Transcatheter closure of a large left atrial aneurysm with a right pulmonary artery-to-left atrium connection using the Amplatzer ventricular septal occluder.

A right pulmonary artery-to-left atrium connection is a very rare cyanotic congenital heart defect.

The patient was asymptomatic at last follow-up.
