Aortic calcification in a patient with hutchinson-gilford progeria syndrome.

We present chest radiographs, echocardiographic image, and selective coronary angiogram of an 18-year old patient with Hutchinson-Gilford progeria syndrome.

Ring-calcification of giant coronary artery aneurysm of an 11-year-old child with history of kawasaki disease.

We present radiographic images of ring-calcification of a giant aneurysm of the left main coronary artery in a child, 7 years after the initial diagnosis of Kawasaki disease, as well as acute medical management and surgical bypass of the obstructed left anterior descending coronary artery.

Right aortic arch with anomalous left subclavian artery and left-sided patent ductus arteriosus (vascular ring) in an extremely low-birth-weight infant.

We present three-dimensional reconstructed images of the vascular ring of a 4-day-old extremely premature neonate which were obtained utilizing multidetector computer tomography. This is a unique case of early detection of Kommerell's diverticulum and vascular ring in an extremely low-birth-weight infant using this noninvasive technology.

Experimental evaluation of a new transcatheter vascular embolization device in the swine model.

Purpose: To evaluate a new transcatheter device suitable for arterial embolization in an animal model.

Materials And Methods: A new prototype self-expanding braided embolic device (Embolizor), consisting of nitinol wire strands fixed at either end with platinum-iridium bands and covered with a film of polyethylene, was deployed through 5-F diagnostic catheters into renal artery branches in five swine. Standard stainless-steel spring coils were deployed in other renal branches and served as controls.
