AF is associated with a fivefold increased risk of cardioembolic events; approximately 20% of all strokes are caused by AF. Pulmonary vein isolation (PVI) has become the first-line treatment for AF. However, PVI cannot eliminate the residual stroke risk. Current guidelines recommend that anticoagulation be continued in this specific group of patients, regardless of the presence or absence of AF. In this large AF population post-PVI, who are considered to be in an earlier stage of AF, it is unknown whether left atrial appendage closure (LAAC) offers an alternative to direct oral anticoagulant (DOAC) therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>The trial will be a prospective, randomised, multicentre non-inferiority study comparing two treatment strategies in AF patients after atrial ablation. Patients will be randomly assigned to either percutaneous LAAC (group A) or DOAC treatment (group B) in a 1:1 ratio; both sequential and concomitant planned ablation with or without LAAC are accepted. Randomisation will be conducted using web-based randomisation software. A total of 1012 participants (506 patients per group) will be enrolled. The primary effectiveness measure will be the occurrence of any of the specified events within 24 months after randomisation: stroke\/transient ischaemic attack\/systemic thromboembolism, cerebral haemorrhage, other major haemorrhages (Bleeding Academic Research Consortium \u22652), cardiovascular mortality and all-cause mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The study was approved by the Ethical Review Board of Shanghai Chest Hospital, China (KS(Y)20287).
