Asynergic myocardial regions in patients with coronary artery disease can be viable. They may have the ability to improve their function after restoring coronary blood flow. Asynergic but viable myocardial regions have a positive inotropic reserve which can be stimulated by catecholamines. Because echocardiography is an established method for evaluating regional left ventricular function, it has the potential to detect the inotropic response of asynergic myocardial regions. In the clinical…

Use of Cyclic Variation of Integrated Backscatter to Assess Contractile Reserve and Myocardial Viability in Chronic Ischemic Left Ventricular Dysfunction
TLDR
Assessment of CVIB from the apical views is a feasible and accurate tool for detecting contractile reserve (CR) and predicting myocardial viability in chronic LV dysfunction.
DETECTION OF VIABLE MYOCARDIUM DURING DOBUTAMINE ECHOCARDIOGRAPHY USING DOPPLER MYOCARDIAL IMAGING IN PATIENTS WITH RECENT MYOCARDIAL INFARCTION
TLDR
PW-DMI allows quantitative assessment of regional systolic and diastolic myocardial velocities and detection of viable myocardium in basal condition and during LDDE.
STRESS ECHOCARDIOGRAPHY Practical Aspects of Performing Stress Echocardiography
TLDR
Experimental and clinical experience suggests that regional wall motion abnormalities may precede both angina and the ECG changes, and stress echocardiography provides additional information on the cardiac mechanical pump function which is an important parameter that helps the clinician to determine prognosis in patients with ischemic heart disease.
Prediction of viability by pulsed-wave Doppler tissue sampling of asynergic myocardium during low-dose dobutamine challenge.
Tissue velocity imaging during dobutamine stimulation for assessment of myocardial viability: segmental analysis in patients after myocardial infarction.
Comparison between dobutamine stress echocardiography and myocardial perfusion scan to detect viable myocardium in patients with coronary artery disease and low ejection fraction.
TLDR
The proportion of segments showing a positive response to dobutamine is significantly lower than those with technetium uptake, which suggests that the cellular mechanisms responsible for a positive inotropic response to adrenergic stimulation required a higher degree of myocyte functional integrity than those responsible for 99mTc-sestamibi uptake.
ASSOCIATION OF VIABILITY OF MYOCARDIUM WITH PARAMETERS OF HEART RATE VARIABILITY IN PATIENTS OF FIRST ANTERIOR MYOCARDIAL INFARCTION
TLDR
HRV could be used as a potential screening tool to detect myocardial viability in patients of MI and influences the time domain as well as frequency domain HRV measures.
Effects of Low‐Dose Dobutamine on Displacement of the Atrioventricular Plane and Assessment of Myocardial Viability in Patients with Acute Myocardial Infarction Treated with Thrombolysis
TLDR
Changes in the amplitude of the AV plane displacement during low‐dose dobutamine stress echocardiography can easily be used to detect myocardial viability at an early stage with late potential spontaneous recovery.
Non-invasive Imaging in Patients With Chronic Total Occlusions of the Coronary Arteries—What Does the Interventionalist Need for Success?
TLDR
There is an increasing number of studies with positive preselectional factors for patients with CTOs, and the aim of this review is to provide a structured overview of the current state of pre-interventional imaging for Ctos.
An introduction to non-invasive cardiac imaging.
TLDR
How the different forms of non-invasive cardiac imaging work, their advantages and disadvantages, when to use each one and finally what developments are likely in the future are explained.
