Very-long-chain acyl-CoA dehydrogenase (VLCAD) deficiency is a severe defect of mitochondrial fatty acid oxidation characterized by hypertrophic cardiomyopathy, pericardial effusion, steatosis, and hypoglycemia, often resulting in death by 4-5 months of age. The onset of cardiomyopathy and pericardial effusion is insidious and sudden, necessitating early diagnosis and intervention to prevent death. A family affected with this defect is described in which dietary therapy with medium-chain triglycerides (MCT) was associated with rapid reversal of these severe clinical symptoms. Diagnosis by acylcarnitine analysis in the neonatal period can provide the opportunity for early clinical intervention. Prenatal diagnosis from amniocytes by enzymology or in vitro analysis of the fat oxidation pathway with deuterated fatty acid precursors has also been successful and permits intervention at birth. Of 10 affected children, 7 untreated cases died within the first several months while the remaining 3 cases survived when treated with medium-chain triglycerides as the major source of dietary fat.

Pericardial effusion and cardiomyopathy in the first year of life point to a fatty acid b-oxidation defect as underlying disease after exclusion of infectious causes. We report two patients with the early-onset, cardiac phenotype of very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency; in one patient, severe pericardial effusion was the predominating symptom. Because specific noninvasive treatment is available in fatty acid b-oxidation defects that reverses cardiomyopathy and pericardial effusion, early diagnosis is essential to adjust therapy accordingly.

Multiple acyl-CoA dehydrogenase deficiency (MADD) is a rare autosomal recessive defect of the electron transfer flavoprotein or ubiquinone oxidoreductase, resulting in abnormal fatty acid, amino acid, and choline metabolism, leading to metabolic acidosis, hypoglycemia, "sweaty-feet" odor, and early neonatal deaths. This report presents a child diagnosed with this disease at birth by newborn screening using the mass spectrometer, who died suddenly at the age of 6 months. The echocardiogram revealed pericardial effusion, thickened ventricular musculature, and insufficiency of both the atrio-ventricular valves. The autopsy showed immense cardiomegaly, fatty infiltration, and hypertrophy of the ventricles. This is the first detailed case report of clinico-pathological correlation of MADD in an infant and brings into light a rare form of cardiomyopathy as a differential diagnosis in critically ill patients.

Very long-chain acyl-CoA dehydrogenase deficiency (MIM 201475) is a severe defect of mitochondrial energy production from oxidation of very long-chain fatty acids. This inherited metabolic disorder often presents in early neonatal period with episodes of symptomatic hypoglycemia usually responding well to intravenous glucose infusion. These babies are often discharged without establishment of diagnosis but return by 2-5 months of age with severe and progressive cardiac failure due to hypertrophic cardiomyopathy with or without hepatic failure and steatosis. An early diagnosis and treatment with high concentration medium chain triglycerides based feeding formula can be life saving in such patients. Here, we report the first diagnosed and treated case of Very long-chain acyl-CoA dehydrogenase deficiency in Oman. This infant developed heart failure with left ventricular dilation, hypertrophy and pericardial effusion at the age of 7 weeks. Prompt diagnosis and subsequent intervention with medium chain triglycerides-based formula resulted in a reversal of severe clinical symptoms with significant improvement of cardiac status. This treatment also ensured normal growth and neurodevelopment. It is stressed that the disease must be recognized by the pediatricians and cardiologists since the disease can be identified by Tandem Mass Spectrometry; therefore, it should be considered to be included in expanded newborn screening program, allowing early diagnosis and intervention in order to ensure better outcome and prevent complications.
