Abstract
Background/Objectives: Quantitative patent ductus arteriosus (PDA) geometry in congenital heart disease (CHD), particularly in relation to aortic arch abnormalities, is incompletely characterized. We evaluated CT-derived PDA geometry.
Methods
This retrospective exploratory single-center study included 168 infants with CHD and a PDA on cardiovascular CT. Aortic-end, pulmonary-end, and mid-duct diameters and ductal length were measured. The Ductal Length-to-Diameter Index (LDI), selected during exploratory analysis, was defined as ductal length divided by the mean end diameter. Seventy-three patients had CT-documented aortic arch obstruction or hypoplasia.
