the blood ow toward the arterial duct. This resulted in maintaining high intraluminal pressure within the duct, and the blood owing through it will have low arterial PO2. The availability of both factors leads to a situation mimicking intrauterine status. This makes us hypothesize that the arterial duct, even without stenting, may still remain patent following pulmo- nary artery branch banding. We understand that this hypothesis needs to be discussed and tested further. However, it is worth to be thought about, as it might
simplify the hybrid procedure and eliminate stent-re- lated complications. We would be interested to hear the thoughts of the respective readers.
