title: The advantages of open mitral commissurotomy for mitral stenosis.
abstract: Mitral commissurotomy is the treatment of choice for mitral stenosis. If this is not feasible, replacement of the valve becomes necessary. Open commissurotomy has been performed at Loyola University Medical Center, Maywood, Ill, in 105 patients since 1970. The mean age was 45 years. The indication for surgery was heart failure in 92 of the cases. Sixty of the patients were in class 3 of the New York Heart Association (NYHA) classification. Eighty-five underwent open mitral commissurotomy alone. This was not feasible in 42 patients scheduled for it who required valvular replacement. Twenty-five patients had a left atrial thrombus. Two patients died, one from aortic dissection and the other from acute infarction in the perioperative period. Ninety-eight patients are NYHA class 1 or 2 at present. Two patients required valvular replacement following the commissurotomy. The low mobidity and mortality with excellent long-term results support our contention that open mitral commissurotomy is the treatment of choice for mitral stenosis.
