Figure 1 (A) Color Doppler mapping shows a ductal shunt jet (arrows) from the ductal aneurysm to the main pulmonary artery in a high parasternal short-axis view. The "triple star sign" consists of the ascending aorta, the main pulmonary artery and the ductal aneurysm. (B) The "rabbit ear sign" consists of the transverse arch and descending aorta as the right-side ear, and the elongated ductal bump, with terminal dilatation, as the left-side ear, in a modified high parasternal short-axis view. Arch = transverse arch of aorta; AsAO = ascending aorta; DAO = descending aorta; MPA = main pulmonary artery.

Figure 2 (A) The three-dimensional reconstructed magnetic resonance angiography shows a large ductal aneurysm three days after birth. (B) The follow-up three-dimensional reconstructed magnetic resonance angiography reveals a marked decrease in the size of the ductal aneurysm (arrow) at one month. DAA = ductus arteriosus aneurysm.
