Under pressure: paediatric hypertensive dilated cardiomyopathy secondary to renal artery stenosis.

Severe dilated cardiomyopathy in children may uncommonly be caused by abnormal loading conditions such as mid-aortic pathology and renal artery stenosis. Refractory hypertension and left ventricular dilatation with hypertrophy are important clues to reversible causes. We present a case of dilated cardiomyopathy in a child secondary to mid-aortic syndrome with renal artery stenosis.
