title: Unusual origin and course of the left pulmonary artery.
abstract: An infant with a cardiac murmur was found to have a patent arterial duct and an anomalous left pulmonary artery. The duct was surgically ligated at the age of 8 months, and she remained free of cardiac or respiratory symptoms up to her death at 6 years from an unrelated intestinal condition. An anomaly was discovered at post mortem examination; the left pulmonary artery arose from the right pulmonary artery and passed behind the trachea to enter the left lung. We describe and illustrate the anatomic features of this well-recognized entity, discuss the embryological substrate, and refer to the clinical implications.
