Congenital Solitary Left Atrial Mass

Abstract

Rhabdomyoma in the absence of tuberous sclerosis presenting as a large solitary atrial mass is an atypical finding. We hereby present images from an infant with a fetally diagnosed large left atrial mass with no evidence of mitral valve dysfunction who subsequently developed persistent arrhythmias requiring surgical resection of the mass in the neonatal period.

Keywords: arrhythmia; cardiac tumors; mitral valve; neonate.
