We propose an automatic pipeline to generate digital twin aortae from 2D+time MRI slices. First, a statistical shape model is fitted to the segmentation of 2D slices over time and then local refinements are applied to closely match dynamics over time. The approach is exemplified on a dataset of 10 aortic stenosis patients on which we quantify the impact of the number of available slices on the reconstructed anatomy.
