Figure 5. AF Driver Associated Post-Surgical AF recurrence, Treated with Catheter Ablation (A) Near Posterior Box set.

Figure 5.

. High density voltage mapping (5,000 points) reveals a nearly complete posterior wall box (gray; < 0.1 mV) with a small low voltage zone (yellow circle) at the inferior border. (B) AF mapping revealed a driver at this site. (C) Radiofrequency ablation closed the gap and terminated AF (yellow box). This patient was free of AF and AT 1 year after ablation off anti-arrhythmic medications D. AF Driver Associated with SRAF, with Durably Isolated Posterior Wall and Pulmonary Veins. High density map (4,000 points) shows isolated PW and PVs (gray; <0.1 mV). (E) 64-pole basket catheter. (F) AF driver (correlating with yellow circle) on anterior left atrium outside surgical lesion sets, where (G) Ablation (red tags) terminated AF. This patient was free of AF and AT 1 year after ablation off anti-arrhythmic medications.
