Results 30 ASD Ⅱ patients (20 females) underwent transcatheter closure at a median age of 18.4 years (5-55 years). Both the stretched diameters of ASDs and the sizes of the devices were from 18 to 34?mm (25±7?mm). The successful placement rate was 100%. The rest shunt documented by color Doppler, was immediately after implantation in 40% of patients, in 9.9% after 24 hours, and in 3.3% trace at 3 months. No serious complications were observed. There was improvement in symptoms and in cardiac size. Septal motion abnormalities normalized in all patients after 3 months follow-up.Conclusion The Amplatzer septal occluder is a safe and effective device for transcatheter closure of ASD Ⅱ. Long-term follow-up is still required before widespread clinical use can be recommended.展开更多

The most common approach of the procedure is via femoral vein. However, when the inferior vein cava is interrupted or obstructed, it is unfeasible to carry out the procedure via femoral vein. So an alternative approach such as internal jugular vein or subclavian vein needs to be considered.展开更多
