title: [Demonstration of obstruction of blood outflow from the left and right ventricles in idiopathic hypertrophic subaortic stenosis].
abstract: A comparative assessment of the value of routine clinical and intracardiac investigation procedures for the diagnosis of idiopathic hypertrophic subaortic stenosis (IHSS) was carried out in 12 patients with simultaneous obstructions of the left- and right-ventricular blood outflow pathways caused by hypertrophy of the interventricular septum. It is suggested that electrocardiographic and roentgenologic evidence of overloaded right and left compartments of the heart signals are indicative of the need for simultaneous catheterization and angiocardiography of the right and left compartments that can detect right-ventricular obstruction in the IHSS patients. Intravital diagnosis of the obstruction makes possible complete correction of the defect, whereas an isolated removal of the left-ventricular obstruction is not successful in the presence of an obstruction in the right ventricle.
