Anomalous origin of the left coronary artery from the pulmonary artery: collective review of surgical therapy.

Anomalous origin of the left coronary artery from the pulmonary artery is an extremely rare but potentially fatal congenital coronary anomaly. Prompt surgical reestablishment of a two-coronary system on diagnosis yields excellent results and allows progressive and nearly total myocardial recovery. Follow-up of all patients is required to assess the adequacy of repair and to exclude ongoing or recurrent myocardial insult.
