title: Giant interatrial septal aneurysm mimicking a left atrial mass.
abstract: Interatrial septal aneurysm (IASA) consists of redundant atrial septal tissue, which bulges into either the left or the right atrium. The clinical implications of this entity are not entirely clear; however, if it is associated with other cardiac abnormalities such as patent foramen ovale and atrial septal defects. It may assume significance by increasing the risk of cardioembolic events such as stroke. We present a case of an individual with giant IASA detected by transesophageal echocardiography, which was mimicking a left atrial mass on transthoracic echocardiography. This case emphasizes the superiority of transesophageal imaging over transthoracic echocardiography for this clinical entity.
