Does cryoablation compared to radiofrequency ablation improve safety and efficacy in patients with septal accessory pathways?
While RFA offers higher efficacy for ablating septal accessory pathways, cryoablation provides a safer profile with a lower risk of AV block.
Studies of RFA for treatment of septal APs report higher efficacy rates than do studies using cryoablation, but a significantly higher rate of AVB.
Bravo et al. (Tue,) studied this question.
