Interrupted Aortic Arch: Ascending Aortogram
The ascending aorta was entered by performing a Brockenbrough procedure across the atrial septum. An anterior-posterior ascending aortogram demonstrates a cervical aortic arch and atresia of the aorta at the level of the isthmus. The left subclavian artery does not fill. The descending aorta fills via collateral vessels including prominent internal mammary arteries. The pressure in the ascending aorta was 152/97 mm Hg and in the descending aorta 94/83 mm Hg.
