Data Supplement
Files in this Data Supplement:
- Movie I
-
(AVI) (1.57 MB). Movie of image shown in Figure 3B. Sagittal oblique view of a platinum stent is mounted on a balloon and advanced under real-time MRI guidance to the site of aortic coarctation. Signal from the guidewire channel is colored green.
- Movie II
-
(AVI) (4.60 MB). Movie of image shown in Figure 3C. The platinum stent is deployed by inflating a gadolinium-filled balloon at the site of coarctation.
- Movie III
-
(AVI) (10.2 MB). Movie of images shown in Figure 6. Aortic rupture during real-time MRI using intentionally oversized balloon in an animal model of aortic coarctation. The upper left panel is a sagittal plan, the lower left panel is an axial plane, and the right panel is an interactive 3D volume rendering. Towards the end of the sequence, a focal aortic rupture suddenly appears along the coarctation suture line, with extravasation of blood that appears bright using SSFP MRI.
