Key result
2D echocardiography identifies atrial septal lipomatous hypertrophy as a distinctive echo-dense thickening averaging ~21 mm.
Why the study?
Lipomatous hypertrophy of the atrial septum was primarily diagnosed at autopsy, but interest centered on its association with supraventricular arrhythmias and sudden death.
Can two-dimensional echocardiography reliably diagnose lipomatous hypertrophy of the atrial septum in vivo?
Observational (n=17)
Can two-dimensional echocardiography reliably diagnose lipomatous hypertrophy of the atrial septum in vivo?
Two-dimensional echocardiography provides a distinctive, non-invasive method for diagnosing lipomatous hypertrophy of the atrial septum, a condition previously diagnosed primarily at autopsy.

Supports echocardiographic features for lipomatous hypertrophy diagnosis in older adults; hypothesis-generating pending prospective validation.
Fyke et al. (1983) conducted an observational in Lipomatous hypertrophy of the atrial septum (n=17). Two-dimensional echocardiography was evaluated on Echocardiographic features and clinical associations. Two-dimensional echocardiography identified lipomatous hypertrophy of the atrial septum as a distinctive echo-dense globular thickening with a mean thickness of 21 mm.
