Evaluation of bicuspid aortic valve-associated aortopathic changes using third-generation dual-source computed tomography

Figure 1 True axial view obtained by double oblique technique demonstrating type 0 and type 1 bicuspid aortic valve. A: Type 0; B: Type 1. Images acquired during prospective electrocardiography-gated high-pitch acquisition in the best diastolic phase.

Figure 2 Bicuspid aortic valve with type A aortic dissection. A: True axial view demonstrating type 0 bicuspid aortic valve; B and C: Coronal (B) and volume rendered image (C) depicting dilated ascending aorta with type A aortic dissection (shown by blue arrows). Images acquired during prospective electrocardiography-gated high-pitch acquisition in the best diastolic phase.

Figure 3 Bicuspid aortic valve with post ductal coarctation of aorta. A: True axial view demonstrating type 0 bicuspid aortic valve; B and C: Sagittal maximum intensity projection (B) and volume rendered image (C) depicting dilated ascending aorta with post ductal coarctation (shown by arrows). Images acquired during prospective electrocardiography-gated high-pitch acquisition in the best diastolic phase.
