Catheter interventions in adult patients with congenital heart disease.

Adult patients with congenital heart disease provide a wide variety of challenges for the interventional cardiologist. Procedures can broadly be divided into dilatation or closure. The most common interventions in our own practice are closure of atrial septal defects and patent foramen ovale, although closure of postoperative interatrial communications in Mustard, Senning, or Fontan patients is also possible.
