Avaliação comparativa entre valvoplastia percutânea e comissurotomia a céu aberto na estenose mitral

Abstract

Both procedures were safe and showed similar immediate improvement in mitral gradient and functional class. Mitral valve area had a greater increase immediately after commissurotomy, however, there was a significantly greater reduction in the CG after 12 months of follow-up, when compared to balloon valvuloplasty. In both groups, mitral gradient remained reduced and most patients did not change functional class during the follow-up.

Evolução tardia da comissurotomia mitral em pacientes reumáticos com baixo escore ecocardiográfico

“…In our country, Cardoso et al [7] in a prospective, randomized study compared the results of open mitral commissurotomy with the balloon valvuloplasty in 88 patients with rheumatic mitral stenosis, with scores <9. The group submitted to balloon valvuloplasty had an increase in the average mitral valve area of 1.05 ± 0.25 cm² to 2.18 ± 0.40 cm², while the commissurotomy group had an increase of 0.98 ± 0, 21 ± 0.46 cm2 to 2.52 cm².…”

“…In our midst, Cardoso et al [7] presented a study comparing open commissurotomy with balloon valvuloplasty, with advantage over the increase in valve area for the group submitted to commissurotomy.…”

Valvoplastia mitral percutânea por balão: evolução a longo prazo e análise dos fatores de risco para óbito e eventos maiores

“…Palacios et al 24 also found higher mortality in the group with higher echocardiographic score. Thus, reported mortality during outcome is null in groups selected with favorable medium term 64,65 , and even long term 17 characteristics. Mortality reached 17 and 18% 21,36 , due to the unfavorable characteristics or when greater follow-up period were observed.…”
