Anomalous origin of left coronary artery from the pulmonary trunk in a mildly symptomatic adult female.

Anomalous origin of the left coronary artery from the pulmonary trunk, also known as Garland-Bland-White syndrome, is an extremely rare but potentially fatal congenital cardiovascular anomaly, and it often exists as an isolated condition. We hereby report an adult female who was admitted for mild chest discomfort and was accidentally diagnosed to have anomalous origin of the left coronary artery from the pulmonary trunk. This anomaly was simply repaired by using a bovine pericardial patch to obliterate the anomalous opening in the pulmonary trunk and a single coronary artery bypass graft. This report highlights the characteristic events of the anomaly in an adult with only mild symptoms.
