This diagram depicts the variations in PDA configuration based on the Krichenko angiographic classification:
- type A: conical ductus with prominent aortic ampulla and constriction near the pulmonary artery end
- type B: window-like (wide and very short) ductus
- type C: tubular ductus without constrictions
- type D: complex ductus with multiple constrictions
- type E: elongated ductus with constriction remote from the anterior edge of the trachea (when viewed on lateral angiography)
