View larger version (17K): [in a new window]   Figure 3 Relationship between LV circumferential end-systolic stress (ESScirc) and LVEF before (closed circles) and after PLV (open triangles). The normal limits (±2 SEE, long dashes) for the control patients are shown for this relation. The figure shows that PLV shifts LVEF-end systolic relations in a parallel to control data.

View larger version (10K): [in a new window]   Figure 4 Relationship between LVSWI and end-diastolic stress before and after PLV. Although there was no improvement in LVSWI, it was performed at significantly lower preload (p = 0.0014), compared to the values before PLV.
