Two-dimensional analysis may underestimate device-related stresses; leaves open need for three-dimensional validation before clinical adoption.
Two-dimensional principal stress analysis can significantly underestimate peak turbulent stresses in complex three-dimensional flows of cardiac prostheses compared to three-dimensional analysis.
