Neo-sinus flow stasis is influenced by THV expansion and implant depth (CoreValve). The 10% valve under-deployment (oversizing) may facilitate reduced flow stasis in the neo-sinus with minimal increase in pressure gradients. This strategy may be helpful for patient anatomies, which are in-between transcatheter valve sizes.
