Left atrial appendage function study by transesophageal echocardiography

WU Changjun, XIAO Zhuying, FU Shiying, et al First Clinical College of Harbin Medical University, Haerbin 150001  
Objective To evaluate the predictive value of left atrial appendage (LAA) function in success of electrial cardioversion (ECV) in patients with nonvalvular atrial fibrillation (NVAF), and observe the course of the recovery of LAA systaltic function Methods To test blood flow wave patterns, peak emptying velocity (PEV) of LAA and left atrial spontaneous echo contrast (SEC) of left atrial appendage before ECV and after ECV 24 hours, 3 days and 1 week in 60 patients with NVAF by using transesophageal echocardiography (TEE) Results (1) Patients with LAAPEV20 cm/s had a ECV success rate of 75%, in contrast, LAAPEV20 cm/s had that of 30% (2) LAA blood flow wave patterns converted to a organized contraction patterns LAAPEV (2310 cm/s) was lower than that (3010 cm/s) before ECV (P0001); SEC could be generated in 8 patients, intensified in 11 patients Conclusion LAA mechanical activity prior to ECV is highly related to maintenance of sinus rhythm in NVAF, and LAA stunning developed a thrombogenic milieu Patients with atrial fibrillation should be given full anticoagulation to prevent thrombogenesis in left atrial and LAA
