Assessment

Primary outcomes

-Incidence of embolism during perioperative period
-Existence or non-existence of atrial thrombus just before the ablation, detected with transesophageal echocardiography or intra-cardiac Echocardiography

-Incidence of life threatening bleeding during the perioperative period
-Incidence of bleeding or embolism during the perioperative period and within 6 months after operation
-Number of days of hospitalization
-Incidence of ischemic stroke (fatal/non-fatal),systemic embolism, pulmonary embolism,acute myocardial infarction,TIA or vascular death (including hemorrhagic death),all cause mortality and their composite endpoint
-NCB(net clinical benefit)measured with the composite endpoint consisting of stroke,systemic embolism,pulmonary embolism,acute myocardial infarction,all cause mortality and major hemorrhage
