The efficacy and safety of using amplatzer for transcatheter closure of atrial septal defect in small children with less than 10 kg

摘要

BACKGROUNDAtrial septal defect (ASD) accounts for about 10% of congenital heart diseases (CHDs). Self-closure of these defects in patients with defects less than 8 mm has been reported in several studies. In children, transcatheter closure of the ASD is suggested for asymptomatic patients older than two years and with weight > 15 kg. The purpose of this study was to show that transcatheter closure of ASD in small children with body weight less than 10 kg is an effective and safe method.
