Atrioventricular node reentry tachycardia in pediatric patients

Experience and Results During Transition from Radiofrequency Ablation to Cryoablation for Treatment of Pediatric Atrioventricular Nodal Reentrant Tachycardia

“…Atrioventricular nodal reentrant tachycardia (AVNRT), a common form of paroxysmal supraventricular tachycardia (SVT) in pediatrics, accounts for 13% of SVT in children and is more prevalent in adolescence 1,2 . While this type of tachycardia is not life‐threatening, it does affect patients' quality of life 3 .…”

“…Since then, RF ablation has evolved into the treatment of choice for many different tachyarrhythmias in young patients (1)(2)(3)(4)(5)(6)(7)(8). However, despite the success of RF ablation, there are reported safety and efficacy concerns that have been raised.…”

“…However, despite the success of RF ablation, there are reported safety and efficacy concerns that have been raised. Most notably, RF ablation treatment for patients with atrioventricular nodal re-entrant tachycardia (AVNRT), Wolff-Parkinson-White (WPW) syndrome, and other SVTs carries a definite risk for atrioventricular (AV) block because lesion creation within the region of the septum is close to the AV node or His bundle (6,9,10). Also, RF catheter ablation of septal accessory pathways (APs) has been identified as technically challenging in children due to the setting of small cardiac dimensions (3).…”

Transcatheter Ablation of Supraventricular Tachycardias in Pediatric Patients

“…The use of RF energy has increased greatly during the past 20 years and RF catheter ablation has become a safe and effective procedure for treatment of supraventricular and ventricular arrhythmia in children and adults [1][2][3][4][5][6][7][8][9][10]. RF energy is a power source well suited to place focal lesions.…”
