Abstract

Deficiency rickets due to maternal hypovitaminosis D cause hypocalcaemia in infants, which may be complicated by dilated cardiomyopathy (DCM) with myocardial dysfunction. Calcium is central in myocardial contraction coupling, and hypocalcemia decreases myocardial contractility. However, dilated cardiomyopathy (DCM) due to hypocalcemia in infants has been rarely reported. Correction of hypocalcemia was associated with resolution of congestive heart failure and the left ventricular (LV) geometry and systolic function. We report the case of an infant who presented deficiency rickets due to maternal hypovitaminosis D, complicated by convulsion and dilated cardiomyopathy, with good improvement under treatment with calcium and vitamin D.
