The goal of the present prospective study was to assess health-related quality of life in children and adolescents with CHD before and after cardiac catheter treatment.

The study enrolled 96 children/adolescents with CHD from the north-east of China who underwent cardiac catheter intervention treatment between March, 2013 and January, 2014. The health-related quality of life at 24 hours before treatment, 1 month after treatment, and 6 months after treatment was evaluated using Pediatric Quality of Life Inventory Measurement Models 4.0 (PedsQLTM 4.0) generic core scales, and the scores were further compared.

Before treatment, each HRQOL domain score and the total score were obviously decreased than the post-treatment scores (1 month and 6 months). The total score and the scores in physical functioning and psychological functioning components were further increased 6 months after treatment than the scores 1 month after treatment.

The present study suggests that cardiac catheter interventional treatment improves the life quality of children or adolescents with CHD as time increases after the intervention.
