Abstract：Objective To investigate the safety,feasibility and effectiveness of simple ultrasound-guided percutaneous atrial septal defect(ASD)closure in children.Methods A total of 180 children who underwent interventional closure after strict cardiac ultrasound assessment were included.They were divided into the X-ray group(120 cases)and the ultrasound group(60 cases)based on the guiding method.The preoperative clinical characteristics,surgical indicators and postoperative outcomes were compared between the two groups.Results Compared with the X-ray group,the proportion of preoperative pulmonary valve insufficiency and mitral valve insufficiency were lower in the ultrasound group,and the cardiothoracic ratio was smaller(P<0.05).All surgeries in both groups were successfully completed.Compared with the X-ray group,the defect diameter and the diameter of the used occluder were smaller in the ultrasound group,and the distances from the opposite side edge and the inferior vena cava entrance were longer in the ultrasound group(P<0.05).Compared with the X-ray group,the postoperative hospital stay in the ultrasound group was shorter,the difference in white blood cell levels before and after surgery was greater,the postoperative right atrial diameter and postoperative right ventricular diameter were larger,the postoperative reduction rate of right ventricular dirameter and the incidence of postoperative arrhythmia was lower(P<0.05).There was no statistically significant difference in the incidence of occluder endothelialization within 6 months after surgery between the two groups.Conclusion Simple ultrasound-guided ASD closure is safe and effective.The surgical success rate is not inferior to that of X-ray-guided ASD closure,and the postoperative hospital stay is shorter.
