Abstract
Anomalous origin of the left coronary artery from the pulmonary artery (Bland-Garland-White syndrome) may produce myocardial ischemia, infarction and death in infancy. Some patients develop satisfactory coronary artery collaterals and are relatively asymptomatic into adulthood. Very little is known about their myocardial perfusion patterns. Three young adults with this condition were studied using stress 201Tl myocardial imaging. ECG in 2 patients demonstrated old anterolateral myocardial infarctions. Preoperative stress exercise tests were positive in the 3 patients. Marked perfusion abnormalities were found in the proximal anterolateral wall in all patients and 1 patient also had a posterolateral defect. Postoperatively, all stress tests returned to normal. Tl imaging demonstrated improvement in ischemic areas, but old scars persisted.
