Radiofrequency catheter ablation (RFCA) is a safe and effective treatment option for children with refractory supraventricular tachycardias. RFCA of right-sided accessory pathways (APs) continues to be challenging, resulting in lower success rates and higher recurrence rates. One of the reasons for a prolonged or failed procedure is mapping error and changes in cardiac anatomy. The right coronary artery (RCA) runs along the ventricular aspect of the right epicardial atrioventricular groove, and RCA mapping had been reported facilitating difficult right-sided AP RFCA in the pediatric population. We reported that microcatheter-assisted mapping during RFCA can improve localization of right-sided and some left-sided APs particularly in children with congenital heart disease.
