“…However, despite this technological progress in the field, conventional ablation of septal APs can sometimes be challenging. 7 Prolonged RFCA at high-power settings can lead to steam pop, which can be devastating. Cryoenergy can be useful; however, it has been implemented rather to minimize the risk of atrioventricular block and it is actually associated with higher recurrence rates when compared to standard RFCA.…”

“…endo þ epicardial) or using very high energy. 11 Furthermore, the coronary sinus and its branches can be stenotic or occluded, as in already treated patients, or too small to be entered by ablation catheter, as in children. Furthermore, radiofrequency delivery in such a delicate site can be associated with risk of venous thrombosis/occlusion, wall damage with pericardial effusion, and coronary artery injury.…”

Introduction: The aim of the study was to revise our more recent experience about epicardial posterior-septal accessory pathways radiofrequency transcatheter ablation in children and young patients using a transvenous approach through the coronary sinus, to understand if new mapping and ablation technologies can increase success rate and safety. Methods and results: Twenty children (mean age 13 ± 3 years) with epicardial posterior-septal accessory pathways (14 in coronary sinus and 6 in the middle cardiac vein) underwent radiofrequency transcatheter ablation with CARTO-3® system with help of the CARTO-Univu® module. Acute success rate was 73%. No patient was lost to follow-up (mean time 11.4 ± 9 months). The recurrence rate was 19%. Two patients underwent a successful redo-procedure; the overall long-term success rate was 65%. Navistar® catheter presented the highest acute success rate in the coronary sinus. Navistar SmartTouch® was the only catheter that did not present recurrences after the acute success, and it was successfully used in two patients previously unsuccessfully treated with a Navistar ThermoCool®. Acute success rate was 79% without image integration with angio-CT, while it was 63% after the introduction of CARTO-Merge®. Conclusion: Epicardial posterior-septal accessory pathways can be definitively eliminated by transvenous radiofrequency transcatheter ablation in more than half of the cases in children. Acute success rate does not seem to depend on catheters used, but contact-force catheter seems to be useful in cases with recurrences. Image integration with cardiac-CT does not increase success rate, but it is useful to detect coronary sinus alterations to better guide ablation strategy.
