Real time 3-dimensional transesophageal echocardiography is more specific than 2-dimensional TEE in the assessment of left atrial appendage thrombosis

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Left atrial appendage thrombosis (n=110). Intervention: Real-time 3-dimensional transesophageal echocardiography (RT3DTEE) vs. 2-dimensional transesophageal echocardiography (2DTEE). Primary outcome: Refinement or change of diagnosis of left atrial appendage thrombosis.

Key result

Real-time 3D TEE changes or refines LAA thrombosis diagnosis in ~24% of patients vs 2D TEE.

n=110

Why the study?

Does RT3DTEE improve the diagnostic assessment of left atrial appendage thrombosis compared to 2DTEE in patients undergoing transesophageal echocardiography?

Does RT3DTEE improve the diagnostic assessment of left atrial appendage thrombosis compared to 2DTEE in patients undergoing transesophageal echocardiography?

Population

110 consecutive patients (mean age 64, 33.6% female) indicated for detection of intraatrial thrombus who underwent both 2D and real-time 3D transesophageal echocardiography.

Intervention

Real time 3-dimensional transesophageal echocardiography (RT3DTEE)

Comparator

2-dimensional transesophageal echocardiography (2DTEE)

Outcome

Diagnostic value in the assessment of left atrial appendage thrombosis (refining or changing the definite diagnosis of thrombosis)surrogate

Limitations

No real thrombus was found in the study cohort.
RT3DTEE is not 100% sensitive or specific in thrombi identification.
RT3DTEE did not provide additional diagnostic value in patients where 2DTEE image quality was poor.
RT3DTEE did not help in a substantial portion of patients in whom 2DTEE was not diagnostic, mostly due to poor image quality
RT3DTEE is not 100% sensitive or specific in thrombi identification

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

RT3DTEE provides additional diagnostic value over 2DTEE for assessing left atrial appendage thrombosis, primarily by better differentiating muscular trabeculae from true thrombi.

Marek et al. (2012) conducted a cross-sectional in Left atrial appendage thrombosis (n=110). Real-time 3-dimensional transesophageal echocardiography (RT3DTEE) vs. 2-dimensional transesophageal echocardiography (2DTEE) was evaluated on Refinement or change of diagnosis of left atrial appendage thrombosis. Real-time 3-dimensional transesophageal echocardiography refined or changed the diagnosis of left atrial appendage thrombosis in 26 of 110 patients (23.6%) compared to 2-dimensional TEE.
