Objective Radiofrequency ablation (RFA) has rapidly become the first-line therapy for children with supraventricular tachycardia (SVT). Recently, more attention has been given to the measurement of health-related quality of life (QoL) in children. The primary aim of this study was to determine if there is a change in the QoL in children with SVT pre and post RFA procedure using the Pediatric Quality of Life Inventory (PedsQL) cardiac inventory. In addition, the study discusses the impact of age, gender and variety of SVT mechanisms on the QoL.

Design, setting and patients All consecutive children with SVT referred for RFA at Mansoura University Children's Hospital were enrolled in this study. The PedsQL cardiac module questionnaire was given to the children/parents to be filled out before and 1 month following RFA procedure. Evaluated areas were physical, emotional, social, school and psychosocial function. The paired t test was used to test the difference between pre-time and post-time points for the study groups. Demographic and clinical data were collected.

Results The study sample consisted of 38 patients who underwent a successful ablation. The mean age of the patients at the time of RFA procedure was 12.4±5.3 years. There was a statistically significant improvement in all measured areas 1 month post successful RFA as compared with pre ablation. Post ablation, the greatest score improvement was in physical functioning. Older children (>12 years) showed the greatest benefit, but gender and type of SVT did not influence outcome.

Conclusions RFA therapy is useful in improving QoL and perceptions in children with recurrent SVT.
