Abstract：Objective: To evaluate the efficacy and safety of transcatheter closure therapy for secundum atrial septal defect (ASD). Methods: 68 patients with secundum ASD (16 male and 52 female), aged 3 to 65 years old, underwent image-guided transcatheter ASD closure in our hospital from Dec. 2009 to Dec. 2014 were collected as objects. All the patients received 12-lead electrocardiogram (ECG), radiography of the chest, and transthoracic echocardiography (TTE) before and at 3 days after the procedure respectively; and all the patients were followed up at 1 month, 3 months, 6 months, 12 months, and 2 years after the procedure respectively. Results: The transcatheter procedure was successfully done in 65 cases of 68 patients. After the procedure, the heart function was significantly improved and no residual shunt discovered by ultrasonography of the heart. Conclusion: Transcatheter closure therapy for ASD is simple, safe and effective, with a high technical success rate.
