MRI evaluation of myocardial viability
La radiologia medica, 2006Cardiac magnetic resonance imaging (MRI) has become an accurate noninvasive imaging procedure for the study of postischaemic residual cardiac function, thanks to the evolution of MRI machines, postprocessing software and, above all, sequences. After infarction, and in chronic myocardial ischaemia, the degree of contractile dysfunction is one of the ...

[Myocardial viability. The concept of myocardial viability].
Presse medicale (Paris, France : 1983), 1998Certain zones of ischemic, akinetic or severely hypokinetic myocardium are capable of recovering normal contractile function. This is termed myocardial viability and occurs in two different situations: myocardial stunning and myocardial hibernation.This term designates temporary but prolonged impairment of myocardial function resulting from a brief ...

MRI Assessment of Myocardial Viability
Seminars in Ultrasound, CT and MRI, 2006In the presence of coronary artery disease, global left ventricular (LV) systolic function is a critical prognostic indicator. Because of enhanced therapy for myocardial infarction, more patients survive but are left with residual myocardial damage that predisposes them to developing CHF in the future.

Assessment of myocardial viability
Current Opinion in Cardiology, 1997The noninvasive assessment of myocardial viability has proved clinically useful for distinguishing hibernating myocardium from irreversibly injured myocardium in patients with chronic ischemic heart disease or recent myocardial infarction who exhibit marked regional and global left ventricular dysfunction.

Assessment of myocardial viability after myocardial infarction
Journal of Nuclear Cardiology, 2002The data presented above suggest that assessment of myocardial viability after MI, particularly in those patients with severe LV dysfunction, is important for the identification of those with the highest risk, in whom revascularization can be of clinical benefit.

Myocardial Viability Assessment
2015Abstract Heart failure may be a consequence of ischemic or non-ischemic cardiomyopathy. Etiologies for LV systolic dysfunction in ischemic cardiomyopathy include; 1) transmural scar, 2) nontransmural scar, 3) repetitive myocardial stunning, 4) hibernating myocardium, and 5) remodeled myocardium.

[Myocardial viability. Study of viability by myocardial scintigraphy].
Presse medicale (Paris, France : 1983), 1998FUNDAMENTAL PRINCIPLES: Myocardial scintigraphy is a metabolic approach to myocardial viability visualizing the localization, the extent and to some degree the quantity of non-functional yet viable myocardial tissue. Potential for functional recovery cannot be ascertained directly from the scintigram but can be inferred from commonly observed behavior ...

Myocardial viability assessment can be a key factor in determining the direction of care in a patient with coronary artery disease. Many imaging modalities can be utilized for this purpose, including echocardiography, nuclear medicine perfusion scans, and cardiac magnetic resonance imaging.

Noninvasive Assessment of Myocardial Viability
New England Journal of Medicine, 2000Despite advances in medical therapy and improvements in techniques for myocardial revascularization, the prognosis remains poor for patients with ischemic cardiomyopathy, which is characterized by extensive coronary artery disease and diminished global left ventricular function. Five-year rates of survival range from 50 to 60 percent. Survival is worse
