Dilated cardiomyopathy and cardiogenic shock in a toddler with vitamin D deficiency: a case report
Abstract
Vitamin D deficiency is a common nutritional problem in exclusively breastfed infants. Dilated cardiomyopathy is a rare but potentially fatal complication of this condition. We describe a 15-month-old who presented with cardiogenic shock. Laboratory and radiographic findings were consistent with vitamin D deficiency. Metabolic parameters normalised within one week and echocardiography normalised by 19 months after supplementation. Although rare, severe vitamin D deficiency must be on the differential for young children presenting with new-onset dilated cardiomyopathy. Clinicians must maintain a high index of suspicion for vitamin D deficiency in at-risk populations to prevent potentially life-threatening complications.
