Congenital Diseases of the Aorta

Anomalous Origin of the Coronary Artery from the MPA

This injection into the base of the aorta showing filling of a dilated right coronary artery, collateral flow through the septal perforators, into a dilated LAD and then into the main pulmonary artery. (MPA) This is a case of anomalous origin of the left coronary from the MPA.

Coartcation of the Aorta

Aortic Interruption at the Level of the Isthmus

The most obvious finding in this CXR (a) with pleuro-parenchymal changes is not the most significant. In image (b) the highlighted ribs reveal rib notching characteristic of coarctation of the aorta. The lateral examination (c) in this instance is not helpful. In the early phase of the angiogram(d), there appears to be complete interruption of the aorta with a large left subclavian artery acting as a collateral pathway. The sbsequent images e, and f, show progressive filling of the isthmus and distal thoracic aorta. The coarcatation becomes apparent characterised by a “3” sign. 35107c Courtesy Laura Feldman MD code CVS artery aorta thorax coarctation rib notching bone collateral
