Three dimensional evaluation of the aortic annulus using multislice computer tomography: are manufacturer's guidelines for sizing for percutaneous aortic valve replacement helpful?
Why the study?
To evaluate the effects of applying current sizing guidelines to different MSCT aortic annulus measurements on Corevalve size selection.
Does the choice of MSCT aortic annulus measurement method affect Corevalve size selection and eligibility in patients referred for percutaneous valve replacement?
Population
75 patients referred for percutaneous valve replacement
Comparison
Corevalve sizing across different MSCT annulus measurements

P
Population
75 patients referred for percutaneous valve replacement
I
Intervention
Application of current sizing guidelines to different multislice computer tomography (MSCT) aortic annulus measurements (Dmin, Dmax, Dmean, Dcirc, DCSA)
O
Outcome
Corevalve (CRS) size selection and eligibilitysurrogate
Eligibility and size selection for percutaneous aortic valve replacement vary substantially depending on the MSCT sizing criterion used, highlighting the need for guidelines to account for the oval shape of the aortic annulus.
