Anomalous Left Coronary Artery from the Pulmonary Artery (ALCAPA) in Children

  • A congenital coronary artery anomaly in which the left coronary artery arises from the pulmonary artery rather than its usual origin from the aorta. This condition is one cause of poor cardiac function in infancy.

    For in-depth visual and audio information on this condition, visit the Boston Children's Hospital Multimedia Library.

    ALCAPA is a very rare heart defect that occurs as a result of the left coronary artery forming abnormally. Instead of connecting to the aorta, as in a normal heart, it connects to the pulmonary artery.
