Annular area and perimeter measurements are larger in systole than diastole.

This effect is maintained despite increasing sub-annular calcification.
- class="label">•
Measurements taken from diastolic CT datasets may undersize the aortic annulus.

We recommend systolic data be used for future CT-based sizing algorithms.
