Heart and Aorta Type A Aortic Dissection | Page 2

The valve may be replaced or preserved depending on the presence or absence of
valve or annulus involvement.
When the arch of aorta is badly damaged or the psuedolumen is aneurysmal in this
area, the arch should be addressed during surgery. Depending on the extent of
involvement, part (Hemiarch) or entire (Total Arch) arch may be replaced.
