Vitamin D deficiency presenting with cardiogenic shock in an infant

A 2-month-old child was referred as a case of dilated cardiomyopathy with cardiogenic shock. On evaluation, hypocalcemia secondary to severe vitamin D deficiency was found. There were no clinical or radiological features of rickets. The child had developed multiorgan failure due to cardiogenic shock at the time of admission and could not be saved despite adequate ventilatory and pharmacologic support. Hypocalcemia should be considered as an important differential diagnosis in cases of dilated cardiomyopathy in infants.
