There is multi-chamber cardiomegaly.
There is a left-sided aortic arch and descending thoracic aorta.
The Amplatzer atrial septal defect occluding device is barely discernible on the portable seated frontal view.
Reverse portable seated frontal view does not improve the assessment.
There is in addition a migrated metallic embolization coil from multiple previous embolizations of an intrapelvic arteriovenous fistula on history.
This coil is within the descending branch of the right main pulmonary artery.
