Key result
Catheter ablation in infants and toddlers has improved in success and complication rates with 3D mapping systems, though long-term effects of lesions remain a concern.

What are the current treatment strategies, success rates, and complication rates of catheter ablation in infants and toddlers?
Catheter ablation in infants and toddlers is increasingly successful and safe, particularly with 3D mapping, but long-term data on ablation lesions are still needed.
Answers are grounded in this paper and cite their sources.
3D mapping may warrant cautious consideration for infant ablation; leaves open long-term lesion effects for prospective study.
Since the introduction of transcatheter ablation in the late 1980s, there has been significant technical development. With a very high success rate and low complication rate, ablation has now become the standard of care in children and adults. However, long-term data remain insufficient and the application of ablation therapy in small children is debatable. In this review, current treatment strategies and results in toddlers and infants will be discussed. There has been improvement in success rate and complication rate for ablation in small children. Technological advancements in non-fluoroscopic electroanatomical mapping systems (3D systems) have led to the reduction of radiation and have facilitated ablations in complex cases. However, long-term effects of ablation lesions in small children remain a potential concern.

Asakai et al. (2015) conducted a review in Arrhythmias requiring catheter ablation. Catheter ablation was evaluated. Catheter ablation in infants and toddlers has improved in success and complication rates with 3D mapping systems, though long-term effects of lesions remain a concern.
