Pathology of the Pulmonary Vascular Tree

Abstract

The case to be reported is characterized by stenosis of the ostium infundibuli of the right ventricle and biventricular origin of the aorta. Certain of the anatomic features of the heart in this case are similar to those of the Eisenmenger complex. One difference between the two conditions is that in the case herewith reported subpulmonary (infundibular) stenosis existed, while in the Eisenmenger complex there is no anatomic barrier to pulmonary blood flow, either in the heart or great vessels. On these gross anatomic differences seem to depend the differences in structure of the intrapulmonary arteries in the two conditions.
