Study Description

Atrial fibrillation (AF) and atrial flutter (AFI) increase the risk of thromboembolic events by promoting clot formation in the left atrium (LA). Transesophageal echocardiography (TEE) is routinely used to exclude the presence of an LA thrombus before AF/AFI ablation or cardioversion. So far, it has not been established what is the optimal combination of noninvasive parameters for thromboembolic risk stratification in this setting. The present study is aimed to compare the prevalence of LA thrombus in patients on different anticoagulant regimens, identify predictors of LA thrombus and validate the newly developed CHA2DS2-VASc-AF-GFR score (and to compare its predictive value in LA thrombus identification with those of the CHA2DS2-VASc and the CHADS2 scores).

The study protocol all patients with AF or AFl in whom TEE will be performed (to assess their eligibility for cardioversion or ablation), hospitalized in a participating center during study period.
