[Treatment of stenosis of the aortic orifice by the method of balloon dilatation].
Methods for balloon dilatation of stenosis of the aortic orifice through an arterial and venous approaches are suggested. The method was approved in treatment of 51 patients whose ages ranged from 4 to 63 years. Retrograde advancement of the balloon to the constricted part is most rational. In antegrade movement of the balloon there is a hazard of inflicting injury to the structures of the mitral valve (4 cases). Both methods produce a similar therapeutic effect: the area of the orifice increased 4.3 times, the systolic pressure gradient reduced by 3.3 times. II degree aortic insufficiency developed in 2 patients and I degree insufficiency in 3 patients. The method may be an alternative in the treatment of valvar and membranous subvalvular aortic stenosis.
