Irrigated\u2010tip catheter (ITC) ablation might offer an advantage in this setting but data about its use in patients below 18 years are scarce. The aim of this study was to compare an ITC approach to conventional catheter ablation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective analysis of all patients\u00a0&lt;18 years undergoing radiofrequency ablation (RFA) for right\u2010sided APs from 2004 to 2014 at our institution was performed. Patients either underwent an ITC approach in combination with 3\u2010D mapping (Group 1; n\u00a0\u00a0=\u00a0\u00a053) or a conventional non\u2010ITC approach (Group 2; n\u00a0\u00a0=\u00a0\u00a052). Study endpoints were acute procedural success, safety, and recurrence rate. A total of 105 mostly adolescent patients (56.2% male; median age 14 years) with 107 right\u2010sided APs were included.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevailing anatomic AP locations were right posteroseptal (44.9%), right anterior\/anterolateral (24.3%), and right lateral (13.1%). Acute success (94.3%\u00a0vs 94.2%) did not differ between the groups. One major complication (pericardial effusion) occurred in the non\u2010ITC group. Overall, freedom from AP recurrence was 94% at 4 years in the ITC group, and 81% at 4 years in the non\u2010ITC group (P\u00a0\u00a0=\u00a0\u00a00.04).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The use of ITCs in combination with 3\u2010D mapping system for ablation of right\u2010sided APs in adolescents has a high acute success rate, is safe, and associated with a significantly reduced recurrence rate compared to a non\u2010ITC\/conventional approach.
