Spontaneous coronary artery dissection in an adolescent man with systemic lupus erythematosus.

摘要

A 17-year-old adolescent man with a known immuno-logical diagnosis of systemic lupus erythematosus (SLE) and multisystem involvement was admitted for coronary angiography. An earlier echo cardiogram had shown regional wall motion abnormalities with significant hypo-kinesis of the mid-distal inferolateral wall and mild hypo-kinesis of the inferior wall of the left ventricle (LV). The LV diastolic function was pseudonormal. A magnetic resonance imaging (MRI) scan using a 2-D inversion recovery gradient-echo sequence (Fig. 1a,b) showed thinning of the obtuse marginal surface with a global LV ejection fraction of 48%.
