Study Arms:
- Group A - Standard Care (Type: ACTIVE_COMPARATOR): The operator will attempt to complete the WACA lesion set using standard techniques. These include ablating any obvious gaps in the lesion set, ablating at the WACA line in a location radial to the earliest PV signal measured by the Orion catheter situated within the PV, and guided by amplitude and dV/dt of signals along the WACA lesion set measured using the mapping catheter. If this fails the operator will resort to OSA as per their usual practice.
- Group B - Rhythmia mapping (Type: EXPERIMENTAL): The operator will form Rhythmia maps focussing on the region of the WACA line surrounding the non-isolated vein(s) whilst pacing from CS. This will be used as a means of targeting RF ablation to gaps in the WACA line (in addition to use of standard observation of signals as per group A). If this fails then the operator will resort to OSA as per their usual practice.

Based on this trial design, predict the completion outcome and termination type (if applicable).
