title: [Clinical course, diagnosis and surgical treatment of congenital aortic stenosis].
abstract: In 39 patients aged from 2 1/2 to 35 years the results of surgical treatment of congenital aortic stenosis are analyzed. Electro-, phonocardiographic and roentgenological findings along with those obtained through catheterization of the left cardiac chambers prior to surgery are described in detail. All these patients were divided into 3 groups, depending upon extent of deranged hemodynamics. The 1st group included 10 persons with a moderate aortic stenosis. The systolic gradient between the left ventricle and the aorta did not exceed in them 30 mm Hg. The 2nd group counted 20 patients with a well-marked aortic stenosis and a systolic pressure gradient between 30 and 80 mm HG. The 3d group embraced 9 patients with an acute aortic stenosis. Here the systolic gradient was in excess of 80 mm Hg. Surgery was performed in 35 patients under a moderate hypothermia and with extracorporeal circulation. Thirteen (33.3 per cent) patients died during surgery and in the post-operative period.
