The relationship between left ventricular viability and systolic function assessed by circumferential strain in chronically supported LVAD patients. A. The 6 mid LV segments were co-registered between SPECT (left) and echocardiographic (right) imaging in 15 patients. Each segment was categorized as viable (green) or non-viable (red) based upon >55% or ≤55% of peak normalized counts from 99mTc-Sestamibi SPECT imaging, respectively. Circumferential strain from speckle tracking echo was averaged in viable and non-viable segments. B. At reduced LVAD support, circumferential strain was compared between non-viable and viable segments over time and within studies (Baseline: Non viable vs viable p = 0.022; Follow Up: Non viable vs viable p = 0.017).
