Figure 4. AF Termination by ablation of a Stable RA Rotor.

Figure 4

A. Isochrones show a RA rotor and concurrent LA focal beat during persistent AF. B. Spatially constrained rotational center locus. C. Ablation lesions at lateral RA rotor on patient specific geometry (performed 2 hours after initial recording of rotor). A total of 11 lesions were applied (shown), with AF termination to sinus rhythm at 5.5 minutes. The red lesion indicates where ablation terminated AF. D. Electrograms AF terminating to sinus rhythm with localized ablation at rotor (total duration 5.5 minutes) (ECG lead I, intracardiac electrodes in RA, LA and CS). E. Isochrones of sinus rhythm. After ablation, the patient remains AF-free at 12 months on implanted cardiac monitor. Scale bar 1 cm.
