Pulmonary artery partition: new method for correction of interrupted aortic arch.

We have successfully corrected interrupted aortic arch with ventricular septal defect by employing deep hypothermia and circulatory arrest, a median sternotomy incision, and a pulmonary arteriotomy. This simplified technique has the advantage of an abbreviated period of cerebral ischemia, with a relatively simple partitioning of the pulmonary artery.
