Patient History

A 49-year-old female, 79 kg with native aortic coarctation.

Diagnosis

syngo DynaCT Cardiac images were used to rule out an aneurysm and to demonstrate the spatial relationship of the aortic coarctation. A rotational angiogram was acquired during normal respiration. Subsequently, a 3D image was generated identifying the optimal projection for the interventional procedure-stent implantation.

Protocol

5 sec rotational angiography, 130 projection images. Injection: Ascending aorta, 50 cc contrast, 150 cc total volume (1:2 dilution), injection rate 25 ml/sec, 1 sec X-ray delay.

Comments

syngo DynaCT Cardiac generated a three dimensional morphology of the aortic coarctation. Quantitative measurements of the stenosis, and identification of the optimal projection assisted in the successful intervention treatment and planning.
