Abstract
237 patients after endovascular and surgical closure of secondary isolated ASD were studied. 87 of them (followup 3.1±1.2 years) underwent endovascular closure and 150 patients underwent surgical treatment (follow-up 4.1±2.2 years). After endovascular repair main changes on EchoCG happen during one month after operation, later they become less marked. In the group of surgical repair statistically significant EchoCG changes happen during the year after operation. 85.7% of residual arterio-venous shunts which appeared immediately after occlude implantation close during 3-6 months. In long-term period after open surgical intervention in all cases the size of residual ASD increases by 3-5 mm, there was not observed independent closure of communication between atria. If there is residual shunt at interatrial septum after endovascular ASD closure, reoperation should be conducted at least 6- 12 months after primary repair because during this period complete closure of interatrial communication can occur. After open surgical repair reoperation can be conducted in 6 months because in these patients residual ASD closure does not occur. Endovascular closure of secondary ASD by Amplatzer septal occluder is effective and safe method of repair and can be an alternative to surgical treatment.
