Off-pump total arterial revascularization for anomalous origin of the left coronary artery from the pulmonary artery.

Anomalous origin of the left coronary artery from the pulmonary artery is a rare but potentially lethal congenital anomaly, especially if presented later in adulthood. We report a previously healthy young man who had a sudden cardiac arrest at a Zumba class, was resuscitated, and was successfully treated with off-pump total arterial revascularization and ligation of the left main stem of anomalous origin.
