“…According to Lee et al study [ 11 ], it is a common complication. Compared to the present results, in Melo et al [ 17 ] the study procedure-related complications were observed among 12% of children with clinically documented SVT who underwent CA and in 11.7% of pediatric patients in the study conducted by Hafez et al [ 5 ].…”

Background: In contrast to adults, in whom cardiac rhythm disorders are mainly conditioned by coronary artery disease, in children, arrhythmias are most often associated with inherited heart disorders. Catheter ablation (CA) has an important role in the management of cardiac arrhythmias, in adults and children. The aim of the study was to assess and compare the efficacy and safety of CA in children and adults with preexcitation syndrome. Methods: The study population comprised 43 adults and 43 children diagnosed with a Wolff-Parkinson--White syndrome (WPW). The mean age of the study population was 41 ± 15 years for adults and 14 ± 2.5 years for children. In all patients, an electrophysiological study and CA were performed. Analysis with respect to the procedure duration, fluoroscopy exposure time, location of accessory pathways (AP), immediate success rate and complications were performed. Results: Electrophysiological study revealed the most frequent presence of left-sided AP (56% in children and 70% in adults). The mean procedure duration was 96 ± 36 min and 106 ± 51 min in children and adults, respectively (p = NS). The mean fluoroscopy duration was 8.5 ± 4.3 min and 5.9 ± 5.8 min in children and adults, respectively p < 0.05. The CA procedure was successful in 40 out of 43 (93%) adults and in 36 out of 43 (83.7%) children (p = NS). In 2 (4%) children minor complications occurred. Conclusions: Ablation in children and adults are equally effective with respect to short-term clinical observation.

“…Recurrences make the greatest contribution to the structure of long‐term results after RFA of arrhythmias. Several follow‐ups in pediatric population show that the recurrences after primary successful RFA occurred in 4.9%–29.2% 7,10–17 . The period of recurrence after primary RFA was 0.5 months (IQR 0.1–2.0) ‐ from 1 day to 6 months in our study.…”

Background: Radiofrequency ablation (RFA) is the standard method of treatment for tachyarrhythmias in school children, and it leads to complete recovery in children without structural heart disease. However, RFA in young children is limited by the risk of complications and unstudied remote effects of radiofrequency lesions.Objective: To present the experience of RFA of arrhythmias and the results of followup of younger children. Materials andMethods: RFA procedures (n = 255) were performed in 209 children with arrhythmias from 0 to 7 years old. The arrhythmias were presented with atrioventricular reentry tachycardia with Wolff-Parkinson-White (WPW) syndrome (56%), atrial ectopic tachycardia (21.5%), atrioventricular nodal reentry tachycardia (4.8%), and ventricular arrhythmia (17.2%). Results:The overall effectiveness of RFA, considering the repeated procedures performed due to the primary ineffectiveness and recurrencies, was 94.7%. There was no mortality associated with RFA in patients, including young patients. All cases of "major" complications are associated with RFA of the left-sided accessory pathway and tachycardia foci and are represented by the mitral valve damage in three patients (1.4%). Tachycardia and preexcitation recurred in 44 (21%) patients. There was a correlation between recurrences and parameters of RFA (odds ratio 0.894; 95% confidence interval: 0.804-0.994; p = .039). Reducing the maximum power of effective applications in our study increased the risk of recurrence. Conclusion:The use of the minimum effective parameters of RFA in children reduces the risk of complications, but increases arrhythmia recurrence rate.

“…Previous reports demonstrated that complete AV block was limited to patients with AVNRT and those undergoing ablation of septal pathways, both right and left sided [18,19]. CA therapy also has an increased rate of complications if it is made in small children, due to particularities such as limitation of vascular access, reduced cardiac dimensions, and potential anatomical variations due to congenital heart disease [20]. On the other hand, in paediatric patients with body weight above 15 kg, the risk of severe complications does not exceed the risk seen in adults, in whom the rate is 1-3% [5].…”
