The complex architecture of oblique fiber orientation in the left ventricular wall is important for integrating myocyte shortening into extensive wall thickening and rapid wall thinning.
Magnetic resonance tissue tagging is a powerful new technique for the non-invasive characterization of myocardial deformation. The fibers in the intact left ventricular wall change from an oblique orientation at the epicardium, to a circumferential orientation at the midwall, to a reverse oblique direction at the endocardium 1,2. The importance of this complex architecture for integrating shortening of individual myocytes into extensive wall thickening and re-lengthening into rapid wall thinning, is addressed below.
Shapiro et al. (Sat,) conducted a review in Left ventricular wall deformation. Oblique fiber orientation was evaluated. The complex architecture of oblique fiber orientation in the left ventricular wall is important for integrating myocyte shortening into extensive wall thickening and rapid wall thinning.
