Safety and efficacy of cryoablation vs. radiofrequency ablation of septal accessory pathways: systematic review of the literature and meta-analyses

Does cryoablation compared to radiofrequency ablation improve safety and efficacy in patients with septal accessory pathways?

P

Population

Patients with septal accessory pathways (APs)

I

Intervention

Cryoablation

C

Comparator

Radiofrequency ablation (RFA)

O

Outcome

Efficacy rates and rate of atrioventricular block (AVB)

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.
