Risk of left atrial appendage thrombus in patients scheduled for ablation for atrial fibrillation: beyond the CHA2DS2VASc score

In patients scheduled for AF ablation, an LAA thrombus or dense echo contrast is a relatively common finding despite routine anticoagulant treatment. The addition of AF type and renal function to the CHA2DS2VASc score slightly improves thromboembolic risk stratification and may help identify patients who do not need preprocedural TEE.
