title: Idiopathic hypertrophic subaortic stenosis. V. Analysis of the shape of the left ventricular cavity at the end of diastole.
abstract: The angiographic appearance of the end diastolic left ventricular cavity in 4 patients with obstructive idiopathic hypertrophic subaortic stenosis is characterized by a model in projective geometry. The muscular interventricular septum, catenoid-like (convex longitudinally and concave transversely towards the left ventricular cavity), has an oblique long axis of the catenoid relative to the apicomidaortic axis of the left ventricle. The cavity is shallow in its mid- and apical parts.
