Slow pathway elimination for atrioventricular nodal reentrant tachycardia with the 8-mm tip cryoablation catheter: an 18-month follow-up study

Purpose The 9-French 8-mm tip cryoablation catheter confers a high rate of acute slow pathway (SP) elimination and an acceptable short-term outcome in patients with atrioventricular nodal reentrant tachycardia (AVNRT). The aim of this study was to investigate the long-term outcome of patients treated with this electrode in this indication.
