Histochemical and immunohistochemical analyses of the myocardial scar fallowing acute myocardial infarction [PDF]

Vojnosanitetski Pregled, 2012
Background/Aim. The heart has traditionally been considered as a static organ without capacity of regeneration after trauma. Currently, the more and more often asked question is whether the heart has any intrinsic capacities to regenerate myocytes ...

Localization of Left Ventricular Lead Electrodes in Relation to Myocardial Scar in Patients Undergoing Cardiac Resynchronization Therapy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background The efficacy of cardiac resynchronization therapy may be reduced in the event of pacing within myocardial fibrosis. We aimed to develop a method to determine the anatomical relationships between the left ventricular (LV) lead and myocardial ...

Quantitative evaluation of ischemic myocardial scar tissue by unenhanced T1 mapping using 3.0 Tesla MR scanner [PDF]

Diagnostic and Interventional Radiology, 2014
PURPOSEWe aimed to use a noninvasive method for quantifying T1 values of chronic myocardial infarction scar by cardiac magnetic resonance imaging (MRI), and determine its diagnostic performance.MATERIALS AND METHODSWe performed cardiac MRI on 29 ...

Functional measurements based on feature tracking of cine magnetic resonance images identify left ventricular segments with myocardial scar [PDF]

Cardiovascular Ultrasound, 2009
Background The aim of the study was to perform a feature tracking analysis on cine magnetic resonance (MR) images to elucidate if functional measurements of the motion of the left ventricular wall may detect scar defined with gadolinium enhanced MR ...

Prevalence and Correlates of Myocardial Scar in a US Cohort [PDF]

JAMA, 2015
Myocardial scarring leads to cardiac dysfunction and poor prognosis. The prevalence of and factors associated with unrecognized myocardial infarction and scar have not been previously defined using contemporary methods in a multiethnic US population.To determine prevalence of and factors associated with myocardial scar in middle- and older-aged ...

Phase analysis single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) detects dyssynchrony in myocardial scar and increases specificity of MPI

EJNMMI Research, 2019
Background Myocardial perfusion imaging (MPI) with single-photon emission computed tomography (SPECT) is commonly used to assess patients with cardiovascular disease. However, in certain scenarios, it may have limited specificity in the identification of

Cardiovascular magnetic resonance of scar and ischemia burden early after acute ST elevation and non-ST elevation myocardial infarction [PDF]

Journal of Cardiovascular Magnetic Resonance, 2008
Background The acute coronary syndrome diagnosis includes different classifications of myocardial infarction, which have been shown to differ in their pathology, as well as their early and late prognosis.

Functional implications of myocardial scar structure

American Journal of Physiology-Heart and Circulatory Physiology, 1997
During healing after myocardial infarction, scar collagen content and stiffness do not correlate. We studied regional mechanics and both area fraction and orientation of large collagen fibers 3 wk after coronary ligation in the pig. During passive inflation of isolated, arrested hearts, the scar tissue demonstrated significantly less circumferential ...

Basal septal perforator vein mimicking the “late iodine enhancement” in delayed phase cardiac CT for myocardial scar assessment

Radiology Case Reports, 2019
Delayed-phase cardiac CT is a useful tool for scar detection, based on differences in the volume of distribution of iodine. Although it covers the entire heart, provides uniform, high isotropic spatial resolution, and therefore may be useful for ...

Artificial Intelligence for Contrast-Free MRI: Scar Assessment in Myocardial Infarction Using Deep Learning–Based Virtual Native Enhancement [PDF]

, 2022
Myocardial scars are assessed noninvasively using cardiovascular magnetic resonance late gadolinium enhancement (LGE) as an imaging gold standard.
