Why the study?
Does cryoablation provide safe and effective ablation in patients with accessory pathways adjacent to the normal conduction system?
Does cryoablation provide safe and effective ablation in patients with accessory pathways adjacent to the normal conduction system?
Cryoablation allows for safe ablation of accessory pathways near the AV node or His bundle by using ice mapping to predict acute effects before creating an irreversible lesion.
May support cryoablation near the conduction system in select cases; leaves open need for randomized comparison to radiofrequency.
Cryoablation appears to be a safe and effective technique for ablation of APs close to the AV node or His bundle because of the ability to predict the acute effects of ablation with ice mapping before creation of an irreversible lesion.
