Case history. A year-old woman was evaluated at the outpatient clinic for shortness of breath and mild substernal heaviness, which increased in severity with moderate tight. The patient had a history of hypertension and coronary artery disease CADand had suffered an acute inferior myocardial infarction six years earlier, for whst she underwent bare-metal stenting in the distal right coronary artery RCA. Suspicion for in-stent restenosis was raised and she was scheduled for a coronary computed tomography angiogram coronary CT angiogram after consultation with a cardiologist.

Figure 1 coronary CT angiogram images revealed right dominant circulation with normal left main coronary artery and non-significant stenosis in the left anterior descending and circumflex arteries territory. Multiplanar images with a special post-processing B46f reconstruction filter showed a patent stent with a what is a placebo effect statistics mild neointimal hyperplasia thin dark line inside the stent lumen Figure 1D.

Figure 2 coronary CT angiogram images demonstrated a subendocardial perfusion defect in the right coronary territory, within the inferior and inferolateral wall of the left ventricle area that appears as a black thick line at the subendocardial region Figures 2B, 2C and 2D. Figure 1. Figure 2. Exercise stress TCm sestamibi SPECT perfusion images demonstrated an inferior and inferolateral transmural infarct with mild ischemia extending from base to apex Arrows in A.

Gated SPECT images showed inferior and inferolateral akinesia with normal left ventricular ejection fraction. The patient was managed medically without symptoms during follow-up evaluations.

Cardiac imaging has become the cornerstone in the workup of patients with suspected or known CAD. The integration of multimodality imaging represents a natural extension of current imaging paradigms for diagnosing CAD, assessing risk and guiding therapeutic decision-making. The latest generation of multidetector CT scanners and the software configuration of section CT scanners provide an appealing alternative for noninvasive luminal assessment in patients with chest pain.

Recently, it has been published that single dual-energy CT provides morphological information on coronary artery luminal integrity and, using the different imaging spectra contained within the same scan, allows the reproducible differentiation of iodine distribution within the myocardium to delineate myocardial perfusion defects, in good correlation with standard techniques. As a result, the integration of a dual-energy CT protocol imaging to evaluate myocardial blood pool during the assessment of coronary anatomy in this patient, may redefine the diagnostic power of DS-MSCT.

However, myocardial blood deficits demonstrated with DS-MSCT cannot differentiate between reversible ischemia and scar with domihant imaging protocols, because coronary CT angiogram is acquired only at rest; this is true for any relative or absolute evaluation of myocardial what is a abusive relationship reserve MPR.

Recently, it has been described an experimental protocol using DS-MSCT to assess both stress and rest myocardial perfusion, in order to identify areas of infarcted or ischemic myocardium. Therefore, to further define the sequelae of coronary atherosclerosis, functional testing for assessment of MPR is ideally performed by nuclear perfusion imaging. Advantages of cardiac SPECT imaging over other cardiovascular imaging modalities cardiovascular magnetic resonance, contrast echocardiography and computed tomography include an extensive literature supporting efficacy rigbt prognostic value, standardized protocols for performing studies, published user guidelines and appropriated criteria, as well as a proven cost effectiveness for diagnosis, management and risk assessment.

Thus, rather than being competitive, MSCT and SPECT imaging should be considered to be complementary for both diagnostic and a prognostic perspective, 9 as it has been shown in this case. The use of the latest generation of multidetector CT scanners and developing novel imaging protocols, combined SPECT and MSCT cardiac imaging, will play a prominent role to detect, quantify, and characterize both clinical and subclinical atherosclerosis, with potential reduction of radiation burden.

We present the case of a year-old woman with chest pain and a history of an inferior myocardial infarction for which she underwent stenting in the right coronary artery. Patient was evaluated by cardiac SPECT and the recently introduced arfery computed tomography DSCT system equipped with two X-ray tubes and two corresponding detectorsin order to detect ischemia associated to stent restenosis.

In this case, DSCT demonstrated a very high diagnostic performance to exclude in-stent restenosis, using a dual-energy protocol, and clearly showed subendocardial distribution of the myocardial perfusion defect, in contrast with the transmural defect seen in the SPECT images. As a result, the integration of a dual-energy CT protocol for the cronary of myocardial blood pool during the assessment of coronary anatomy in this patient, may redefine the diagnostic power of DSCT.

Clinical and angiographic characteristics of patients with combined anterior and inferior ST-segment elevation on the initial electrocardiogram during acute myocardial infarction. In case 1, no additional atherosclerotic coronary disease was found and so, theoretically, an LMCA spasm could have been present. Services on Demand Journal.

Primary coronary angioplasty of an anomalous coronary artery is a challenging and highly complex intervention, particularly in the emergency setting. When this occurs in situations such as physical activity, it leads to an increase of myocardial oxygen demand, producing myocardial ischemia beyond the origin of the fistula; in other cases, signs of heart failure or pulmonary hypertension may be expected.
