Non-contrast T1 mapping characterizes the myocardium beyond that achieved by late gadolinium enhancement in both hypertrophic and dilated cardiomyopathy
Background Both HCM and DCM exhibit variable clinical outcomes. Unfortunately, our ability to risk stratify and characterize disease mechanisms in these patients remains poor, and improved biomarkers are needed. Myocardial fibrosis, both focal and diffuse, is a feature of both HCM and DCM and focal myocardial fibrosis, as assessed by LGE, has been recently identified as a predictor of cardiac d...
متن کاملLate gadolinium enhancement in non-compaction cardiomyopathy.
The European Society Cardiology of currently considers the non-compaction cardiomyopathy as an un-classified cardiomyopathy.1 It is characterised by the presence of numerous and prominent trabeculations together with deep intertrabecular recesses in a portion of the ventricular wall, principally at the lateral, and apical level, as a result of a congenital anomaly of the endomyocardial developm...
متن کاملComparison of Semi-automated Late Gadolinium Enhancement Quantification Techniques in Measuring Septal Fibrosis in Patients with Dilated Non-Ischemic Cardiomyopathy
Background Mid-wall striae pattern late gadolinium enhancement (LGE) has been shown to independently predict future outcomes in patients with dilated non-ischemic cardiomyopathy (NICM). Standardized quantification tools are of particular interest for clinical translation of this novel imaging marker. However, signal intensity (SI) based threshold techniques, such as Signal Threshold versus Refe...
متن کاملComparison of electroanatomic voltage mapping with late gadolinium enhancement CMR
Background Atrial fibrillation (AF) is associated with atrial remodeling, including atrial cellular pathology [1,2], left atrial enlargement [3], and low voltage on electroanatomic mapping (EAM)[4]. Recent studies have identified late gadolinium enhancement (LGE) in AF subjects pre-PVI as novel evidence of LA remodeling [5]. One study compared voltage by EAM obtained prior to a pulmonary vein i...
متن کاملMyocardial fibrosis delineation in late gadolinium enhancement images of Hypertrophic Cardiomyopathy patients using deep learning methods
Introduction: Accurate delineation of myocardial fibrosis in Late Gadolinium Enhancement on Cardiac Magnetic Resonance (LGE-CMR) has a crucial role in the assessment and risk stratification of HCM patients. As this is time-consuming and requires expertise, automation can be essential in accelerating this process. This study aims to use Unet-based deep learning methods to automate the mentioned ...
