Key result
Cardiac CTA identifies a large LAA thrombus missed by TEE.
Why the study?
Does 64-slice cardiac CTA improve detection of left atrial appendage thrombi compared to transesophageal echocardiography in patients with atrial fibrillation?

Does 64-slice cardiac CTA improve detection of left atrial appendage thrombi compared to transesophageal echocardiography in patients with atrial fibrillation?
This case highlights that 64-slice CTA may detect left atrial appendage thrombi missed by transesophageal echocardiography, suggesting a potential complementary role in pre-cardioversion or pre-ablation assessment.
No takes yet. Share an insight, caveat, or question.
TEE may miss large LAA thrombi seen on CT; this case leaves open whether CT augments TEE for detection.
Biria et al. (2008) conducted a case report in Paroxysmal atrial fibrillation and left ventricular dysfunction (n=1). Transesophageal echocardiography and 64-slice CT angiography was evaluated on Detection of left atrial appendage thrombus. Transesophageal echocardiography failed to detect a large left atrial appendage thrombus that was subsequently identified by 64-slice CT angiography in a 65-year-old man.
