    Midventricular tagged short-axis images from patient 1. Image at top was acquired at end-diastole and shows how basal and midventricular slices were subdivided into anterior (ANT), lateral (LAT), inferior (INF), and septal (SEP) regions. Image at bottom was acquired 45 ms into systole and shows grid overlay used to track tag intersections during systole.

    LV systolic rotations at apex (triangles), midventricle (diamonds), and base (circles) in all 21 patients at baseline. Patients typically exhibited identical rotation at all short-axis levels for the first approximately 20% of systole, at which point they diverged into one of two patterns: either continuation of identical rotation at all levels for the remainder of systole (eg, patient 1) or a divergence of rotation so the apex and base rotated in opposite directions (eg, patient 3).

  • Image Result
    Changes in end-systolic (ES) rotation from baseline (BL) to after PLV (PLV) at base (B), midventricle (M), and apex (A) for each patient (PT) imaged at both times.

    Pooled global and regional end-systolic (ES) rotations at base, midventricle (Mid), and apex for patients at baseline (white bars) and after PLV (striped bars). Apical results are shown for whole slice (ALL), free wall (FRE), and septum (SEP). Results for midventricle and base are shown for whole slice (ALL), anterior wall (ANT), inferior wall (INF), lateral wall (LAT), and septum (SEP). Lateral wall results are absent after PLV because this tissue was removed during surgery. Error bars represent SD. Asterisk indicates P < .05 for difference in rotation at given location between baseline and post-PLV studies; dagger indicates P < .02 for difference in rotation at given location between baseline and post-PLV studies.

  • Image Result
    Systolic torsion in all patients at baseline (line) and after PLV (diamonds). Overall, torsion was unchanged after PLV, although it tended to approach zero at all systolic time points after surgery.
