Successful cryoablation of atrioventricular nodal reentrant tachycardia and coexisting accessory pathways without fluoroscopy

Abstract

The prevalence of coexistent AVNRT and AVRT has been rarely reported in the literature. The bypass tract is usually first targeted for ablation because of the concept that dual AV nodal physiology is more physiological for the heart than AP. In this paper, we briefly discuss that multiple supraventricular arrhythmia substrates can be successfully eliminated without fluoroscopy with the aid of electroanatomical systems.
