Detection of myocardial scar from the VCG using a supervised learning approach [PDF]

open access: yes, 2013
This paper addresses the possibility of detecting presence of scar tissue in the myocardium through the in- vestigation of vectorcardiogram (VCG) characteristics.

Cardiovascular magnetic resonance in the prediction of outcome after cardiac resynchronisation therapy [PDF]

open access: yes, 2011
Contemporary management of patients with heart failure (HF) includes treatment with cardiac resynchronisation therapy (CRT). The benefit of CRT results from several mechanisms, predominantly correction of dyssynchrony.

Fragmented QRS: What Is The Meaning?

open access: yesIndian Pacing and Electrophysiology Journal, 2012
Fragmented QRS (fQRS) is a convenient marker of myocardial scar evaluated by 12-lead electrocardiogram (ECG) recording. fQRS is defined as additional spikes within the QRS complex.

Iron Deposition following Chronic Myocardial Infarction as a Substrate for Cardiac Electrical Anomalies: Initial Findings in a Canine Model [PDF]

open access: yes, 2013
Purpose: Iron deposition has been shown to occur following myocardial infarction (MI). We investigated whether such focal iron deposition within chronic MI lead to electrical anomalies. Methods: Two groups of dogs (ex-vivo (n = 12) and in-vivo (n = 10))

Impact of myocardial scar burden on microvascular resistance reserve in patients with coronary artery disease. [PDF]

open access: yesEur J Nucl Med Mol Imaging
Purpose: The impact of myocardial scar on coronary microcirculation is not well understood. This study aims to evaluate the association between microvascular resistance reserve (MRR) and scar tissue.

Loss of Dictyostelium HSPC300 causes a scar-like phenotype and loss of SCAR protein [PDF]

open access: yes, 2009
Background: SCAR/WAVE proteins couple signalling to actin polymerization, and are thus fundamental to the formation of pseudopods and lamellipods. They are controlled as part of a five-membered complex that includes the tiny HSPC300 protein.

Deep Learning for Multi-Level Detection and Localization of Myocardial Scars Based on Regional Strain Validated on Virtual Patients

open access: yesIEEE Access, 2023
How well the heart is functioning can be quantified through measurements of myocardial deformation via echocardiography. Clinical assessment of cardiac function is generally focused on global indices of relative shortening; however, segmental strain ...

Two-stage Left Atrial Scar Segmentation Based on Multi-scale Attention and Uncertainty Loss [PDF]

open access: yesJisuanji kexue
Atrial Fibrillation (AF) is one of the most common arrhythmias clinically.Accurate segmentation and area assessment of the left atrium and its scar area after myocardial infarction are of great clinical significance for the early diagnosis,treatment ...

A Comparison of Fiber Based Material Laws for Myocardial Scar. [PDF]

open access: yesJ Elast, 2021
The mechanics of most soft tissues in the human body are determined by the organization of their collagen fibers. Predicting how mechanics will change during growth and remodeling of those tissues requires constitutive laws that account for the density and dispersion of collagen fibers. Post-infarction scar in the heart, a mechanically and structurally

Development of an automated updated selvester QRS scoring system using SWT-based QRS fractionation detection and classification [PDF]

open access: yes, 2014
The Selvester score is an effective means for estimating the extent of myocardial scar in a patient from lowcost ECG recordings. Automation of such a system is deemed to help implementing low-cost high-volume screening mechanisms of scar in the primary ...
