Arterial EMBOLism After Catheter Ablation of Atrial Fibrillation (EMBOL AF)
The EMBOL-AF is a multicenter, international, observational study designed as a retrospective registry that will investigate the characteristics of systemic arterial embolic events after treatment of atrial fibrillation by catheter ablation. Due to the retrospective nature of the study, the registry is specially focused on cerebral embolism (stroke and TIA) because these are not only the most frequent and clinically relevant but also the most susceptible to underreporting. However, all embolism associated to AFAbl will be included. This study will gather all clinically relevant aspects and data of all cases of arterial embolism that have occurred over the last 5 years in the centers that will participate in the registry. Based on these reported cases, the incidence, management and outcomes of embolic events (particularly stroke and TIA) will be studied.
• Systemic arterial embolism (stroke, TIA or any other symptomatic event) after catheter ablation for AF or left atrial macroreentrant atrial tachycardia or left atrial flutter that have occurred between 1st january 2017 and 31st july 2023.
• The embolic event must be associated with the ablation procedure, therefore, it must have occurred during the procedure or during the first 7 days after it, during hospital stay or after discharge.
