CHADS(2) score is predictive of left atrial thrombus on precardioversion transesophageal echocardiography in atrial fibrillation.
The goals of this study were to determine: 1) if the CHADS(2) score correlates with left atrial (LA) or left atrial appendage (LAA) thrombus on pre-cardioversion transesophageal echocardiography (TEE) in nonvalvular atrial fibrillation (NVAF); and 2) what, if any, components of the CHADS(2) score are most important in predicting LA/LAA thrombus. ⋯ In non-valvular atrial fibrillation, CHADS(2) is strongly associated with LA thrombus on TEE. Our findings suggest pre-cardioversion TEE may be unnecessary if the CHADS(2) score = 0. Of the components of the CHADS(2) score, CHF was the only independently associated risk factor which correlated with LA/LAA thrombus.
