A retrospective study was undertaken to determine the spectrum of angiographic abnormalities of the coronary arteries in infants and children with pulmonary atresia, hypoplastic right ventricle, and right ventriculocoronary arterial communications. Twenty-nine patients with 67 angiographic examinations were reviewed; findings in seven patients were compared with those at autopsy. Twenty-seven (93%) of 29 patients had caliber abnormalities of the involved coronary arteries, including obstructive lesions in 20 (69%) of 29 and segmental dilatation in 16 (55%) of 29. Nine patients had interruption of the anterior descending artery and one had absent connection between the coronary arteries and the aorta. A single coronary artery was found in four of 29 patients. There was excellent correlation between clinical angiography and autopsy findings in seven patients. This study confirms the ability of high-quality clinical angiography to show significant abnormalities of the coronary arteries in infants and children with pulmonary atresia and ventriculocoronary communications.
开展了一项回顾性研究，以确定患有肺动脉闭锁、右心室发育不全及右心室冠状动脉交通的婴幼儿冠状动脉造影异常的范围。对29例患者的67次血管造影检查进行了回顾；将7例患者的检查结果与尸检结果进行了比较。29例患者中有27例（93%）受累冠状动脉存在管径异常，其中29例中有20例（69%）存在阻塞性病变，29例中有16例（55%）存在节段性扩张。9例患者前降支中断，1例患者冠状动脉与主动脉之间无连接。29例患者中有4例发现单支冠状动脉。7例患者的临床血管造影与尸检结果具有良好的相关性。本研究证实，高质量的临床血管造影能够显示患有肺动脉闭锁及心室冠状动脉交通的婴幼儿冠状动脉的显著异常。
