Catheter closure of atrial septal defect in anatomically corrected malposition with left juxtaposition of the atrial appendages using intracardiac echocardiography.

Anatomically corrected malposition is characterized by abnormally related great vessels and atrioventricular and ventriculoarterial concordance. It is often associated with juxtaposition of the atrial appendages where the plane of the atrial septum is abnormally oriented. We describe the device closure of an atrial septal defect in a patient with such a lesion under intracardiac echocardiography guidance.
