The procedure was carried out in the cathlab, under general anesthesia and with both fluoroscopy and transesophageal echocardiography guidance. Basal physical examinations and echocardiograms were performed prior to the procedure and at 30 days, 6, and 12 months of follow\u2010up. Survival free of symptom was estimated by Kaplan\u2013Meier. <jats:styled-content>Results:<\/jats:styled-content> The mean age, weight, height, body mass index, and corporal surface was: 5.35 \u00b1 2.11 years, 23.07 \u00b1 9.43 kg, 110.55 \u00b1 17.6 cm, 16.77 \u00b1 2.42 kg\/m<jats:sup>2<\/jats:sup>, and 1.24 \u00b1 2.44 m<jats:sup>2<\/jats:sup>. The prevalence of septal aneurysm was 3.7% and all patients presented single <jats:italic>secundum<\/jats:italic> ASD. The mean stretched diameter by fluoroscopy and transesophageal echocardiography were 17.18 \u00b1 6.75 mm and 16.77 \u00b1 5.99 mm, and the prostheses sizes were 18.83 \u00b1 6.98 mm, ranging from 10 to 30 mm. The systolic and diastolic pulmonary pressures were 25.26 \u00b1 5.97 mm Hg and 13.38 \u00b1 3.40 mm Hg, respectively. The procedure time was 82.92 \u00b1 29.14 min and the hospital stay was 2.20 \u00b1 0.26 days. Clinical and echocardiography follow\u2010ups were performed within 11.59 \u00b1 4.42 months and all devices were in the correct position with no residual shunt. Right ventricular diameter decreased from 19.38 \u00b1 5.23mm to 11.38 \u00b1 11.92 (<jats:italic>P<\/jats:italic> 0.001). No major complications or deaths occurred; two patients had a hematoma at the vascular access. <jats:styled-content>Conclusion:<\/jats:styled-content> Secundum atrial septal defect closure can be safely and successfully performed with the Amplatzer septal occluder in children younger than 10 years old. \u00a9 2008 Wiley\u2010Liss,
