Daño reversible del nodo auriculoventricular durante la crioablación de una vía accesoria parahisiana en un niño con preexcitación intermitente. Rev. argent. cardiol.

Reversible Damage of the Atrioventricular Node during Cryoablation of a para-Hissian Pathway in a Child with Intermittent Pre-excitation Syndrome Damage of the atrioventricular node (AVN) is one of the potential complications in radiofrequency ablation of para- Hissian accessory pathways. Cryotherapy, with reversibility potential at non extreme temperatures, may be an alternative in the ablation of these pathways. A child with intermittent pre-excitation syndrome, para-Hissian accessory pathway and a crisis of supraventricular paroxistic tachycardia was subjected to electrophysiological assessment, and cryoablation allowed removing the accessory pathway with preserved AVN integrity.
