The incidence and severity of abnormalities of the coronary arteries were evaluated in 35 necropsy @entity1 with @entity1146 and an intact @entity67 . Right ventricular to coronary artery fistulous connections were found in more than 60% of the cases. All @entity1 with fistulous connections had histologic abnormalities of the coronary arteries. In 50% the lesions were mild, with medial and intimal thickening producing up to moderate @entity850 . In 50% there was loss of normal arterial wall structure and severe @entity543 or obliteration of the arterial lumen. The coronary arterial fistulas and histologic abnormalities were prevalent in those with underdevelopment of the tricuspid valve and right ventricular cavity but were not found in @entity1 with a normal or dilated tricuspid valve anulus. The @entity453 were found in more than 80% of @entity1 with a tricuspid valve/mitral valve ratio less than 1. A single coronary artery occurred in 6 @entity1 (17%) of this series. In 80% of those with 1 coronary artery arising from the other, the aberrantly arising coronary artery crossed anteriorly to the pulmonary artery and could be at risk in surgical attempts to reconstruct the right ventricular outflow. Aortography is recommended if the coronary arteries are not clearly delineated on @entity67 .
