Different surgeons and institutions have varying results. ASO is not suited for all patients. And an ASO cannot be performed in patients who come to medical attention at an older age, or who have severe pulmonary valve abnormalities.

Rare problems are obstruction at the site of connection of the pulmonary artery to the right ventricle, producing Pulmonary Stenosis, and sometimes leak of the new aortic valve - Aortic Regurgitation. A second operation has hardly ever been necessary for these complications. The other kind of operations for TGA are the Atrial Switch Procedures . Read more about them.
