Myocardial involvement in systemic capillary leak syndrome: first demonstration by pathologic findings.

This case vignette relates the unknown association between systemic capillary leak syndrome, namely Clarkson's syndrome, and acute cardiac dysfunction. 'Central extra-corporeal life support (ECLS)' was needed for the management of an intractable cardiogenic shock. The acute cardiac condition completely resolved within few days. Pathology showed diffuse interstitial edema within the myocardium suggestive of cardiac involvement of the disease.
