Causes of Early Mortality After Catheter Ablation of Atrial Fibrillation
Authors' conclusion
AF ablation procedure has a 90-day mortality of 0.22%, and the most common cause of early mortality was sudden death. The majority (73.3%) of early mortality was not directly associated with a procedural complication, and the mortality rate due to complications associated with the AF ablation procedure was low at 0.06%.
