Subaortic
Subaortic VSD
|
| This is a series of angiograms of the left ventricle in LAO projection showing a puff of contrast into the right ventricle through the interventricular septum. A similar collection of contrast is noted in the the main pulmonary artery just to the left of the aorta. This high VSD is in the position of the membranous septum and thus represents a mebranous ventricular septal defect..

Transposition of the Great Vessels Aortic Valve is Anterior
|
| This is an angiogram of the RV, showing an anteriorly placed aorta, a VSD filling the LV, and a posteriorly positioned smaller MPA. The catheter courses via the IVC into the RV. The findings are consistent with TGA and in this case a D-TGA, though it is impossible to identify the position of the aortic valve in relation to the PA in this lateral projection. An associated VSD and subpulmonary stenosis and or PS is implied by the small sized PA.

Anomalous Origin of the Coronary Artery from the MPA

Aortic Arch
Aortic Arch – Pseudoaneurysm
|
| This image represents a combination of plain film CXR and the correlative thoracic aortogram in a 38 year old patient, 13 years after an MVA. There is an aneurysmal bulge at the level of the isthmus, representing a traumatic aneurysm at the characteristic location of the ligamentum arteriosum. The P-A and lateral chest X-ray shows an enlarged and unusually shaped aortic knob and the angiogram confirms the pseudoaneurysm of the aorta. 35178c Courtesy of Laura Feldman MD. code CVS aorta artery thorax trauma |

Isthmus
Aortic Interruption – Severe Coarctation
|
| 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 |

Traumatic Dissection of the Abdominal Aorta wit Loss of Perfusion of the Left Renal Artery
|
| These images represent a traumatic dissection of the abdominal aorta caused by a compression injury to the abdomen. The angiograms in a and b shows what appears to be a complex tear of the aorta with a dissection and then a subtotal obstruction of the aorta distally. The CTscan shows (c) the dissection to better effect, with a subtotal narrowing of the aorta distally. Note also the injury of the left renal artery on the angiogram as well as the lack of perfusion of the left kidney on the CT scan.
