3. Figure 1
An illustration depicting the principal design change between the AFA and the AFA-ST cryoballoons. As shown, the length of the distal tip (L) of the AFA-ST cryoballoon is ~40% shorter than that of the AFA balloon (8 mm vs 13 mm, respectively), thereby allowing farther withdrawal (d) of the inner lumen circular mapping catheter through the inner lumen of the cryoballoon to a more proximal location within the pulmonary vein ostia. AFA = Arctic Front Advance; AFA-ST = Arctic Front Advance-Short Tip.

4. Figure 2
Assessment of TT-PVI by the number of PVs per patient. The frequency of recording TT-PVI in 1 PV per patient (97% vs 83%; P < .001), in 2 PVs per patient (88% vs 62%; P < .001), and in 3 PVs per patient (64% vs 40%; P < .001) was greater using AFA-ST versus AFA. While there was a trend toward improved recording of TT-PVI in all PVs per patient (34% vs 25%; P = .072), this did not reach statistical significance. AFA = Arctic Front Advance; AFA-ST = Arctic Front Advance-Short Tip; PV = pulmonary vein; TT-PVI = time to pulmonary vein isolation.

5. Figure 3
Cumulative freedom from recurrent atrial arrhythmias after cryoballoon ablation of atrial fibrillation. A Kaplan-Meier curve illustrating the cumulative freedom from recurrent atrial arrhythmias after cryoablation using the AFA vs the AFA-ST cryoballoons, including the number of patients at risk. AFA = Arctic Front Advance; AFA-ST = Arctic Front Advance-Short Tip.
