Participants were divided into a WeChat group and a leaflet group. Responses to relevant questionnaires and clinical data were recorded and analyzed.

The rate of attrition in the leaflet group was significantly higher than that in the WeChat group. For the postoperative complications, there was no significant difference between the two groups. Perioperative health education for parents of children who undergo transthoracic device closure of VSDs through the WeChat platform can effectively enhance parents' knowledge of care, improve parent satisfaction, which is an effective method to ensure convenient operation and reduce loss to follow-up.
