Computed tomography (1A), frontal thoracic aortography (1B), and lateral
thoracic aortography (1C) showed an isolated long-segment mid-thoracic
aortic coarctation. A dumbbell morphology (1D) was visualized before
full expansion of an Advanta V12 Large Diameter Stent (AVLDS). After
implantation, repeated thoracic aortography (1E) showed full AVLDS
dilatation. Follow-up thoracic aortography (1F and 1G) and computed
tomography (1H) showed in situ AVLDS anchoring to the aortic wall
effectively and covering the full length of the coarctation
sufficiently.

Computed tomography (Figure 1 A ) and angiography (Figure 1 B and 1C) identified the cause to be MAS, manifesting as an isolated long-segment mid-thoracic coarctation. AVLDS to treat this lesion (Figure 1 D and 1E). AVLDS was distended gradationally by increasing the balloon pressure from a nominal pressure of 8 atm to a burst pressure of 12 atm. After SI, the lesion was dilated from 6.38-6.45 mm to 10.57-1 0.68 mm (Figure 1 F and 1G). Follow-up computed tomography showed AVLDS in situ covering the full length of the mid-thoracic coarctation (Figure 1 H).
