OBJECTIVE: To determine if pediatric patients with a history of lone atrial fibrillation (AF) have other forms of supraventricular tachycardia (SVT) that may potentially trigger AF.
STUDY DESIGN: A multicenter review of patients with lone AF who underwent electrophysiology (EP) study from 2006-2011 was performed.
INCLUSION CRITERIA: age ≤21 years, normal ventricular function, structurally normal heart, history of AF, and EP study and/or ablation performed.
EXCLUSION CRITERIA: congenital heart disease or cardiomyopathy. Patient demographics, findings at EP study and follow-up data were recorded.
RESULTS: Eighteen patients met inclusion criteria. The mean age was 17.9 ± 2.2 years, weight was 82 ± 21 kg, body mass index was 27 ± 6, and 15 (83%) were males. Eleven (61%) were overweight or obese. Seven (39%) had inducible SVT during EP study: 5 atrioventricular nodal re-entry tachycardia (71%) and 2 concealed accessory pathways with inducible atrioventricular re-entry tachycardia (29%). All 7 patients with inducible SVT underwent radiofrequency ablation. There were no complications during EP study and/or ablation for all 18 patients. The mean follow-up was 1.7 ± 1.5 years and there were no recurrences in the 7 patients who underwent ablation. There were 2 recurrences of AF in patients with no other form of SVT during EP study.
CONCLUSIONS: Inducible SVT was found in 39% of pediatric patients undergoing EP study for lone AF. EP study should be considered for pediatric patients presenting with lone AF.
