Impact of Irrigated Contact-Force Sensing on Fluoroscopy Exposure and Efficiency in Pediatric AVNRT Ablation

The authors aimed to evaluate the safety, efficacy, and procedural characteristics of irrigated contact-force (CF) sensing catheters compared to conventional non-contact-force catheters in pediatric patients undergoing radiofrequency ablation for atrioventricular nodal reentrant tachycardia (AVNRT). The study found that CF-guided ablation resulted in significantly shorter procedure times, reduced fluoroscopy exposure, and higher acute procedural success rates, suggesting it is a safe and effective treatment option for pediatric AVNRT. However, differences in recurrence rates should be interpreted cautiously due to potential confounding factors.
