Association of common origin of the carotid arteries with anomalous origin of the left coronary artery from the pulmonary artery.
Common origin of the carotid arteries (COCA) is a common pattern of aortic arch vessels and is the single most common cause of tracheobronchial compression by a congenital cardiovascular anomaly. By no means all affected patients are symptomatic. Symptoms may range from recurrent pulmonary infections and "noisy respiration" to stridor and apneic spells. In our study of patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) we found a highly significant association of COCA with ALCAPA (85%), although no patient with ALCAPA in this study had evidence of tracheal stenosis documented in the hospital chart. As COCA is easily correctable, we suggest consideration of COCA during evaluation and surgery of patients with ALCAPA so that, if the patient also has symptoms possibly related to COCA, the artery can be suspended from the posterior wall of the sternum.
