Case Report "Aorta Coarctation"

A 30-year-old woman complains of shortness of breath during exercise. The patient denies smoking or any previous lung problem. The physical examination reveals a systolic heart murmur and a pulse difference between arm and legs. An echo was performed and demonstrated normal left ventricular function, normal heart valves but a turbulent flow at proximal descending aorta. MR Angiography (MRA) of the aorta was requested for diagnosis of a suspected aortic coarctation.
The MRA was reconstructed with different techniques and confirmed the diagnosis of coarctation of the aorta. However, this also revealed an aberrant left subclavian artery. This diagnosis is an important point for surgical planning since reimplantation of the artery will be required. Thin maximum intensity projections (thinMIP) images (Fig. 1) illustrate the findings. In addition, Volume Rendering Technique (VRT) (Fig. 2) in different projections and colors demonstrates the vascular anomaly.
