Eight-month-old, female diagnosed with patent ductus arteriosus on echocardiography, confirmed on MDCT: (a) Diagrammatic representation of patent ductus; (b) Plain radiograph shows moderate cardiac enlargement, increased pulmonary arterial markings, prominent aortic knuckle and left atrial enlargement (arrow); (c) Short axis Doppler view at the pulmonary arterial level shows the turbulent flow in the region of ductus (arrow). Pulmonary artery is noted medially (triangle). The continuous flow pattern is illustrated in the jet (C1). MDCT coronal (d) and axial; (e) views shows redundant patent ductus arteriosus (open arrows); (d) Size and length of ductus can vary considerably; (f) 3-D MDCT reconstruction demonstrates large ductus (angled arrow) connecting LPA and aorta.
