摘要: This study examined the role of left atrial (LA) appendage wall velocity (LAAWV) measurement in addition to LA size for noninvasive assessment thrombogenesis patients with fibrillation (AF) and normal plasma D-dimer levels. In 58 non-valvular AF patients, LAAWV volume index (LAVI) were determined by transthoracic echocardiography. flow severity spontaneous echo contrast (SEC) transesophageal was strongly correlated (r = 0.82), LAVI weakly (r = −0.37). As SEC increased, decreased (p 34 mL/m2), but 17 18 (94 %) had LAAWV < 10 cm/s. Severe found 3/20 LAVI, all them showed The is clinically relevant quantitatively assessing
