[Hypocalcemic dilated cardiomyopathy: rare cause of heart failure].

Hypocalcemic dilated cardiomyopathy is a rare cause of heart failure in adults. We report a case in a 19-year-old woman who developed congestive heart failure induced by severe chronic hypocalcemia disclosing primary hypoparathyroidism. Complete regression of the clinical signs was achieved with vitamin-calcium treatment, but left ventricular systolic dysfunction persisted eight months after treatment.
