Pulse-Cancellation Echocardiography for Clinical Evaluation of Myocardial Scar Burden
Current Cardiology Reports, 2021 Purpose of Review: Echocardiography has been completely abandoned as far as myocardial tissue characterization is concerned, but recently, the possibility to detect scarred myocardial tissue has been revived.

Nerve fibers in human myocardial scars
Human Pathology, 1991The relationships between ischemic heart disease, myocardial scars, ventricular nerve fibers, and ventricular arrhythmias have not been established despite considerable evidence suggesting important correlations. We recently described the reactions of nerve fibers in necrotic, healing, and healed rat myocardium.

Automatically computed ECG algorithm for the quantification of myocardial scar and the prediction of mortality [PDF]
Clinical Research in Cardiology, 2018 BACKGROUND Myocardial scar is associated with adverse cardiac outcomes. The Selvester QRS-score was developed to estimate myocardial scar from the 12-lead ECG, but its manual calculation is difficult.

Physiological Implications of Myocardial Scar Structure
Comprehensive Physiology, 2015ABSTRACT Once myocardium dies during a heart attack, it is replaced by scar tissue over the course of several weeks. The size, location, composition, structure, and mechanical properties of the healing scar are all critical determinants of the fate of patients who survive the initial infarction.

CT myocardial perfusion and scar imaging
2022Abstract Stress myocardial perfusion imaging by CT allows for identification of inducible myocardial ischaemia and haemodynamically significant coronary artery disease. Dynamic perfusion imaging allows for quantitative perfusion analyses but requires high-end CT technology. CT can identify acute and chronic myocardial injury based on low

The scar neovasculature after myocardial infarction in rats
American Journal of Physiology-Heart and Circulatory Physiology, 2005A series of novel techniques, adapted from the field of tumor biology, were developed to quantify vascular structure and function and to explore the role of ANG II receptor AT1 in cardiac remodeling after myocardial infarction (MI). We examined the scar neovasculature at 1–4 wk post-MI in Sprague-Dawley rats with a view toward its ability to deliver ...

TENASCIN AND FIBRONECTIN EXPRESSION IN HEALING HUMAN MYOCARDIAL SCARS
The Journal of Pathology, 1996Fibronectin and tenascin are matrix proteins known to be present in early experimental wound healing. As only limited data are available regarding early matrix changes in human myocardial infarction, the presence of tenascin and fibronectin was studied in human myocardial infarctions of different post-infarction times (6 h to 17 years), using ...

MR Imaging of Myocardial Scar, with Electrophysiology Applications
PET Clinics, 2011This article reviews the increasing role of cardiac MR imaging to quantitatively assess myocardial scar in the context of clinical cardiac electrophysiology. After a quick overview of the biologic aspects of myocardial scar, two imaging techniques currently used to routinely image scar in cardiac electrophysiology contexts are described, MR imaging and

Evaluation of myocardial scarring and perfusion
2019Myocardial CT perfusion (CTP) imaging is increasingly being used in routine clinical practice as a technique for detecting myocardial ischaemia. CTP offers the advantage of combining anatomical and functional evaluation of coronary stenosis in the same examination and enhances the accuracy of CTA in both patients with suspected and known CAD.

Signal intensity of myocardial scars at delayed-enhanced mri
Acta Radiologica, 2009Background: Traditionally, unrecognized myocardial infarction (UMI) is defined as the appearance, in a non-acute setting, of a new diagnostic Q wave. In the recent past, delayed-enhanced magnetic resonance imaging (DE-MRI) has provided a new imaging method for evaluating myocardial viability and to detect myocardial scars. Purpose: To
