The authors elaborated the problem of abnormal hypertrophy of the musculature of the right ventricular cavity. From a total number of 534 children subjected to complete cardiological examination in 28 (5.2%) they made the diagnosis of an inborn anomaly of the musculature of the right ventricle localized beneath the infundibulum. The classification of this pathological entity is based on angiocardiographic and catheterization findings. The patients were divided into three groups: group I comprised 6 patients with an associated defect of the ventricular septum. Obstruction caused by hypertrophy of the muscle bundles created a morphological and functional right ventricle with two cavities. Group II comprised 15 patients where the authors confirmed by catheterization and angiocardiography an obstruction at the site of the hypertrophic musculature. Group III comprised 7 patients where they proved hypertrophy of the musculature by angiocardiographic examination but were unable to confirm the obstruction by catheterization.
