Coronary fistula to the right atrium: a challenge for the interventional cardiologist.

Congenital coronary fistulas are rare conditions, frequently diagnosed as an incidental finding when a patient is referred for cardiac surgery for another reason. Treatment can be conservative, surgical or more recently through transcatheter closure, depending on local experience and the morphology of the fistula. The authors present the case of a pediatric patient with a large coronary artery fistula from the aorta to the right atrium. Transcatheter closure with a 16 mm Amplatzer(®) vascular plug II and a 6 mm Amplatzer(®) duct occluder was performed, with complete occlusion.
