RT Journal Article SR Electronic T1 Life threatening coronary artery spasm in childhood Kimura's disease JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP e5 OP e5 DO 10.1136/heart.84.2.e5 VO 84 IS 2 A1 H Horigome A1 T Sekijima A1 S Ohtsuka A1 M Shibasaki YR 2000 UL http://heart.bmj.com/content/84/2/e5.abstract AB A 13 year old boy is described with hypereosinophilia associated with Kimura's disease, who showed repeated life threatening syncopal attacks during daily activities or at rest. Coronary arteriography demonstrated small aneurysms with irregular vessel walls of both coronary arteries, and the absence of organic stenotic lesions. Infusion of a minimal dose of ergonovine into the right coronary artery induced severe spasm of the vessel. Ventricular fibrillation recurred even after administration of nifedipine and isosorbide was started, but was completely inhibited by prednisolone.
