Role of magnetic resonance angiography in the diagnosis of major aortopulmonary collateral arteries and partial anomalous pulmonary venous drainage.

Background: Accurate diagnosis of major aortopulmonary collaterals (MAPCAs) and partial anomalous pulmonary venous drainage (PAPVD) in adult patients with congenital heart disease is important but problematic. Three-dimensional contrast-enhanced magnetic resonance angiography (MRA) provides a minimally invasive technique to allow detailed studies in a single breath-hold.

Methods And Results: We assessed the role of contrast-enhanced 3D MRA in 29 consecutive adult patients with a diagnosis of MAPCAs (n=16) or PAPVD (n=13) made by echocardiogram, cardiac catheterization, or surgical inspection.

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.
