[Surgical treatment of the abnormal origin of the left coronary artery from the pulmonary artery. The Bland-White-Garland syndrome].

Seven children aged 6 weeks to 9 months with anomalous left coronary artery originating from the pulmonary artery and a 46-year-old female patient with pronounced formation of collaterals in Bland-White-Garland syndrome and left-right shunt were operated between July 1976 and February 1984. All children had already experienced left ventricular anterior wall infarction. Angiocardiography in 6 cases established the diagnosis, in one case echocardiography had proved sufficient. In the children, close-to-origin ligation of the left coronary artery was done after median sternotomy. One child succumbed postoperatively whereas in all others preoperative cardiac insufficiency regressed satisfactorily. In the adult female close-to-origin cutting of the left coronary artery was followed by aorto-coronary venous bypass.
