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

2019, ARYA Atherosclerosis

BACKGROUND Atrial 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. METHODS Between July 2016 and September 2018, 35 children with body weight less than 10 kg underwent percutaneous closure of ASD using amplatzer. All patients had minimum defect size of 6 mm, pulmonary blood flow (Qp) to systemic blood flow (Qs) ratio above 1.5, right atrial and ventricular dilation, symptoms of delayed growth, and recurrent respiratory infections in their evaluation and had acceptable rims for intervention. Follow-up evaluations were done 1 day, 1 week, 1 month, 6 months, and ye...
