Virtual electrophysiological study in a 3-dimensional cardiac magnetic resonance imaging model of porcine myocardial infarction
2012, Journal of the American College of CardiologyCardiac magnetic resonance imaging: Infarct size is an independent predictor of mortality in patients with coronary artery disease
2011, Magnetic Resonance ImagingCitation Excerpt :Prior MI may serve as a substrate for reentrant tachyarrhythmias which can lead to ventricular fibrillation and sudden cardiac death [22,36,37]. Therefore, the volume of infarct may be a crucial determinant in the development of such arrhythmias related to sudden cardiac death, where the greater the infarct, the larger the substrate for the development of subsequent arrhythmias [20,23,38]. Indeed, Bello et al. [15] identified a value of 10% of left ventricular mass to be the critical substrate necessary to develop sustained ventricular arrhythmias in patients with CAD undergoing electrophysiological testing.
Quantitative Tissue Characterization of Infarct Core and Border Zone in Patients With Ischemic Cardiomyopathy by Magnetic Resonance Is Associated With Future Cardiovascular Events
2010, Journal of the American College of CardiologyCitation Excerpt :They are descriptors of myocardial and electrical dysfunctions rather than specific physiologic markers to identify patients at risk for developing CVE (20). Prior studies have demonstrated that quantification of myocardial scar volume and percentage by CMR is superior to LVEDV, LVESV, and LVEF in prognosticating future CVE, particularly ventricular arrhythmia, in patients with ICM (8,18,22–25). This study confirms that the quantification of the total scar mass by CMR can be associated with the development of CVE in patients with ICM.
