  Thromboembolism represents a significant complication arising from catheter ablation procedures despite its relatively low incidence in most cardiac arrhythmias. The overall risk of thromboembolism is approximately 0.6%, but it increases to 1.8%–2.0% in left-sided procedures. Thrombi may form on intravascular sheaths, radiofrequency (RF) lesions can be inherently thrombogenic, and preexisting thrombi may become dislodged. Most thromboembolic events occur within 24 hours post-ablation, with a heightened risk period extending to two weeks. While cerebral thromboembolism is most frequently identified clinically, emboli can also affect the pulmonary artery, coronary artery, or abdominal and peripheral vascular circulation. Management of cerebral embolism can be conservative or involve thrombolytic therapy or percutaneous intervention. Preventative measures for thromboembolism associated with catheter ablation include appropriate anticoagulation, optimal RF energy settings, external...
