Abstract
Lipomatous hypertrophy of the interatrial septum is a clinicopathological entity defined as an accumulation of fatty tissue exceeding 15 mm in thickness in the interatrial septum above the fossa ovalis. It is clinically associated with atrial electric abnormalities, interference with venous return, and sudden death. Transesophageal echocardiography is superior to transthoracic echocardiography for the study of the interatrial septum. We describe one case of lipomatous hypertrophy of the interatrial septum in which transesophageal echocardiography was used, we believe for the first time, to study the interatrial septal anatomy.
