Hypocalcemia is a less known but treatable cause for dilated cardiomyopathy, leading to severe heart failure in children. Cardiogenic shock related to hypocalcemic cardiomyopathy is a rare event. We describe 5 infants presenting with cardiogenic shock over 3 years, who were found to have severe hypocalcemia as a sole cause of myocardial dysfunction. The patients responded to calcium and vitamin D supplementation promptly and left ventricular systolic function normalized within months of treatment. In any case of cardiogenic shock, hypocalcemia should be included in the differential diagnosis and must be investigated.
