Anomalous origin of the left coronary artery: angiographic and myocardial perfusion scintigraphic correlates.
We studied a patient with an anomalous left coronary artery arising from the pulmonary artery by using conventional angiographic and myocardial imaging techniques. Myocardial imaging with radioactive 201thallium confirmed the significance of resting Q waves, and the defect in anterior perfusion coupled with the presence of thallium in the pulmonary outflow tract during exercise underscored the dynamic nature of the ischemic response to exercise in this syndrome.
