Does noninvasive CMR iSvO2 predict mortality and heart failure hospitalization in patients with heart failure?
CMR iSvO2 derived from T2 maps provides an accurate, noninvasive estimation of invasive SvO2 and independently predicts mortality and heart failure hospitalization.
The CMR iSvO2, measured from simple T2 maps of left and right ventricular blood pool, allows accurate estimation of the invasive SvO2. In a real-world heart failure registry, iSvO2 is an independent predictor of mortality and heart failure hospitalization.
