Patients with unicuspid or bicuspidAoVs are also at increased risk of aortic dissection. Interestingly,atherosclerosis is not considered an independentrisk factor for aortic dissection but does increase the riskof free rupture following dissection (28).Patients with acute aortic dissection typically describesudden severe chest and/or back pain. At the onset, thepain is most severe, sometimes excruciating, with littleor no change in the intensity but sometimes with migratinglocation or in association with syncope.
