Cryoablation Highly Effective and Safer than RF Ablation in Treatment of Non-Atrial Fibrillation Arrhythmias

Dr Ellenbogen provides data from different peer-reviewed published sources which show that cryo therapy is as efficacious as RF for the treatment of AVNRT yet with a much lower risk of inadvertent AV block. Specifically he recommends the use of the 6mm cryo catheter : "If you want to get the same results as RF with a 95%+ success rate and same low recurrence rate use the 6mm Medtronic CryoCath catheter".

Treating AVNRT and Other Perinodal Arrhythmias with CryoTherapy: The Heart Rhythm Society's Grand Rounds on Ablation with Dr Peter L. Friedman

In light of the procedural success achieved with RF ablation, why should electrophysiologists include CryoTherapy in their treatment options? That is the central question which Dr Friedman addresses in this presentation.

Referring to the high acute and chronic success rates achieved in the FROSTY trials, Dr Friedman demonstrates the value of cryo energy in the treatment of AVNRT and other perinodal arrhythmias. Features such as CryoMapping, which allow electrophysiologists to test a potential site before creating a permanent lesion, offer a level of safety that practitioners welcome when treating arrhythmias located near critical structures in the heart.

In this highly informative presentation, Dr Friedman also refers to his own clinical practice to offer valuable tips on optimizing success in the treating AVNRT and septal accessory pathways and making the most effective use of CryoMapping.
