One of the patients showed pulmonary lesion because of plexogenic arteriopathy of unknown etiology. The other 33 cases had congenital heart malformations. Macroscopic data as heart weight, thickness of the wall of the right ventricle and circumference of the pulmonary artery trunk were analized. Lesions developed in the pulmonary artery and its branches as well as those of the pulmonary veins are described. Different patterns of the hypertensive vascular disease are refered, emphasizing their evolution with the age of the patients. Some of the cases are particularly analized because of clinical, physiopathological or morphological peculiarities.
