Open mitral commissurotomies. Analysis of 100 cases.
Routine use of open mitral commissurotomy in all cases of rheumatic mistral stenosis is the recommended treatment of choice in recent years. Effective division of the subvalvular apparatus (chordae tendineae and papillary muscles) can be accomplished easily during open commissurotomy and therefore recurrences after the open approach is less than the recurrences after closed commissurotomy. These subvalvular elements can not be freed easily during closed mitral commissurotomy. Low mortality rates after open approach suggests that this operation can be performed safely in cases of MS. Open approach has several advantages versus closed commissurotomy. We believe that closed commissurotomy should be replaced by open commissurotomy in all cases of MS.
