A new approach to "anatomic" repair of transposition of the great arteries.
Furthermore, the unknown vasodilator may flow to the systemic arteries without metabolization, and may induce systemic fistulas in similar fashion.
The aorta was 2.5 cm in diameter and its branches, along with the coronary arteries, were normal.
Retrospective review of the cases using these criteria identified 26 of the 27 intramural arteries with no false positive diagnoses.
One patient had 2 major aortopulmonary collateral arteries and required collateral ligation at the same time.
All patients had coronary changes, and six patients had giant aneurysms and severe stenotic lesions in each coronary arteries.
In such patients, the inflated balloon may compress the tunnel and compromise the flow of blood into the coronary arteries.
In both normal and defective hearts, however, the arterial duct is smaller than both the left and right pulmonary arteries.
