For physicians and cardiologists

Is your patient a good candidate for cryoablation? Currently, cryoablation is approved only for patients with supraventricular tachycardia. Studies have shown that the procedure is effective in the treatment of atrial fibrillation.

Generally, electrophysiologists who add cryoablation to their practice do so because it offers a very high level of safety. Features such as cryoadhesion (for greater stability) and cryomapping (for pre-ablation site-testing) contribute to its safety profile.

Cryoablation offers unique advantages:

  • A unique level of safety and precision when ablating near the AV node
  • Accurate site confirmation with cryomapping
  • Increased safety and ablation precision through cryoadhesion
  • Connective tissue matrix integrity is preserved thus maintaining the strength of the underlying tissue architecture
  • Well demarcated cryolesions that heal quickly
  • Cryolesions demonstrate minimal endothelial disruption which results in reduced incidence of thrombus formation
  • Reduced risk of collateral tissue injury when ablating near critical structures such as coronary arteries and the phrenic nerve

Advantages of using cryoablation to treat atrial fibrillation:

  • Reduced risk of thrombus formation
  • Reduced risk of phrenic nerve injury
  • No reports of pulmonary vein stenosis
  • No reports of atrial esophageal fistula, a dreaded complication reported with radiofrequency

In a canine model, when compared to an RF lesion, the cryo lesion demonstrates: minimal thrombus, an intact endothelial boundary; and complete fibrosis process.
