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
Figure 3 A Fluoroscopic views of the successful isolation site.B. Intracardiac electrocardiogram of the successful ablation
site.
ABL = ablation; CS = coronary sinus; HRA = high right atrium; LAO = left
anterior oblique; RAO = right anterior oblique; RSPV = right superior
pulmonary vein
