Balloon valvotomy for mitral restenosis after open or closed surgical commissurotomy

Influence of the echocardiographic score and not of the previous surgical mitral commissurotomy on the outcome of percutaneous mitral balloon valvuloplasty

“…Although both authors reported smaller valvular areas after percutaneous mitral balloon valvuloplasty (1.6cm 2 ) than we did. Sharma et al 27 and Medina et al 28 found similar results in their 2 groups of patients for hemodynamic data and for mitral insufficiency, although the postsurgical mitral commissurotomy restenosis group of Sharma et al 27 had higher echocardiographic score.…”

“…The postsurgical mitral commissurotomy restenosis group was older, had higher echocardiographic scores, and had a tendency toward a higher percentage of atrial fibrillation and a larger mitral valve area before percutaneous mitral balloon valvuloplasty. Higher echocardiographic scores in this group of patients have been found also by others 27 .…”

Resultados da valvoplastia por balão do grupo submetido a plastia mitral percutânea ou cirúrgica prévias com o tratado pela primeira vez: evolução do grupo com plastia prévia

“…There were no differences in the functional class ratings before the procedure, mitral valve area before or after the procedure and mitral valve failure after the procedure. The echocardiograph score was higher for the patients that had previously undergone interventions which agrees with other studies 51 .…”

“…Nevertheless, both authors obtained valve areas much lower (1.6 cm 2 ) than those obtained in our present and previous studies 29,49 . Sharma et al 51 and Medina et al 52 found similar results in their two patient groups, for both the hemodynamic data and mitral failure…”

“…rates even though the post commissurotomy mitral group of Sharma et al 51 had a higher echocardiograph score.…”
