A 6\u2010mm tip catheter was used in 64 patients and an 8\u2010mm tip catheter in 65 patients. All procedures were performed using a three\u2010dimensional electroanatomical mapping system (EAMS) (EnSite, Abbott\/St. Jude Medical Inc., St. Paul, MN, USA), with minimal or no fluoroscopy in most cases. Acute success, recurrence rates, procedural parameters, and complications were compared between groups. Of the 129 patients, 126 (97.7%) had typical AVNRT and 3 (2.3%) had atypical AVNRT. The mean procedure time was 151.9\u00a0\u00b1\u00a043\u00a0min, with no significant difference between groups. Acute success rates were 100% in the 6\u2010mm group and 98.5% in the 8\u2010mm group (\n                      <jats:italic>p\u00a0<\/jats:italic>\n                      &gt;\u00a00.05). The mean number of cryolesions was 8.5\u00a0\u00b1\u00a02.3 (6\u2010mm) and 9.0\u00a0\u00b1\u00a02.5 (8\u2010mm) (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&gt;\u00a00.05). Over a mean follow\u2010up of 31.4\u00a0\u00b1\u00a026 months, recurrences occurred in six patients (4.6%), all successfully re\u2010ablated. Long\u2010term success rates were 94.4% overall, with no significant difference between groups. No permanent complications occurred; transient AV block was observed in one patient (0.7%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both 6\u2010mm and 8\u2010mm CA catheters achieve high acute success and low recurrence rates in pediatric AVNRT with similar safety profiles.
