Hypoplastic Aortic Arch

Patient History

The patient is a 32 year old male with a hypoplastic aortic arch. At age 4 years, the ascending aorta was enlarged for supravalvular aortic stenosis repair. At age fifteen, a 20 mm woven dacron graft was inserted from the ascending to descending aorta for hypoplastic aortic arch. The graft was replaced 9 years later. He was recently diagnosed with sever aortic insuffuciency secondary to homograft failure, moderate mitral insufficiency, modertae tricuspid insufficiency, and status post homograft replacement.

Shaded Surface Displays

Shaded Surface Displays (SSDs) are often useful to surgeons to gain preoperative knowledge about spatial relationships between cardiac and vascular structures.
