Clinical presentation:
Female aged 5 weeks. In heart failure since aged 2 weeks. Minimal cyanosis. Loud systolic murmur.

The heart is significantly enlarged. The curve of the right heart margin is elongated and pronounced. The left side is a single curve to the cardiac apex apart from a density at the site of the posterior portion of the aortic arch. There is plumonary plethora with vessels extending towards the peripheral 1cm zone and visible veins crossing the right basal artery branches.

A catheter has been inserted from right brachial artery to the aorta. The pulmonary arteries have filled from a large ductus arteriosus. Both arrows point to an atretic ascending aorta and there is filling of coronary arteries, visible origin near the arrow-head in the lateral view.

These views show the length of the aorta and its atretic ascending part. The coronary arteries are again shown, projected across the descending aorta in the 'posterior' view.

Clinical presentation:
Female aged 16 days. Cyanosis and distress.

The catheter from the right brachial artery to the aorta fills an undersized atretic aorta and the coronary arteries. There is no indication of flow across the aortic valve. There is no pulmonary artery opacification.
