Abstract:
Transesophageal echocardiographic and computed tomographic imaging in a patient with lipomatous hypertrophy of the interatrial septum and advanced left bundle branch block are presented. Transesophageal echocardiography demonstrated a thickening of the atrial septum sparing the fossa ovalis region. Computed tomographic scan at the level of the interatrial septum showed a mass of fat density, and the HIS bundle electrogram showed an advanced infra-his block after intravenous ajmaline. We stress the utility of transesophageal echocardiography in this disorder, and the possible relationship between lipomatous hypertrophy of the interatrial septum and conduction disturbances.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
