Figure 1From: Microvascular obstruction following PCI is associated with reperfusion hemorrhage and chronic left ventricular impairmentPaired LV short axis plane CMR images from three patients with acute STEMI obtained shortly after PCI. The left column shows the T2* maps with areas of hemorrhage depicted in red (T2*<20 ms). The right column shows the delayed contrast enhanced images. Enhancing myocardium indicates the extent of infarcted tissue while MVO is demonstrated by subendocardial non-enhancement. In Patient A the LAD was reperfused - the distribution of hemorrhage and MVO within the anterior infarct are similar. In Patient B the RCA was reperfused - Both subendocardial hemorrhage and MVO are present in the inferior wall. In Patient C the OM was involved - There is a partial-thickness lateral wall infarct, but no hemorrhage or MVO.Back to article page
