title: Prolapsing large aneurysm of the atrial septum simulating a right atrial mass.
abstract: An unusual case of a large, prolapsing atrial septal aneurysm in a patient with an otherwise normal heart is described. The aneurysm caused right atrial obstruction and resulted in a "tumor effect." The patient experienced debilitating symptoms for years before receiving an appropriate diagnosis and curative surgical treatment.
