Neonatal ventricular tachyarrhythmias in medium chain acyl-CoA dehydrogenase deficiency.
We describe an unusually severe case of medium chain acyl-CoA dehydrogenase (MCAD) deficiency in a term female neonate, who presented at 12 h of age with lethargy, poor feeding, hypoglycemia and ventricular tachyarrhythmias. While arrhythmias are common in other disorders of fatty acid beta-oxidation, ventricular tachyarrhythmias have rarely been reported with MCAD deficiency in childhood. Since the results of newborn metabolic screening are usually not available within the first 3 days of life, our case highlights the need for health care professionals to be made aware of this early and uncommon but potentially fatal presentation of MCAD deficiency.
