Key result
Transthoracic echocardiography, specifically the subcostal view, successfully identified an extremely rare case of isolated double atrial septum with persistent interatrial space in a 69-year-old man.

Subcostal TTE may detect rare double atrial septum; case reports leave open prevalence and clinical impact.
Double atrial septum is very rare atrial septal malformation which has double layered atrial septum with persistent interatrial space between the two atria. Clinically, most cases of this anomaly are asymptomatic unless manifest as thromboembolic complications, such as stroke, or transient ischemic attack, that thrombus may be originated from this interatrial space. We report a case of a 69-year-old man who was diagnosed with isolated double atrial septum by transthoracic echocardiography.

Kim et al. (2013) conducted a case report in Isolated double atrial septum (n=1). Transthoracic echocardiography was evaluated. Transthoracic echocardiography, specifically the subcostal view, successfully identified an extremely rare case of isolated double atrial septum with persistent interatrial space in a 69-year-old man.
