LONG-TERM FOLLOW-UP ASSESSMENT OF POTENTIAL ADVERSE EFFECTS AFTER RADIOFREQUENCY ABLATION IN AN INFANT (A CLINICAL CASE)

Abstract
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.
