BACKGROUND: The treatment of choice for atrioventricular nodal reentrant tachycardia (AVNRT) is catheter ablation of the atrioventricular nodal slow pathway. OBJECTIVE: The purpose of this study was to ascertain whether cryoablation (Cryo) with 6-mm-tip catheters is as effective as radiofrequency ablation (RF). METHODS: Patients who had catheter ablation for AVNRT between 2005 and 2008 were identified. The main outcome measure was overall success without the use of an alternative energy source and no recurrence. RESULTS: Two hundred eighty-eight procedures in 272 patients were identified; 184 were female (68%), and the mean age was 53 +/- 14 (17-88) years. There were 123 Cryo and 149 RF procedures. Cryo had a lower overall success rate (83% vs. 93%; P = .02). Mean procedure times were similar in both groups (90 minutes; P = .5). Fluoroscopy time was longer with Cryo: 16 (7-48) versus 14 (5-50) minutes (P = .04). Only one case of atrioventricular block was observed in the RF group (0.7%). Cryo was more expensive than RF ( pounds sterling 3141 vs. pounds sterling 2153). CONCLUSION: Even when delivering multiple lesions with 6-mm-tip catheters, Cryo is less effective than RF. RF is recommended as a first-line treatment, although the only major complication occurred in the RF group. Copyright 2010 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.
