Safety and Results of Cryoablation in Patients <5 Years Old and/or <15 Kilograms

Cryoablation of the right anteroseptal or midseptal accessory pathways in children: A 2‐year single‐center experience

“…Such case has also been recorded in the literature. 23 Our data indicate that cryoablation of right anteroseptal APs doses not achieve a higher success rate than that of right midseptal APs, which is different to Bar-Cohen et al's research findings. 20 Drago et al reported a better acute success rate in manifest APs compared with concealed APs.…”

“…Although samples like these are limited in number, it does suggest that cryoenergy can be applied to ablation of special cases like younger children. Such case has also been recorded in the literature . Our data indicate that cryoablation of right anteroseptal APs doses not achieve a higher success rate than that of right midseptal APs, which is different to Bar‐Cohen et al's research findings .…”

Catheter ablation of drug resistant supraventricular tachycardia in neonates and infants

“…However, until 2011, studies of TCA use in neonates and infants remained very limited [17,18]. The only publication on this topic is an international multicenter retrospective [12]. Those patients who had to undergo RFA due to failed TCA developed complications, while those who only underwent TCA had none.…”

“…Restrictions have also been placed on the use of RFA in smaller children since RFA lesions have been shown to have a progressing nature in animal studies [10], in addition to causing coronary ischemia and venous complications in infants [11]. In the recent years, use of transcatheter cryoablation (TCA) in children weighing less than 15 kg has been shown to be relatively complication-free [12]. This report summarizes our experience in using RFA and TCA to treat medically refractory SVT in neonates and infants.…”

Sustained tachyarrhythmia in children younger than 1 year of age: Six year single‐center experience

“…Radiofrequency ablation is a safe and effective method used for the definitive treatment of SVT in children . Recently, cryoablation has been used as a safe and efficacious alternative to RFA . Because infants and newborns are more prone to complications due to ablation, such as cardiac perforation, pneumothorax, AV block, and coronary artery perforation due to low bodyweight, its use is limited.…”
