Multiple saccular congenital aneurysms of the atria causing persistent atrial tachyarrhythmia in an infant. Report of a case successfully treated by surgery.

Abstract

A 5-month-old infant presented with persistent tachyarrhythmia, cardiomegaly, and an abdominal mass. Cardiac catheterization and cineangiocardiograms revealed multiple aneurysms of the atria. These were removed successfully at surgery, whereupon normal sinus rhythm returned. The abdominal mass proved to be a hamartoma of the liver.
