Cryoablation : quel apport dans la prise en charge des tachycardies par réentrée intranodale ?

Radiofrequency ablation is the reference method for the interventional treatment of AV nodal reentrant tachycardias. Even if risks are low, one of the complications of radiofrequency ablation is auriculoventricular block. Cryoablation is an alternative to radiofrequency ablation. The most important advantage of this technique is a lack of permanent AV-block. This article reviews principles of cryotherapy, its main results in ablation of AV nodal reentrant tachycardias, its advantages and disadvantages. A proposal is made about its indications.
