Key result
TEE detects 100% of right atrial thrombi, outperforming TTE and altering anticoagulation or surgical management.
Why the study?
The diagnostic accuracy and impact on treatment of transesophageal echocardiography compared to transthoracic echocardiography for right atrial thrombi were unclear.
Does transesophageal echocardiography improve the diagnosis and management of right atrial thrombi compared to transthoracic echocardiography in patients with right atrial thrombi?
Population
20 patients with right atrial thrombi
Comparison
Transesophageal echocardiography vs transthoracic echocardiography
Design
Observational case series

Negative TTE misses most right atrial thrombi; leaves open whether routine TEE improves detection or outcomes.

Does transesophageal echocardiography improve the diagnosis and management of right atrial thrombi compared to transthoracic echocardiography in patients with right atrial thrombi?
Absolute Event Rate: 100% vs 30%
Transesophageal echocardiography is significantly more sensitive than transthoracic echocardiography for detecting right atrial thrombi and frequently alters clinical management, supporting its routine use when this condition is suspected.
Schwartzbard et al. (1999) conducted an observational in Right atrial thrombi (n=20). Transesophageal echocardiography vs. Transthoracic echocardiography was evaluated on Identification of right atrial thrombi. Transesophageal echocardiography identified right atrial thrombi in 100% of cases compared to 30% with transthoracic echocardiography, leading to changes in anticoagulation or surgical management.
