Figure 1 A. Ablation points during the first procedure.B. Activation mapping during sinus rhythm demonstrated reconnection of the right superior pulmonary vein. The earliest activation site within a previous circumferential was found in the anterior carina area where the pulmonary vein was isolated during the initial procedure. The earliest activation in the left atrium was found at the insertion site of Bachmann’s bundle. C. Voltage mapping during repeated ablation without an apparent gap along the ablation line. RIPV = right inferior pulmonary vein, RSPV = right superior pulmonary vein
Figure 2. Activation mapping during pacing from the right superior pulmonary vein. The earliest activation site was at the posterior wall of the right atrium, opposite the right pulmonary vein carina. The earliest activation in the LA was similar to that during sinus rhythm, suggesting conduction over Bachmann’s bundle.
LA = left atrium, RA = right atrium

ABL = ablation; CS = coronary sinus; HRA = high right atrium; LAO = left anterior oblique; RAO = right anterior oblique; RSPV = right superior pulmonary vein
