Key result
TEE detects embolic left atrial papillary fibroelastoma missed by prior TTE.
Why the study?
A negative transthoracic echocardiography does not exclude the presence of cardiac tumors, and transesophageal echocardiography may better detect and characterize such tumors.
Does transesophageal echocardiography improve the detection of cardiac tumors compared to transthoracic echocardiography in patients with embolic strokes?

Does transesophageal echocardiography improve the detection of cardiac tumors compared to transthoracic echocardiography in patients with embolic strokes?
This case highlights that a negative transthoracic echocardiogram does not rule out a cardiac tumor, and transesophageal echocardiography should be considered in the workup of embolic strokes.
No takes yet. Share an insight, caveat, or question.
Negative TTE does not exclude cardiac tumors in embolic stroke; leaves open whether TEE improves diagnostic yield.
Cook et al. (2017) conducted a case report in Transient ischemic attacks and multiple embolic strokes (n=1). Transesophageal echocardiography (TEE) vs. Transthoracic echocardiography (TTE) was evaluated on Detection of cardiac mass/tumor. Transesophageal echocardiography successfully identified a rare left atrial papillary fibroelastoma as the source of embolic strokes after a negative transthoracic echocardiogram.
