[Disorders of the cardiovascular system in congenital lentiginosis].

The authors investigated during the last 10 years four patients with lentiginosis and affection of the heart. In none of them the symptoms were complete enough to include it under the leopard syndrome. In two patients the authors found changes in the outflow portion of the right ventricle which was in their opinion caused by hypertrophy of the interventricular septum and musculature of the right ventricle. The authors consider the term lentiginocardiomyopathic syndrome suitable for this rare clinical and genetic entity. The authors check patients with lentiginocardiomyopathic syndrome regularly after 6-month intervals. In two children they recorded progression of the heart disease.
