The single catheter approach in conjunction with the Achieve catheter is currently standard practice in second\u2010generation cryoballoon ablation, yet circumferential mapping catheters are the gold standard for evaluating PV isolation (PVI). The study sought to validate the ostial PVI verified by an Achieve catheter alone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred fifty\u2010one paroxysmal atrial fibrillation patients undergoing PVI using exclusively 28\u2010mm second\u2010generation cryoballoons were enrolled. PV recordings were analyzed during (real\u2010time recordings) and after cryoballoon applications with 20\u2010mm Achieve mapping catheters, and subsequently validated by 20\u2010mm conventional circumferential mapping catheters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Out of 596 PVs, 576 (96.6%) were isolated using cryoballoons, and 20 required touch\u2010up ablation. PVI was verified during cryoballoon applications with real\u2010time monitoring in 299, and after applications in 280 PVs by Achieve catheters alone. The time\u2010to\u2010isolation was 27.2 \u00b1 22.0 seconds. Validation with standard circumferential mapping catheters confirmed ostial PVIs in 296 of 299 (99.0%) PVs that real\u2010time PVI was obtained during applications, and in 242 of 280 (86.5%) PVs that PV activities were not visible during applications and PVI was verified after the applications. The accuracy of ostial PVIs with Achieve catheters in PVs without obtaining real\u2010time PV recordings was 40\/47 (85.1%), 58\/65 (89.2%), 77\/79 (97.5%), 61\/81 (75.3%), and 6\/8 (75.0%) in left
