ABSTRACT
Congenital coronary artery anomalies are extremely rare causes of early cardiac failure. Several cardiac lesions are associated with coronary anomalies such as pulmonary atresia with intact ventricular septum. Isolated coronary ostial atresia is extremely rare and described in only a few published case reports. To our knowledge, there were two reports of bilateral coronary ostial atresia in which the entire coronary arterial system originated from the right ventricle without other intracardiac defects. We present a case of a full-term infant who presented with severely depressed biventricular function secondary to bilateral coronary ostial atresia.
ABSTRACT
Studies have been conducted on adults prescribed with methadone to determine the necessary frequency of QTc monitoring but no consensus has been reached and no similar research has been conducted in the pediatric population. The objective of this retrospective study was to determine the occurrence rate of QTc interval prolongation associated with methadone use in a pediatric oncologic population. In total, 18% of patients developed QTc interval prolongation. These patients had longer baseline QTc intervals and were on more QTc interval-prolonging medications. Our data suggest that these variables may be able to risk stratify patients who require more frequent monitoring.

Influenza is a cause of significant morbidity and mortality worldwide. Myocarditis is a rare complication of the virus and can vary widely in severity. The published cases of influenza B myocarditis in children tend to be severe with a high mortality rate. Current standard treatment of viral myocarditis is supportive care, although immunomodulatory therapies, such as steroids and intravenous immunoglobulin, are often used. T cells have been implicated in causing significant myocyte damage in myocarditis by leading to the downstream production of antibodies against viral and myocyte antigens; this has created a theoretical basis for the use of antithymocyte globulin to target T cells in these patients. We present a case of acute fulminant influenza B myocarditis in a pediatric patient that required mechanical circulatory support and improved only after treatment with antithymocyte globulin.
