“…Pereztol-Valdés et al analyzed the correspondence of the 17 LV segments with each of the three major epicardial coronary arteries by myocardial perfusion single-photon emission CT (SPECT) studies during elective percutaneous coronary intervention (PCI) in 50 patients. 95 The study showed that the most specific segments (anterior, anteroseptal, and all apical segments except the inferoseptal) corresponded to the LAD, and the basal anterolateral segment (segment 6) to the LCx, while no segment could be exclusively attributed to the RCA. Eight segments were not attributed to a single coronary artery.…”

“…In the working group paper, the inferior segments (4, 10, and 15) were attributed to the RCA, but in the study by Pereztol-Valdés et al, all patients with LCx disease had involvement of the inferior segments. 95 These observations most probably reflect the great variability in blood supply to the inferior and lateral wall.…”

“…97 They agreed with the observations by Pereztol-Valdés and Ortìz-Pérez that the standard assignment of vascular territories proposed by the AHA 17-segment model is frequently inaccurate. 95,96 However, the division by Cerqueira et al into four walls and 17 segments is easy to understand and probably corresponds to a true anatomic correlation. They also reached promising results with CTA-derived imaging.…”

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.

“…For right coronary artery or left circumflex artery occlusions, no segments were 100% specific. 26 Lund et al demonstrated that delayed enhanced MRI had a higher sensitivity compared to SPECT. 27 DE-MRI presents a sensitivity of 99% in measuring the extent of the infarction scar and 94% in measuring transmural enhancement.…”

For a better assessment of ischemic heart diseases, myocardial viability should be quantified. Current studies underline the importance and the evolution of several techniques and methods used in the evaluation of myocardial viability. Taking into account these considerations, the aim of this manuscript was to present the recent points of view regarding myocardial viability and its clinical significance in patients with ischemic cardiomyopathies and left ventricular dysfunction. On the other hand, the manuscript points out the role of magnetic resonance imaging (MRI), one of the most useful noninvasive imaging techniques, in the assessment of myocardial viability. By comparing the advantages and disadvantages of cardiac MRI, its usefulness can be better appreciated by the clinician. In the following years, it is considered that MRI will be an indispensable imaging tool in the assessment of ischemic heart disease, guiding interventions for revascularization and long-term risk stratification in patients with stable angina or myocardial infarction.

“…However, the AHA noted that the name of the segments should define the location relative to the long axis of the heart and the circumferential location, and individual myocardial segments can be assigned to the three major coronaries by considering their anatomic variabilities (2) . In addition, contrary to the conventional 17‐segment model, several studies have reported, using single‐photon emission computed tomography (SPECT), cardiac magnetic resonance (CMR), and CT, that there are variations in the mapping of segments to left ventricular territories, due to their anatomic variations 3 , 4 , 5 . Therefore, they proposed a revised mapping of segments considering anatomic variations, where some segments were assigned to multiple territories due to per‐patient variability.…”

The purpose of this study was to develop and validate cardiac computed tomography (CT) quantitative analysis software with a patient‐specific, 17‐segment myocardial model that uses electrocardiogram (ECG)‐gated cardiac CT images to differentiate between normal controls and severe aortic stenosis (AS) patients. ECG‐gated cardiac CT images from 35 normal controls and 144 AS patients were semiautomatically segmented to create a patient‐specific, 17‐segment myocardial model. Two experts then manually determined the anterior and posterior interventricular grooves to be boundaries between the 1st and 2nd segments and between the 3rd and 4th segments, respectively, to correct the model. Each segment was automatically identified as follows. The outer angle of two boundaries was divided to differentiate the 1st, 4th, 5th, and 6th segments in the basal plane, whereas the inner angle divided the 2nd and 3rd segments. The segments of the midplane were similarly divided. Segmental area distributions were quantitatively evaluated on the bull's‐eye map on the basis of the morphological boundaries by measuring the area of each segment. Segmental areas of severe AS patients and normal controls were significantly different (t‐test, all p‐values<0.011) in the proposed model because the septal regions of the severe AS patients were smaller than those of normal controls and the difference was enough to divide the two groups. The capabilities of the 2D segmental areas (p<0.011) may be equivalent to those of 3D segmental analysis (all p‐values<0.001) for differentiating the two groups (t‐test, all p‐values<0.001). The proposed method is superior to the conventional 17‐segment in relation to reflection of patient‐specific morphological variation and allows to obtain a more precise mapping between segments and the AHA recommended nomenclature. It can be used to differentiate severer AS patients and normal controls and also helps to understand the left ventricular morphology at a glance.PACS number(s): 87.57.N‐, 87.57.R‐, 87.57.qp
