Anomalous origin of left circumflex artery in a scimitar syndrome. A case report.

This report concerns a twenty-seven-year-old woman with scimitar syndrome of abnormal origin of the left circumflex artery from the pulmonary artery. Operation was performed to redirect the abnormal venous return to the left atrium and abnormal origin of the left circumflex artery to the aorta. Unfortunately, pulmonary hypertension with hemoptysis occurred nineteen months after the operation. A second angiogram showed total occlusion of the graft to the left circumflex artery and impaired left ventricle function, rather than thrombosis of the anastomosis to the scimitar vein, as the cause of pulmonary hypertension.
