However, comparative evidence regarding substrate\u2010specific outcomes with OIC versus non\u2010irrigated catheters (NIC) for supraventricular tachycardia (SVT) remains limited. This study compared acute ablation success (AAS) and recurrence after first\u2010time RFCA using OIC versus NIC, with particular emphasis on differential outcomes in atrioventricular re\u2010entrant tachycardia (AVRT) and atrioventricular re\u2010entrant tachycardia (AVNRT).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective cohort of consecutive patients undergoing first\u2010time RFCA for AVNRT or AVRT between 2017 and 2023 was analyzed. Patients were categorized by catheter type (OIC vs. NIC). Primary outcomes were AAS and SVT recurrence during 24\u2010month follow\u2010up. Multivariate logistic regression and Cox proportional hazards models were used for adjusted analyses.
