Acute Infarct Extracellular Volume Mapping to Quantify Myocardial Area at Risk and Chronic Infarct Size on Cardiovascular Magnetic Resonance Imaging.
BACKGROUND Late gadolinium enhancement (LGE) imaging overestimates acute infarct size. The main aim of this study was to investigate whether acute extracellular volume (ECV) maps can reliably quantify myocardial area at risk (AAR) and final infarct size (IS). METHODS AND RESULTS Fifty patients underwent cardiovascular magnetic resonance imaging acutely (24-72 hours) and at convalescence (3 mo...
متن کاملRisk area, infarct size, and the exposure of the wavefront phenomenon of myocardial necrosis in humans.
In the 1970s, Reimer and Jennings performed a multitude of studies in dogs after acute coronary occlusion in which they examined the relation between duration of ischaemia, area at risk, collateral blood flow, and final infarct size. The results of their experiments were summarized by the concept of ‘wavefront phenomenon of myocardial death’. In summary, this concept states that infarct size in...
متن کاملMyocardial Infarct Size and Location
Recent infarcts were compared with the anatomic boundaries of the involved vascular bed in human hearts to determine the amount and location of necrosis in relation to the myocardium at risk. The coronary arteries were injected with BaSo4 in 18 human hearts with 3-16-day-old infarcts. Thin (3-4-mm) slices were cut at 10-15-mm intervals, photographed, x-rayed and used for histologic analysis. In...

متن کاملRelationship Between Myocardial Infarct Size
We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...
