Symptomatic patients or patients at good risk should undergo surgical repair earlier than in the case of abdominal aortic aneurysm without dissection (AAA). Dissection in addition to an AAA will further increase the weakness of the aortic wall and the possibility of aortic rupture will become higher.

All CEP, Magna and Magna Ease valves seemed to be similarly useful in Japanese elderly patients with severe AS. Our data did not clearly support the superiority of one valve over another. A longer follow-up period might be necessary to compare the durability and hemodynamic performance of these valves with more certainty.
