Atrial thrombus detection on transoesophageal echocardiography in patients with atrial fibrillation undergoing cardioversion or catheter ablation: A pooled analysis of rates and predictors
Key result
The pooled prevalence of left atrial thrombus detected by TEE was 1.3-1.8% before catheter ablation and 4.9-7.5% before electrical cardioversion in patients with atrial fibrillation.
Why the study?
Data needed summarizing on the rates and predictors of left atrial or left atrial appendage thrombus detection by TEE prior to electrical cardioversion or catheter ablation for AF.

Implication
The prevalence of left atrial thrombus in AF patients undergoing cardioversion or ablation varies by procedure type and OAC use, with clinical risk scores predicting thrombus presence.

Cite This Study
Noubiap et al. (2021) conducted a meta-analysis in Atrial fibrillation (n=56,660). Transoesophageal echocardiography (TEE) was evaluated on Left atrial thrombus/left atrial appendage thrombus (LAT/LAAT) detection. The pooled prevalence of left atrial thrombus detected by TEE was 1.3-1.8% before catheter ablation and 4.9-7.5% before electrical cardioversion in patients with atrial fibrillation.
