[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 ...

On myocardial perfusion, metabolism, and viability
Journal of Nuclear Cardiology, 1998The majority of the examinations performed in nuclear cardiology laboratories are perfusion studies obtained for the evaluation of coronary disease. The number of studies performed for the assessment of myocardial viability is growing and will continue to grow as more sophisticated techniques for revascularization are introduced and the number of ...

Evaluation of Myocardial Viability by MRI
Herz, 2000Distinguishing between viable and non-viable myocardium is an important clinical issue. Several magnetic resonance (MR) techniques to address this issue have been proposed. Spectroscopy of phosphorus-31 and hydrogen-1 from creatine as well as imaging of sodium-23 and potassium-39 reflect information related to cellular metabolism.

Echocardiography for the assessment of myocardial viability
Journal of the American Society of Echocardiography, 1997The identification of viable myocardium in the setting of acute myocardial infarction or chronic coronary artery disease with reduced left ventricular function has important prognostic and therapeutic implications. Many noninvasive methods have been used to assess viability, and recently, dobutamine stress echocardiography has been studied for this ...

[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.

Myocardial Viability: It is Still Alive
Seminars in Nuclear Medicine, 2014Heart failure presents a significant problem in industrialized countries, with a high prevalence, morbidity, and mortality, where it is most frequently caused by coronary artery disease. Revascularization in patients with symptomatic heart failure has been associated with improved cardiovascular outcomes.

Myocardial Viability: Nuclear Assessment
Echocardiography, 2005There are an estimated 5 million patients with congestive heart failure (CHF) in the United States. The long‐term outcome in these patients is poor with a 5‐year mortality of 70%. There is evidence suggesting that revascularization in patients with viable myocardium can result in reduced event rate in these patients.

Assessment of myocardial viability by PET
Current Opinion in Cardiology, 2019Viability assessment has a key role in the management of patients with ischemic heart disease. Positron emission tomography (PET) is a unique modality that evaluates myocardial viability via assessing the tissues metabolic and perfusion properties. The mainstay of metabolic imaging relies on glucose metabolism using fluorodeoxyglucose, a radiolabeled ...

MRI for the Assessment of Myocardial Viability
Magnetic Resonance Imaging Clinics of North America, 2007Accurate distinction between viable and infarcted myocardium is important for assessment of patients who have cardiac dysfunction. Through the technique of delayed-enhancement MRI (DE-MRI), viable and infarcted myocardium can be simultaneously identified in a manner that closely correlates with histopathology findings. This article provides an overview
