Figure 3: Regression plot showing infarct size and functional parameters. Regression plot of infarct size (a) measured in magnetic resonance imaging with LGE ( axis) compared with histological infarct size in TTC staining ( axis) 24 h after procedure (a—circles, broken line). Infarct size determined by magnetic resonance imaging ( axis) compared with histological infarct size in trichrome staining ( axis) 1 week after procedure (a—rhombi, continuous line). Regression plot of functional parameters (b): fractional area change (FAC) (b—rhombi, continuous line) and fractional shortening (FS) (b—circles, broken line) measured in cine magnetic resonance imaging ( axis) compared with fractional shortening (FS) measured with echocardiography ( axis).
