Supports consideration of balloon mitral valvuloplasty in post-commissurotomy restenosis; leaves open need for randomized confirmation of durability.
Does percutaneous balloon mitral valvuloplasty improve echocardiographic outcomes in patients with mitral restenosis after previous surgical commissurotomy compared to patients with unoperated mitral stenosis?
Balloon mitral valvuloplasty is safe and effective for patients with mitral restenosis after previous surgical commissurotomy, yielding similar immediate and midterm results as in patients with de novo mitral stenosis.
