This study was designed to determine the transesophageal echocardiography (TEE)-detected ineidence of left atrial (LA) thrombus and spontaneous echo contrast (SEC) in 100 patients with and without left ventricular systolic dysfunction with chronic nonvalvular atrial fibrillation (AF) not receiving anticoagulation. In addition, we investigated left atrial appendage (LAA) function. Group I consisted of 53 patients with normal left ventricular systolic function (left ventricular ejection fraction= 62±6%), group II of 47 patients with left ventricular systolic dysfunction (left ventricular ejection fraction= 40±5% ). LA thrombus w as present in 6 of 53 (I 1%) patients in group I and in 17 of 47 (36%) patients in group II. There was significant difference in the occurrence of LA thrombus between the groups (p
