (2015) conducted an observational in Symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy (n=15). Mitral valve repair vs. Preoperative baseline was evaluated on Mean mitral valve area (cm2) (p=0.0001). Mitral valve repair for mitral restenosis after percutaneous balloon mitral valvotomy significantly increased mean mitral valve area from 1.16 cm2 to 1.62 cm2, with a 5-year event-free survival of 56.16%.
