Figure 4From: In-vivo assessment of the morphology and hemodynamic functions of the BioValsalva™ composite valve-conduit graft using cardiac magnetic resonance imaging and computational modelling technology The effective orifice area (EOA). Colour-coded velocity map showing the EOA at peak flow rate above the valves (broken lines) for all subjects, (a) Normal control group and (b) BioValsalva™ patients group. The shapes of the EOA in BioValsalva™ are less regular and smaller.Back to article page
