Figure 6 Pressure-Strain Relationship for Biomechanical Compliance

Pressure-strain relationship for biomechanical compliance of the left ventricular anterior wall. Circumferential strain (E₁₁) is shown in (A) and longitudinal strain (E₂₂) in (B). For both directions, the infarction control group exhibited the least compliance, while the polyester urethane urea patch group was significantly more compliant, being between infarcted and normal or equivalent to normal tissue.
