Complete absence of pulmonary veins

AbstractVarious types of pulmonary venous return abnormalities have been described in the literature. This report presents a case in which a 4‐h‐old neonate presented with cyanotic heart disease and respiratory distress. This neonate was subsequently shown to have complete absence of the pulmonary veins (CAPV), a previously undescribed malformation. The case summary describes the physical findings, radiographic and electrocardiographic features, cardiac catheterization data, and results from autopsy. A discussion of the case, theories of embryological etiology for this malformation, and differential diagnoses follow. Surgical treatment for CAPV is not yet possible.
