Implication
Supports omitting LA imaging with single big cryoballoon PVI; leaves open randomized confirmation of durability and outcomes.
Structured PICO
Does the single big cryoballoon technique achieve acute pulmonary vein isolation in patients with paroxysmal atrial fibrillation?
P
Population
Patients with paroxysmal atrial fibrillation
I
Intervention
Single big cryoballoon technique for acute pulmonary vein isolation without left atrial imaging
O
Outcome
Electrical isolation of pulmonary veinssurrogate
The single big cryoballoon technique is highly effective for acute pulmonary vein isolation (98% success) without requiring left atrial imaging.
