Spontaneous closure of a?large atrial septal defect in an infant

摘要

We describe a?patient who, at the age of 6 months (body weight 6.1 kg), was diagnosed with a?large atrial septal defect (with diameter 10–11 mm) that had spontaneously closed in a?1-year period. The timing of transcatheter intervention in children should be considered individually, paying close attention to subsequent echocardiographic data.
