May warrant closer surveillance after balloon mitral valvuloplasty in prior valvotomy patients; leaves open optimal selection criteria for prospective trials.
Cohort (n=19)
A smaller post-procedural mitral valve area (<1.6 cm2) and higher echo-score independently predict restenosis after balloon mitral valvuloplasty in patients with prior surgical valvotomy.
Ha et al. (1996) conducted a cohort in mitral restenosis after surgical valvotomy (n=19). Percutaneous Balloon Mitral Valvuloplasty was evaluated on Restenosis. Restenosis occurred in 42% of patients after balloon mitral valvuloplasty for surgical valvotomy restenosis; independent predictors were post-procedure valve area (p=0.0013) and echo-score (p=0.0244).
