Journal of Cardiovascular Development and Disease, 2022 Left bundle branch block (LBBB) is associated with specific septal-to-lateral wall activation patterns which are strongly influenced by the intrinsic left ventricular (LV) contractility and myocardial scar localization. The objective of this study was to

Quantification of Resting Myocardial Blood Flow Using Rubidum82 Positron Emission Tomography in Regions with MRI-Confirmed Myocardial Scar. [PDF]
Ann Nucl Cardiol, 2022 Background: Resting myocardial blood flow (rMBF) within regions of myocardial scar as measured by positron emission tomography (PET) has not yet been assessed with the radiotracer Rubidium(82) (Rb(82)) or correlated with scar thickness.

Macrophages produce collagen for myocardial scar formation [PDF]
Nature Reviews Cardiology, 2020 Macrophages directly contribute collagen to scar formation as part of heart regeneration in zebrafish and heart repair in mice; this finding develops the current paradigm of collagen deposition for scar formation being generated exclusively via macrophage-mediated activation of cardiac fibroblasts to myofibroblasts.

Multisite pacing and myocardial scars: a computational study
Computer Methods in Biomechanics and Biomedical Engineering, 2020 Cardiac resynchronization therapy (CRT) is a frequently effective treatment modality for dyssynchronous heart failure, however, 30% of patients do not respond, usually due to suboptimal activation of the left ventricle (LV). Multisite pacing (MSP) may increase the response rate, but its effect in the presence of myocardial scars is not fully understood.

Measuring Myocardial Scar by CMR
JACC: Cardiovascular Imaging, 2011 Late gadolinium enhancement (LGE) using cardiac magnetic resonance (CMR) has emerged as the gold-standard technique for imaging of myocardial scar. The basic principle is inversion-recovery imaging after a 5- to 10-min delay following intravenous administration of gadolinium contrast ([1][1 ...

Journal of Cardiovascular Magnetic Resonance, 2011 Background The segmental relationship between cardiovascular magnetic resonance (CMR) peak circumferential strain (Ecc) and myocardial scar has not been well characterized in Duchenne muscular dystrophy (DMD), and it is unknown whether echocardiography ...

On the detection of myocardial scar based on ECG/VCG analysis
, 2013 In this paper, we address the problem of detecting the presence of myocardial scar from standard ECG/VCG recordings, giving effort to develop a screening system for the early detection of scar in the point-of-care.

Transmural “Scar-to-Scar” Reentrant Ventricular Tachycardia [PDF]
, 2013 We describe a scar-related reentrant ventricular tachycardia circuit with a proximal segment in an endocardial basal septal scar and an exit in a region of slow conduction in a non-overlapping region of epicardial basal lateral scar.

Frontiers in Physiology, 2016 Myocardial electrical impedance is a biophysical property of the heart that is influenced by the intrinsic structural characteristics of the tissue. Therefore, the structural derangements elicited in a chronic myocardial infarction should cause specific ...
