Cohort
Key result
Pre-procedural transoesophageal echocardiography detected left atrial thrombus in 1.9% of patients undergoing atrial fibrillation ablation, with no thrombi found in those without clinical risk factors.

May support selective omission of pre-procedural TEE in low-risk AF ablation patients; leaves open need for randomized confirmation.

What is the incidence and what are the clinical predictors of left atrial thrombus detected by pre-procedural transoesophageal echocardiography in patients undergoing atrial fibrillation ablation?
Pre-procedural transoesophageal echocardiography to screen for left atrial thrombus prior to atrial fibrillation ablation may be safely omitted in patients without clinical risk factors for stroke.
McCready et al. (2010) conducted a cohort in Atrial fibrillation (n=635). Transoesophageal echocardiography (TOE) was evaluated on Incidence of left atrial thrombus. Pre-procedural transoesophageal echocardiography detected left atrial thrombus in 1.9% of patients undergoing atrial fibrillation ablation, with no thrombi found in those without clinical risk factors.
