Why the study?
Does frame geometry play a role in aortic regurgitation after Medtronic CoreValve implantation?
Does frame geometry play a role in aortic regurgitation after Medtronic CoreValve implantation?
Aortic regurgitation after CoreValve implantation is influenced by specific device-host interactions beyond just the calcium load of the aortic root.
Device-host factors beyond calcium warrant attention in CoreValve AR assessment; leaves open frame geometry's causal role pending prospective data.
These findings indicate that AR can be explained by a specific device-host interaction which can only partially be explained by the calcium load of the aortic root.
