Objectives: We studied immediate and midterm results of transcatheter closure of atrial septal defects (ASDs) using the Amplatzer septal device closure. Methods: The study included one hundred and thirty-seven patients (31 men, 106 women; mean age 8 ± 7.3 years; range 1–65 years) who underwent transcatheter closure of secundum ASD between October 2014 and October 2016 in our center. All the patients were evaluated by transthoracic echocardiography before and during the procedure and in adult patients; transesophageal echocardiography was performed before the procedure. Closure of ASDs was performed under general anesthesia with transthoracic echocardiographic guidance. Follow-up controls were done on the day after procedure, 1 week, 1, 3, 6, and 12 months, and annually thereafter. The median follow-up periods of ASD was 15 months. Results: The mean ASD and device size were 13.5 ± 2.3 and 14.3 ± 3.2 mm, respectively. The mean procedural and fluoroscopy times were 21.3 ± 4.7 and 5.1 ± 1.9 min. Immediate complications such as mortality, bleeding, fatal arrhythmia, and device embolization did not occur in any patient during and after the procedure. Cardiac arrhythmias were seen in 4 patients during the 1st month after the procedure. Late device embolization did not occur during the follow-up. No residual shunts were seen after the procedure. Transient ischemic attack was seen in one patient during the procedure and in one patient 2 days after the procedure without long-term complication. Conclusion: Transcatheter closure of ASDs using the Amplatzer devices is an efficacious and safe therapeutic option.
