A case of a 42-year-old patient with anomalous origin of the left main coronary artery from the pulmonary artery who delivered three times with no complications: presentation, diagnosis, and review.

An anomalous origin of the left coronary artery (LCA) from the pulmonary artery or Bland-White-Garland (BWG) syndrome is a rare congenital cardiac anomaly, which is unusual to survive to adulthood if left uncorrected. The authors report an unusual case of a multiparity patient who delivered several times without any complications presenting at the age of 42 years with recurrent dyspnea on exertion in which echocardiographic findings of diastolic flow near the origin of the pulmonary valve were suggestive of anomalous origin of the LCA. A CT angiography confirmed that the left main coronary artery arises from the undersurface of the pulmonary flow close :o its origin and gives rise to a left anterior descending (LAD) and left circumflex arteries.
