Healthy and Scar Myocardial Tissue Classification in DE-MRI
2013We propose an automatic technique to segment scar and classify the myocardial tissue of the left ventricle from Delay Enhancement (DE) MRI. The method uses multiple region growing with two types of regions and automatic seed initialization. The region growing criteria is based on intensity distance and the seed initialization is based on a thresholding

Nuclear DNA of myocardial cells in the periphery of infarctions and scars
Virchows Archiv B Cell Pathology, 1977In 20 hearts the enlargement of muscle fibers and the increase in nuclear DNA is studied in the periphery of fresh and healed infarctions. The data of attack is verified by ECG records in most cases, five had passed undiagnosed. Selective cytophotometry is performed by measuring the largest nucleus in each of 50 fields of comparable density.

ISMRM Annual Meeting
There remains no standard method for quantification of myocardial infarction (MI) from LGE images. Current methods lack reproducibility as they rely on manual or threshold-based scar segmentation. Notably, these methods only quantify scar volume/percentage but ignore the impact of myocardial LGE distribution pattern.

Myocardial scar as arrhythmia risk in patients with hypertrophic cardiomyopathy
Current Opinion in Cardiology, 2010To provide an overview of the potential use of contrast-enhanced MRI as tool for further risk stratification in patients with hypertrophic cardiomyopathy (HCM).The presence of scar measured by contrast-enhanced MRI has been shown to predict poor prognosis in several models of cardiomyopathy, including ischemic and nonischemic dilated cardiomyopathy ...

The effect of early exercise on myocardial infarct scar formation
American Heart Journal, 1983The purpose of this study was to determine if exercise undertaken during the phase of incomplete healing after myocardial infarction influences scar formation. Eighteen ether-anesthetized rats underwent coronary artery occlusion (CAO) and were paired by matching ECG infarct size as assessed by QRS morphology. One member of each pair was randomized to a

Photoacoustic Tracing of Postinfarction Myocardial Scarring by Collagen Hybridization
ACS SensorsMyocardial infarction (MI) leads to fibrotic scarring, which impairs cardiac function and necessitates accurate assessment for prognosis and therapy evaluation. Unfortunately, current imaging modalities lack direct specificity for fibrosis. Here, we report a photoacoustic (PA) imaging strategy based on an indocyanine green-loaded albumin nanoparticle ...

Impact of ischemia and scar on therapeutic benefit of myocardial revascularization
Herz, 2013The question of how to optimally manage coronary artery disease (CAD) has been a challenge for the cardiology community. The results of early, large randomized clinical trials (RCTs) comparing strategies of medical therapy alone versus revascularization plus medical therapy in patients with stable CAD suggested a survival advantage for a ...
