Case report reveals a large eustachian valve mimicking a divided right atrium on transesophageal imaging, highlighting the need for routine multiplane views.
Intraoperative use of transesophageal echocardiography (TEE) can detect a structure that is in reality a rare variant. We are reporting a case where we incidentally found large eustachian valve (EV) on transesophageal echocardiography which was missed on transthoracic echocardiography. It was giving right atrium two chamber appearance. We will recommend the importance of obtaining multiple echocardiographic views routinely during TEE to diagnose and differentiate such structures and its implications.
