ABSTRACT
Objective To evaluate the role of transeso phageal echocardiography(TEE) before chemical or electric cardioversion for non-vulvular atrial fibrillation. Methods Forty-three patients, confirmed non-vulvular atrial fibrillation, undertook anticoagulation or anti-platelet therapy and transthoracic echocardiography and TEE less than 24-48 hours prior to cardioversion. Results Two thrombi in the left atrial appendage and three spontaneous echo contrasts in the left atrium were evidenced. After anticoagulation or anti-platelet therapy, 39 patients undertook cardioversion therapy. Among them,31 patients received drug cardioversion,success in 19,and failure in 12;8 patients received electric cardioversion,success in 6,and failure in 2. There were no thromboembolic events during the hospitalization. Conclusions TEE performed before cardioversion for atrial fibrillation is necessary to reduce the risks of thromboembolic events and to guide for anticoagulation therapy.
