Aortic valve cusp vessel density: Relationship with tissue thickness [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2002 The presence of a microvasculature within aortic cusps implies that tissue oxygen requirements exceed the amount deliverable by diffusion from the tissue surfaces alone. For the design of a successful tissue-engineered valve replacement, the effect of diffusion distance (tissue thickness) on oxygen delivery must be considered.
