This finding, obtained from ungated SPECT images, is the ratio of the average ventricular size after stress compared with rest. With gated SPECT, however, measurements of the end-diastolic volume (EDV) and end-systolic …

Webb28 juni 2016 · Transient ischemic dilation (TID) of the left ventricle—a ratio of the stress left ventricular (LV) volume to rest LV volume—on myocardial perfusion imaging has … WebbThe purpose of our study was to evaluate the incidence of significant CAD in patients with non-perfusion high-risk markers of ischemia, namely LVEF reduction on stress study and TID, despite a normal SPECT-MPI. In our study, LVEF reduction ≥5% was associated with a lower time until the identification of significant CAD on ICA. WebbMyocardial ischemia is transmurally heterogeneous where the subendocardium is at higher risk. Stenosis induces reduced perfusion pressure, blood flow redistribution away from the subendocardium, and consequent subendocardial vulnerability. We propose that the flow redistribution stems from the highe … guthrie coffee shops
