title: Anomalous origin of the left anterior descending coronary artery from the pulmonary trunk.
abstract: An extremely rare congenital abnormality is reported in which the anterior descending branch of the left main coronary artery arises independently from the pulmonary trunk in a young patient who presented with unstable angina. Its clinical presentation, angiographic identification and surgical treatment are described. It appears to be a distinct entity with few of the features of the classical form of anomalous origin of the left main coronary artery.
