title: [Lipomatous hypertrophy of the interatrial septum versus lipomatous hypertrophy of the intervenous tubercle].
abstract: The lipomatous hypertrophy of the interatrial septum is a clinicopathological entity characterized by an accumulation of fat, not encapsulated but circumscribed in the atrial septum, over the fossa ovalis, and protruding into the right atrium; its thickness exceeding 15 mm. It is clinically associated with atrial electric abnormalities such as disorders of the atrial conduction and supraventricular arrhythmias, difficulty of the venous return and sudden death. In 1669 Lower described at the entrance to the right atrium, between the venae cavae, there is a tubercle formed by an accumulation of fat, covered over with muscular fibres that protrudes into the right atrium, which be called intervenous tubercle. The aim of this work is to find out the normal morphology of the intervenous tubercle and to find out whether or not lipomatous hypertrophy of interatrial septum is related to it in some way, because both coincides anatomically.
