The anomalous origin of the left coronary artery from the pulmonary artery, or Bland-White-Garland syndrome, is a rare congenital coronary anomaly that results in altered myocardial perfusion and left-right shunt. Ninety percent of patients with this syndrome die within the first year of life if the condition is left untreated. Diagnosis of this abnormality in adulthood is even rarer. We describe the cardiac catheterization and coronary computed tomography angiography findings of a recently diagnosed 27-year-old patient who underwent surgical correction.

(A and B) Coronary CT angiography. The left main coronary artery (LMCA) originated from the pulmonary artery and measured 7.3 mm in diameter. The left anterior descending artery (LAD) surrounded the apex of the left ventricle and measured up to 6.8 mm in diameter. The left circumflex artery (LCx), which is of great importance, exhibited ectasia in its proximal third and measured up to 6 mm in diameter. The right coronary artery (RCA) originated from the right coronary sinus and measured up to 8 mm at its largest diameter.
