Abstract:
Objective To explore the relationship between size,shape and function of the left atrium appendage (LAA) and its thrombosis in patients with atrial fibrillation (AF) by transesophageal echocardiography (TEE) to provide evidence for clinical risk assessment,prognosis evaluation and treatment guidance.Method Length,diameter,end-diastolic volume (EDV) and ejection velocity (PEV) of LAA were measured in 41 patients with AF,and thrombus in LAA was detected by TEE.Results Thrombus in LAA was detected in seven of 41 patients of AF (17%).No significant difference in size and EDV was found between the patients with and without thrombus,but there was significant difference in PEV between them (P
