Myocardial Viability Imaging
The concept of hibernating myocardium originated from observations in the 1970s that the myocardial dysfunction seen in patients with chronic coronary artery disease (CAD) was not always permanent (1). The fact that revascularization with coronary artery bypass grafting (CABG) could result in the recovery of contractile function in previously akinetic segments led to the development of numerous...
متن کاملMR imaging of myocardial perfusion and viability.
CMR is a rapidly developing new modality with applications in clinical cardiology for detection and assessment of myocardial ischemia and viability. CMR perfusion results for the detection of ischemia in comparison with stress echocardiography and scintigraphic techniques are reasonable, but all the studies reported to date have been conduced in selected patients. Larger studies in patient popu...
متن کاملMyocardial viability assessment using nuclear imaging.
Myocardial assessment continues to be an issue in patients with coronary artery disease and left ventricular dysfunction. Nuclear imaging has long played an important role in this field. In particular, PET imaging using 18F-fluorodeoxyglucose is regarded as the metabolic gold standard of tissue viability, which has been supported by a wide clinical experience. Viability assessment using SPECT t...
متن کاملHybrid Imaging in the Assessment of Myocardial Ischemia and Viability
Myocardial ischemia results from a reduction in blood flow as a consequence of a coronary stenosis, which produces ischemia in the myocardial territories irrigated by the stenotic artery. Myocardial viability is a concept that derived from several studies in which it was observed that, even if revascularization occurred, an irreversible left ventricular contractile dysfunction remained. The ter...
متن کاملNoninvasive imaging of myocardial viability: current techniques and future developments.
Complete knowledge of myocardial structure, metabolism, and function is crucial to understanding the response of the heart to injury such as ischemia. Increasingly, this type of knowledge is required at multiple levels, from that of the isolated myocyte to the functioning organism, to provide basic scientists and clinical investigators a common framework for translation of findings and informat...
