[Hypertrophic cardiomyopathy in children (author's transl)]

Based on their experience of 6 cases of idiopathic hypertrophic cardiomyopathy among 1800 hemodynamic studies, the authors discuss some features of this entity, and print out the phonomecanocardiographic datz leading to the suspicion of the diagnosis, and the angiocardiographic findings which confirm it. Some speculation is made on the probable congenital and hereditary etiology of the disease, and finally, the main therapeutic measure are considered.
