Influência do escore ecográfico e näo da comissurotomia cirúrgica prévia no resultado da valvoplastia mitral percutânea por baläo / Influence of the echocardiographic score and not of the previous surgical mitral commissurotomy on the outcome of percutaneous mitral balloon valvuloplasty

OBJECTIVE: To evaluate prior mitral surgical commissurotomy and echocardiographic score influence on the outcomes and complications of percutaneous mitral balloon valvuloplasty. METHODS: We performed 459 complete mitral valvuloplasty procedures. Four hundred thirteen were primary valvuloplasty and 46 were in patients who had undergone prior surgical commissurotomy. The prior commissurotomy group was older, had higher echo scores, and a tendency toward a higher percentage of atrial fibrillation. RESULTS: When the groups were compared with each other, no differences were found in pre- and postprocedure mean pulmonary artery pressure, mean mitral gradient, mitral valve area, and mitral regurgitation . Because we found no significant differences, we subdivided the entire group based on echo scores, those with echo scores <=8 and those with echo scores >8 the mitral valve area being higher in the <=8 echo score group 2.06Ý0.42 versus 1.90Ý0.40cm² (p=0.0090) in the >8 echo score group. CONCLUSION: Dividing the groups based on echo score revealed that the higher echo score group had smaller mitral valve areas postvalvuloplasty

Baläo único versus baläo de inoue na valvoplastia mitral percutânea por baläo: resultados imediatos e complicaçöes / Single balloon versus inoue balloon in percutaneous mitral balloon valvuloplasty: short-term results and complications

Objetivo - Avaliar os resultados imediatos e complicaçöes da valvoplastia mitral percutânea por baläo (VMPB), com o baläo de Inoue (BI) e com o baläo único (BU). Métodos - Dentre 390 procedimentos utilizaram-se o BI em 29 procedimentos e o BU de baixo perfil em 337. Näo houve diferença na idade e sexo nos 2 grupos. O grupo BI era menossintomático (p=0,0015). Não houve diferença na distribuição do escore ecocardiográfico e da área valvar mitral (AVM) pré-VMPB. Resultados - Quando compararam-se os 2 grupos entre si, os resultados nos grupos BI e BU foram, respectivamente: pré-VMPB para pressäo pulmonar média (PPM) ..."fórmula"...Só houve complicaçöes no grupo BU. Conclusäo - As duas técnicas foram eficientes. Os resultados hemodinâmicos foram semelhantes, embora a AVM pós-VMPB do grupo do BI foi maior.
