Coronary artery bypass graft (CABG) procedure within the 6 months prior to the index ablation procedure. Awaiting cardiac transplantation or other cardiac surgery within 12 months following the initial ablation procedure. Presence of any type of implantable cardiac defibrillator (with or without biventricular pacing function). Documented thromboembolic event (stroke or transient ischemic attack) within the past 6 months (180 days). Documented left atrial thrombus on imaging.
