“…The third finding was that area at risk revealed by CE-SSFP and T2-STIR (using the subset of scans that were of diagnostic value) was similar to the findings in previous studies of culprit artery distribution using myocardial perfusion scintigraphy. 18,19 The results provide evidence that CE-SSFP is an emerging alternative option for edema imaging. It is intriguing that a noninvasive multimodality CMR scan can be used to identify the location of the culprit artery, its perfusion territory, and the amount of residual myocardium amenable to salvage.…”

“…Nordlund et al 17 also set out to compare their results with previous publications on identifying the culprit artery using single photon emission computed tomography. 18,19 The CMR image analyses were performed in a core laboratory using software designed by the same group in the University of Lund, Sweden. The CMR findings from assignment of the culprit artery territory were compared with the reference findings from the invasive coronary angiogram, taking into account the Rentrop collateral grade and infarct assessment using late gadolinium enhancement imaging with CMR.…”

Cardiac magnetic resonance (CMR) imaging in survivors of acute ST-segment-elevation myocardial infarction (STEMI) provides accurate and precise measurements of left ventricular dimensions, and infarct pathologies are uniquely characterized. Acute coronary artery occlusion initiates a wavefront phenomenon of ischemia 1 commencing from the endocardial layer and propagating radially toward the epicardium, and typically, myocardial infarction will supervene unless coronary reperfusion is achieved in a timely manner. The myocardial area at risk is the jeopardized perfusion territory of the culprit artery.

“…It was presented with the remark that there is indeed tremendous variability in the coronary artery blood supply. The variation among patients was later verified in a clinical study that evaluated the correspondence between the 17 segments of the recommended model and the coronary arteries [19]. This great variability calls for using a patient-specific approach towards assessing the coronary arteries and their relation to the myocardium.…”

Abstract-Visually assessing the effect of the coronary artery anatomy on the perfusion of the heart muscle in patients with coronary artery disease remains a challenging task. We explore the feasibility of visualizing this effect on perfusion using a numerical approach. We perform a computational simulation of the way blood is perfused throughout the myocardium purely based on information from a three-dimensional anatomical tomographic scan. The results are subsequently visualized using both three-dimensional visualizations and bull's eye plots, partially inspired by approaches currently common in medical practice. Our approach results in a comprehensive visualization of the coronary anatomy that compares well to visualizations commonly used for other scanning technologies. We demonstrate techniques giving detailed insight in blood supply, coronary territories and feeding coronary arteries of a selected region. We demonstrate the advantages of our approach through visualizations that show information which commonly cannot be directly observed in scanning data, such as a separate visualization of the supply from each coronary artery. We thus show that the results of a computational simulation can be effectively visualized and facilitate visually correlating these results to for example perfusion data.

“…The Anderson-Wilkins acuteness score was developed to enable assessment of acuteness of myocardial ischemia from the 12-lead ECG, and studies have indicated that it may be associated with salvageable myocardium. 93,94 A recent study of 38 patients treated with primary PCI, in which SPECT and CMR imaging were used to determine AAR and final infarct size, showed a moderate correlation between the acuteness score and salvageable myocardium in patients with acute RCA occlusion but not in patients with LAD occlusion. At present, there is no clear consensus regarding the preferred ECG method to estimate AAR.…”

Background:Patients with acute ST-elevation myocardial infarction (STEMI) benefit substantially from emergent coronary reperfusion. The principal mechanism is to open the occluded coronary artery to minimize myocardial injury. Thus the size of the area at risk is a critical determinant of the patient outcome, although other factors, such as reperfusion injury, have major impact on the final infarct size. Acute coronary occlusion almost immediately induces metabolic changes within the myocardium, which can be assessed with both the electrocardiogram (ECG) and cardiac magnetic resonance (CMR) imaging.Methods: The 12-lead ECG is the principal diagnostic method to detect and risk-stratify acute STEMI. However, to achieve a correct diagnosis, it is paramount to compare different ECG parameters with golden standards in imaging, such as CMR. In this review, we discuss aspects of ECG and CMR in the assessment of acute regional ischemic changes in the myocardium using the 17 segment model of the left ventricle presented by American Heart Association (AHA), and their relation to coronary artery anatomy.Results: Using the 17 segment model of AHA, the segments 12 and 16 remain controversial. There is an important overlap in myocardial blood supply at the antero-lateral region between LAD and LCx territories concerning these two segments.Conclusion: No all-encompassing correlation can be found between ECG and CMR findings in acute ischemia with respect to coronary anatomy.
