Pressure-Guided cryoablation of pulmonary veins in atrial fibrillation: A fast and effective strategy.

<h4>Background</h4>Cryoballoon ablation of atrial fibrillation (AF) involves successful electrical pulmonary vein isolation (PVI). Pulmonary vein (PV) ostial occlusion with cryoballoon is classically assessed using PV angiography. A pressure-guided technique to assess ostial occlusion has been evalu... View More
