Why the study?
Does extensive isolation improve freedom from atrial arrhythmia compared to individual isolation in patients undergoing 28-mm cryoballoon ablation?
Does extensive isolation improve freedom from atrial arrhythmia compared to individual isolation in patients undergoing 28-mm cryoballoon ablation?
Extensive isolation is superior to individual isolation for achieving long-term freedom from atrial arrhythmia using 28-mm cryoballoon ablation.
Should not yet change CBA practice; leaves open randomized confirmation of extensive isolation benefit.
Extensive isolation is superior to individual isolation for achieving freedom from atrial arrhythmia in long term follow-up by CBA. Evaluating PV diameter at the left atrial PV junction is essential for applying CBA.
