Cryoablation may be preferred for AVNRT to reduce fluoroscopy and eliminate heart block risk; leaves open direct comparison with radiofrequency in trials.
Cryoablation for AVNRT offers the advantage of cryomapping to avoid permanent damage to the normal conduction system, resulting in the absence of heart block.
Schwagten et al. (2010) studied this question.
