Where would you look to find the remnant of the ductus arterious?

The remnant of the ductus arteriOSus, known as the ligamentum arteriOSum, can be found in the adult heart. It is located between the descending aorta and the left pulmonary artery. This fibrous structure is the result of the closure of the ductus arteriOSus, which connects these two blood vessels during fetal development. In imaging studies, it may be visualized in the mediastinal area near the aortic arch.
