Percutaneous balloon mitral valvotomy in mitral restenosis

Abstract

We conclude that percutaneous balloon mitral valvotomy can be performed safely and effectively in patients with mitral restenosis following surgical valvotomy; the beneficial acute outcome is sustained, as shown at intermediate-term follow-up and is similar to that of patients undergoing balloon mitral valvotomy as an initial procedure.

Percutaneous balloon mitral valvuloplasty in severe restenosis of the mitral valve: Analysis of factors affecting the short term outcomes – A single center experience

“…In our study, patients who had successful PBMV had lower Wilkin's score, and bilaterally fused commissural morphology (6,12), consistent with the findings of Turgeman, et al and Hung, et al who demonstrated that a more abnormal echocardiographic morphology predicted less symptomatic improvement and had a smaller post procedure valve area (9,13).…”

“…Previous MV intervention was not associated with sub optimal outcomes, similar to the findings of Guptha et al who analysed 614 consecutive patients undergoing REDO PTMC including 8 patients (13.2%) with second mitral restenosis following prior surgical valvotomy (13). They found that percutaneous balloon mitral valvotomy can be performed safely and effectively in patients with mitral restenosis following surgical valvotomy.…”

“…This finding is similar to observer of Abascal et al who also found a correlation between development of MR and higher Wilkins score . Fatkin et al demonstrated the influence of commissural calcification on the short-term outcome in a series of 30 patients undergoing first PBMV (13). Subsequently, Cannan et al studied 149 patients and found that presence of commissural calcification as identified by 2D echocardiography was a useful predictor of outcome after first PTMC.…”

Comparação da evolução a longo prazo da valvoplastia mitral percutânea por balão com a técnica de inoue versus a do balão único: análise dos fatores de risco para óbito e eventos maiores

“…In accordance with literature, there were more females in both study groups 3,12,18,20,22 and a greater percentage in the single balloon group in the present study.…”

“…The occurrence of severe mitral regurgitation during the procedure predicted events during long term evolution in other studies 11,12,13,19,22,32,35 and mitral regurgitation can be predicted by a specific echocardiographic score 36 . Mitral regurgitation before the valvuloplasty is a predictor of reduced event free survival 11 .…”
