Fiber Orientation and Ejection Fraction in the Human Left Ventricle
Open accessAbstract
Fiber orientation and ventricular geometry are incorporated in a mathematical model for ejection fraction of the human left ventricle. The inadequacy of circularly oriented or "constrictor" fibers to explain high ejection fractions of cylindrical, spherical, or ellipsoidal reference ventricles is demonstrated. A class of "helical" fibers is then introduced from which ejection fractions predicted by physiologic amounts of fiber shortening on cylindrical and ellipsoidal reference ventricles are shown to be consistent with those calculated from biplane angio-cardiographic films.

“Overall, these results were consistent with the projections of previous analytical and computational models (3, 25, 36) in that they showed more-homogeneous deformations for HA ventricles.”

In the citing paper
“It has been predicted that EFs should scale as 1 – k2 for CA ventricles (eq. S5) and 1 - k2 q H(α) for HA ventricles (eq. S15) (Fig. 2D) (3), with k being the strain along the fiber axis, q being the apical shortening, and H(α) being the radial shortening based on the fiber’s helical angle (eqs. S5 to S15).”

“It has been hypothesized that HA ventricles would display increased apical shortening (3, 36) and reduced basal displacement (9, 36), owing to differences in myofiber lengths.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
