WHAT IS THE DIFFERENCE BETWEEN RF AVNRT ABLATION AND CRYO.

[Cleveland Clinic]

Radiofrequency is heat and cryo is freezing.  RF is more powerful but at the same time less forgiving in case something that wasn't supposed to be burned was.  On the other hand, cryo is less powerful and at the same time more foregiving.  For simple ablations with very well definced anatomy we like to use RF.  In the cases of complex ablations, where the pathways to be ablated are located very closely to other important structures, we tend to go with cryo.

Radiofrequency ablations produce tissue death through hyperthermic injury. RF ablation produces thermal injury through the use of alternating electric current

Cryoablation is an alternative to causing thermal injury to tissue through heating, cryoablation destroys tissue by delivering subfreezing temperatures via probes through which a cryogen is circulated.
