Balloon-based technologies, including cryoballoon and laserballoon, offer promising strategies for achieving complete electrical isolation of pulmonary veins in paroxysmal atrial fibrillation.
This review discusses balloon-based technologies (cryoballoon and laserballoon) for achieving pulmonary vein isolation in patients with paroxysmal atrial fibrillation.
Electrical isolation of the pulmonary veins still remains one of the major objectives during catheter ablation of atrial fibrillation. In patients with paroxysmal atrial fibrillation, balloon-based technologies hold great promise to simplify the approach to successful pulmonary vein isolation. While the cryoballoon represents the only true 'single-shot' technology, the laserballoon allows real-time endoscopic visualization of the pulmonary vein antrum during energy delivery. Either technology aims at complete electrical isolation, requiring continuous transmural lesion sets encircling the pulmonary veins. Strategies to confirm and to improve upon the efficacy of pulmonary vein isolation are the key to acute and long-term clinical success and will be reviewed in this article.
Wißner et al. (Sun,) conducted a review in Paroxysmal Atrial Fibrillation. Balloon-based Pulmonary Vein Isolation (cryoballoon and laserballoon) was evaluated. Balloon-based technologies, including cryoballoon and laserballoon, offer promising strategies for achieving complete electrical isolation of pulmonary veins in paroxysmal atrial fibrillation.
