Key result
Infant radiofrequency ablation shows normal atrial tissue electrophysiology and no necrosis 12 years post-procedure.
Why the study?
Long-term effects and potential adverse outcomes after radiofrequency ablation in infants are not well characterized.
Does radiofrequency ablation in an infant cause long-term myocardial electrical activity reduction or necrosis?

Does radiofrequency ablation in an infant cause long-term myocardial electrical activity reduction or necrosis?
Radiofrequency ablation in a 2-month-old infant did not result in long-term post-ablation necrosis, showing normal electrical activity of the atrial tissue 12 years later.
Supports cautious use of infant RFA based on one case; leaves open need for prospective pediatric data.
The article presents a long-term follow-up of the patient who underwent an intracardiac electrophysiological study (EPS) and radiofrequency ablation (RFA) of focal tachycardia at the age of 2 months. 12 years after the indexed procedure, Wolff-Parkinson-White (WPW) syndrome was diagnosed and required repeat RFA procedure. The atrial map of the first ablated zone was reconstructed using non-fluroscopic mapping system. EPS reported the absence of myocardial electrical activity reduction zones. There were no damages after the indexed ablation. Our findings suggested the normal electrical activity of the atrial tissue in the long-term period following the indexed RFA. This clinical case reports the absence of post-ablation necrosis and successful restoration of the electrical activity of the myocardium with the child’s growth.

Dzhaffarova et al. (2019) conducted a case report in Focal tachycardia and Wolff-Parkinson-White (WPW) syndrome (n=1). Radiofrequency ablation (RFA) was evaluated on Myocardial electrical activity and post-ablation necrosis. Radiofrequency ablation in an infant showed no post-ablation necrosis and normal electrical activity of the atrial tissue 12 years after the indexed procedure.
