title: Congestive heart failure caused by vitamin D deficiency?
abstract: We describe a child, 3.5 months old, with severe vitamin D deficiency, profound hypocalcaemia, hyperphosphataemia, dilated left ventricle, severely reduced myocardial contractility and congestive heart failure. She also had depressed thyroid function with subnormal thyroxine and non-detectable serum thyrotropin (TSH) levels. The child promptly responded to calcium infusions, conventional anticongestive therapy and calcitriol. She is now 3 years old and received no medication. Myocardial function is normal but she has motor delay. We believe that her transitory congestive heart failure was caused by severe vitamin D deficiency with profound hypocalcaemia.
