Wild-type Transthyretin Amyloid Deposition in an Ascending Aortic Aneurysm.

Amyloid deposition in aortic tissue is associated with increased stiffness. We report a patient with ascending aortic aneurysm and chronic abdominal aortic dissection who had significant wild-type transthyretin amyloid deposition on surgical pathology. The patient did not have cardiac involvement on further workup.
