Balloon technology for catheter ablation of atrial fibrillation

While high percentage of acute isolation has been demonstrated in most patients with both balloon catheters, little data are available on the chronic durability of cryoballoon or laser balloon lesions. Our own data show that cryoballoon ablation and laser balloon ablation allow for durable PV isolation with the use of a single balloon. With maintained chronic isolation in most PVs, it may represent a significant step toward consistent and lasting ablation procedures.
