May improve LV wall motion measurement consistency; leaves open clinical validation and outcome impact.
A newly developed algorithm for the centerline LV wall motion model successfully prevents measurement chords from crossing, achieving high convergence stability.
Land et al. (2002) studied Left ventricular wall motion analysis (n=110). New centerline LV wall motion model algorithm was evaluated on Variation in overall chord lengths between iterations. A new centerline LV wall motion model algorithm achieved a variation of less than 1% in overall chord lengths in 99.1% of the 110 ventricular contour pairs examined.
