Aorta-right atrial tunnel closure using the transcatheter technique: a case of a 3-year-old child.

Aorta-right atrial tunnel is a rare congenital defect. If it is not treated, critical complications can occur. Surgical closure is the treatment of choice, but with increasing experience in transcatheter techniques and the introduction of new occluder devices the percutaneous technique is now a successful modality for closure. In this paper, we report the case of a 3-year-old child with aorta-right atrial tunnel whose defect was closed with the vascular plug 4 device.
