Left Main Coronary Artery Compression by Right Ventricle-to-Pulmonary Artery Conduit Relieved by Anterior Translocation of the Right Pulmonary Artery.

Pulmonary artery translocation has been described as an alternative surgical strategy to treat anomalous aortic origin of the coronary artery from the wrong sinus of Valsalva. We describe another application of this strategy in a patient who underwent complete repair of pulmonary atresia with ventricular septal defect and presented years later with ischemic symptoms due to compression of the left main coronary artery by the right ventricular-to-pulmonary artery conduit. To our knowledge, this is the first application of the pulmonary artery translocation technique to treat such a problem.
