Interventional Electrophysiology in Children: A Single-Center Experience
Mosaed, Pasha; Dalili, Mohammad & Emkanjoo, Zahra
Abstract
Objective: Ablation techniques of cardiac arrhythmia in children have significantly progressed in the past
decade; however, the number of pediatric ablations is still significantly lower than that in adults. Accordingly,
there is less information regarding the success rate and complications in this age group.
Methods: All pediatric ablations conducted between March 2005 and February 2011 at Rajaie Heart Center
were studied. Abolishing the arrhythmia source by the end of procedure was considered as success.
Recurrences before hospital discharge and those thereafter were named early recurrence and late recurrence,
respectively.
Findings: A total of 125 catheter ablations were performed for 112 patients. Of them 118 (94.4%) procedures
were successful. The success rate was significantly higher in the patients with atrioventricular nodal reentry
tachycardia (AVNRT). Of 105 patients who continued follow-up program, 7 (6.7%) cases experienced
recurrence; the recurrence rate was inversely dependent on the patients’ body size (P-value <0.05). There
was no mortality. Five cases were complicated during or early after the procedure, all the complications were
cured completely.
Conclusion: Therapeutic electrophysiology in children is an effective and relatively low-risk method. The
recurrence and complication rates are similar to those reported in adults. Considering our results and the
previous reports, pediatric patients with serious arrhythmia should not be deprived from ablation and should
not be exposed to long-term toxic drugs.
