CTICasesMalpositioned patent ductus arteriosus closure device
Imaging findings
Chest radiograph and CT show a patent ductus arteriosus Amplatzer-type closure device abnormally rotated and located entirely within the left pulmonary artery rather than spanning the ductus lumen, resulting in a persistent left-to-right shunt.
Key takeaways
Patent ductus arteriosus closure devices can migrate or malposition, especially in the setting of a short, broad ductus. Recognition of abnormal device orientation on chest radiographs (such as the broader aortic disc pointing anteriorly) can suggest malposition in the left pulmonary artery.
