Transient left ventricular dysfunction in Churg Strauss syndrome: a case report.

A 42 year old woman was admitted to our hospital for investigation of eosinophilia. There were no findings from the physical examination of the lungs and heart. The echocardiography showed a segmental hypokinesia of the interventricular septum and the apex causing left ventricular dysfunction with an ejection fraction 45% and mild pericardial effusion. Cardiac magnetic resonance was performed, for detection of lesions associated with the underline disease, using electrocardiogram-triggered T2-weighted and T1-weighted multislice spin-echo images (before and after an intravenous bolus of gadolinium).The analysis of T2-weighted images revealed increased signal on the mid part of interventricular septum, suggesting myocardial oedema. In the delayed-enhanced images, areas of late phase gadolinium enhancement (indicative of fibrosis) were identified in the mid part of interventricular septum. Methylprednisolone therapy was started. The patient had follow-up echocardiographic examination every month and on sixth month improvement of left ventricular dysfunction was shown with an ejection fraction 55%.In conclusion our case is a typical Churg Strauss Syndrome with characteristic myocardial involvement which improved after corticosteroid treatment. The cardiac magnetic resonance has significant role for early and accurate detection and differentiation of myocardial damage even in preserved cardiac wall motion and cavity size.
