Table 2. Transthoracic echocardiography parameters and associated valve pathology stratified by the presence of left atrial thrombus in the study population.

LA: left atrial; MR: mitral regurgitation; AR: atrial regurgitation; AS: atrial stenosis; TR: tricuspid regurgitation; ASD: atrial septal defect; SD: standard deviation; LV: left ventricular; EF: ejection fraction; RV: right ventricular
