Extent of late gadolinium enhancement detected by cardiovascular magnetic resonance correlates with the inducibility of ventricular tachyarrhythmia in hypertrophic cardiomyopathy
BACKGROUND Myocardial fibrosis is frequently identified in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to investigate the role of myocardial fibrosis detected by late gadolinium-enhancement (LGE) cardiovascular magnetic resonance (CMR) as a potential arrhythmogenic substrate in HCM. We hypothesized that the extent of LGE might be associated with the inducibility o...
متن کاملLate gadolinium enhancement in cardiovascular magnetic resonance in patients with hypertrophic cardiomyopathy complicated by life-threatening ventricular tachyarrhythmia.
BACKGROUND Late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR) has been shown to be associated with ventricular arrhythmias, however, its prognostic role in predicting sudden cardiac death has not yet been established. AIM To explore a potential relationship between LGE visualised by CMR and life-threatening ventricular tachyarrhythmia in hypertrophic cardiomyopathy ...
متن کاملIntermediate-signal-intensity late gadolinium enhancement predicts ventricular tachyarrhythmias in patients with hypertrophic cardiomyopathy.
BACKGROUND In hypertrophic cardiomyopathy (HCM), the arrhythmic potential associated with a variety of left ventricular myocardial signal intensities evident on contrast-enhanced cardiovascular magnetic resonance with late gadolinium enhancement (LGE) is unresolved. METHODS AND RESULTS In 145 HCM patients (43±15 years old), visually identified areas of LGE in left ventricle were analyzed quan...
متن کاملIschemic late gadolinium enhancement.
While research exploring the utility of intravascular gadolinium based contrast agents (GBCA), such as gadofosveset (Vasovist, ABLAVAR) is ongoing, cardiac MR is currently routinely performed with administration of standard extracellular GBCAs, e.g. Gd-DTPA (Magnevist) or Gd-BOPTA (Multihance). LGE is a phenomenon related to the distribution of the extracellular GBCAs. Upon intravenous injectio...
