Key result
Adenosine testing and reablation of dormant potentials after second-generation cryoballoon ablation increased the clinical success rate for atrial fibrillation to 84% vs 79% without testing.

May support adenosine testing after cryoballoon ablation; leaves open need for randomized confirmation before routine use.
Cohort (n=90)
Does adenosine testing and reablation of dormant potentials after second-generation cryoballoon ablation improve the clinical success rate for atrial fibrillation?
Absolute Event Rate: 84% vs 79%
Adenosine testing to identify and re-ablate dormant conduction after second-generation cryoballoon ablation may improve freedom from atrial fibrillation recurrence.
Kumar et al. (2015) conducted a cohort in Atrial fibrillation (n=90). Adenosine testing and reablation of dormant potentials vs. No adenosine testing was evaluated on Clinical success rate for atrial fibrillation. Adenosine testing and reablation of dormant potentials after second-generation cryoballoon ablation increased the clinical success rate for atrial fibrillation to 84% vs 79% without testing.
