Background: Atrial septal defect (ASD) is one of the left to right shunt congenital heart diseases. Transcatheter closure of ASD with amplatzer septal occluder (ASO) is an alternative to surgery. Purpose: To describe the experience of transcatheter ASD closure at Dr. Soetomo Regional Public Hospital. Methods: Descriptive study done in children who were diagnosed with isolated ASD. Medical records of transcatheter ASD closure patients were reviewed for five years. The data taken included demographic data, type of echocardiography, procedure and fluoroscopy time, complication, and outcomes. Result: There were 22 medical records of transcatheter ASD closure patients with 16 male patients (16/22) with a median age of 84 months (21-168 months age-range). Transthoracic echocardiography guiding was conducted in 19 patients (19/22), where as transesophageal echocardiography was conducted in 3 patients (3/22). The median ASD size was 9.4 mm (5-24 mm size range). Multiple ASD was found in 3 patients (3/22). Mild tricuspid regurgitation was found in 9 patients (9/22), with a median pressure gradient of 31.6 mmHg (25-37.8 presure range). Median procedure time was 45 minutes (30-190 minutes time range), a median of fluoroscopy time was 8.5 minutes (6-143 minutes time range). Sizing balloon was conducted in 17 patients (17/22). Conclusion: Most of the transcatheter ASD closures are effective and efficient as an alternative to surgery.
