Conversion of Persistent Atrial Fibrillation After Radiofrequency Ablation by Ibutilide
1Consultant & Clinical Senior Lecturer in Cardiac Electrophysiology, Imperial College London.
Abstract:
Ablation of peristent AF remains challenging with questions unanswered about what the ideal next step after pulmonary venous isolation should be. Ibutilide is a highly effective class III agent for cardioversion of acute-onset atrial flutter and fibrillation, with limited clinical use due to risks of ventricular pro-arrhythmias. However, results from the on-going MAGIC-AF trial may re-invigorate its role in clinical electrophysiology as an invaluable adjunct to facilitate controlled substrate modification during ablation of persistent AF.
