OBJECTIVES: This study sought to analyze the safety, efficacy, and follow-up results of percutaneous closure of secundum atrial septal defect (ASD) in young children. BACKGROUND: Results of ASD transcatheter closure in adults are widely reported but there are no large published series concerning young children. METHODS: Between December 1996 and February 2002, 48 of 553 patients percutaneously treated at our institution were children age ≤5 years. Indications for closure were: elective closure in 32 patients; frequent respiratory infections in 8; failure to thrive in 2; liver transplantation in 5; and a fenestrated Fontan in 1. The procedure was carried out under general anesthesia with fluoroscopy and transesophageal control. Two different devices were used: 1) the CardioSEAL/StarFLEX (CS/SF) and 2) the Amplatzer septal occluder (ASO). Basal physical examinations and echocardiograms were performed prior to the procedure and at follow-ups (1, 6, and 12 months, and yearly thereafter). RESULTS: The mean age at closure was 3.6 ± 1.3 years. A CS/SF was used in 10 subjects; an ASO was used in 38 patients. No deaths or immediate major complications occurred. The total occlusion rate was 87% at procedure, rising to 94% at discharge. The mean follow-up was 18 ± 14 months. No midterm major or minor complications occurred. The occlusion rate rose to 100% at 12 months of follow-up. Symptomatic patients improved significantly. CONCLUSIONS: In the current era and in experienced hands, ASD closure can be performed safely and successfully, even in very young children. © 2003 by the American College of Cardiology Foundation.
