CAPFs in our cases, which developed in their adulthood, anatomically correspond with the vasa vasorum of the proximal of the great arteries. The dual origin multiple plexus-like CAPFs might develop from the vasa vasorum of the proximal portion of the great arteries with age. The antegrade approach would be effective because even dual origin multiple plexus-like CAFs converged and drained to a single major exit of the pulmonary trunk. Catheter occlusion could be feasible and safe for dual origin multiple plexus-like CAPFs.
