[Reutilization of the right-side approach in commissurotomy in recurrent mitral stenosis].

Based on histotopographic studies of heart specimens taken from patients died after commissurotomy with a right-side approach, and the experience with eleven mitral commissurotomies using an access via the interatrial septum repeatedly, it is concluded that a close mitral commissurotomy for reccurrent mitral stenosis with the repeat use of a right-side approach seems to be anatomically grounded and easy to be performed from the point of view of the operative technic. This intervention should be accomplished in patients with recurrent mitral stenosis, previously operated upon with a right-side access. The opportunities of reused right-side approach offer prerequisites for its wider application in primary commissurotomy.
