Key result
Catheter cryoablation offers favorable lesion characteristics, cryomapping, and cryoadhesion, making it a suitable alternative to radiofrequency ablation for peri-nodal and pulmonary veno-atrial substrates.
Why the study?
Does catheter cryoablation improve efficacy and safety compared with radiofrequency ablation in patients with peri-nodal and pulmonary veno-atrial substrates?

This review discusses the efficacy and safety of catheter cryoablation compared to radiofrequency ablation for specific arrhythmic substrates.
Cryoablation may suit peri-nodal and veno-atrial substrates; leaves open randomized comparisons to radiofrequency ablation.
Catheter cryoablation (CRYO) is an alternative approach to radiofrequency (RF) ablation in the treatment of cardiac arrhythmias. The favourable lesion characteristics of CRYO and its unique properties of cryomapping and cryoadhesion make this newer approach especially suitable for the treatment of peri-nodal substrates, such as atrioventricular nodal re-entrant tachycardia and septal accessory pathway, and pulmonary veno-atrial substrate in atrial fibrillation. This review aims to present and discuss the data on the use of catheter CRYO for these substrates with special emphasis on its efficacy and safety compared with RF ablation.

Ngai‐Yin Chan (2015) conducted a review in Cardiac arrhythmias (atrioventricular nodal re-entrant tachycardia, septal accessory pathway, atrial fibrillation). Catheter cryoablation (CRYO) vs. Radiofrequency (RF) ablation was evaluated on Efficacy and safety. Catheter cryoablation offers favorable lesion characteristics, cryomapping, and cryoadhesion, making it a suitable alternative to radiofrequency ablation for peri-nodal and pulmonary veno-atrial substrates.
