Sudden Unexpected Infant Death due to Fibroma of the Heart

Abstract

A 7-month-old previously healthy female infant was found dead in her crib by her mother shortly after having been laid down to sleep following the noontime feeding. Because the child did not suffer from an acute illness and no other evidence pointed to a cause of death, it was initially assumed by the police that she had died of sudden infant death syndrome. At autopsy, however, the cause of death was determined to be cardiac arrhythmia secondary to fibroma of the heart.
