Supports equivalent PMBV outcomes in selected post-commissurotomy restenosis; extends observational data but leaves open need for randomized confirmation.
Does percutaneous mitral balloon valvuloplasty improve hemodynamics equally in patients with mitral restenosis after surgical commissurotomy compared to those with unoperated mitral stenosis?
Percutaneous mitral balloon valvuloplasty appears safe and equally effective in selected patients with mitral restenosis after previous surgical commissurotomy compared to those with unoperated mitral stenosis.
