Hussein et al performed a registry study that examined controls and patients with mitral valve replacement who underwent AF ablation. [127] No cases of catheter entrapment or stroke were reported. Although most patients required more than one ablation, at last follow-up, 69% were arrhythmia-free and no longer taking antiarrhythmic medications. This provides evidence that AF ablation is safe in this group of patients. Of note, many patients had flutter and creation of a flutter line was one of the keys to success. [127]
