BACKGROUND Microvascular ischemia is one of the hallmarks of hypertrophic cardiomyopathy (HCM) and has been associated with poor outcome. However, myocardial fibrosis, seen on cardiovascular magnetic resonance (CMR) as late gadolinium enhancement (LGE), can be responsible for rest perfusion defects in up to 30% of patients with HCM, potentially leading to an overestimation of the ischemic burde...
BACKGROUND Myotonic dystrophy type 2 (DM2) is a genetic disorder characterized by skeletal muscle symptoms, metabolic changes, and cardiac involvement. Histopathologic alterations of the skeletal muscle include fibrosis and fatty infiltration. The aim of this study was to investigate whether subclinical cardiac involvement in DM2 is already detectable in preserved left ventricular function by c...
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 ...
BACKGROUND Left ventricular (LV) rotation, twist, and torsion are important aspects of the cardiac performance. Myocardial fibrosis can be identified as the late gadolinium enhancement (LGE) in cardiac magnetic resonance (CMR). In this study, we investigated the association between myocardial fibrosis and LV rotational parameters in patients with nonischemic dilated cardiomyopathy (NDC). METH...
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...
Background 20-40% of reperfused ST-elevation acute myocardial infarction (STEMI) features microvascular obstruction (MO), which confers adverse prognosis. Different CMR sequences are commonly used to detect MO: first pass perfusion (FPP), early gadolinium enhancement (EGE), and late gadolinium enhancement (LGE). FPP and EGE are more sensitive than LGE for the detection of MO. However, only MO b...
Background Midwall septal fibrosis on late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging has been shown to be an independent predictor of adverse events in patients with non-ischemic dilated cardiomyopathy (NICM). Recent studies in other cardiomyopathy cohorts, such as Hypertrophic Cardiomyopathy, suggest that LGE extent provides incremental prognostic value over ...
BACKGROUND Cardiovascular magnetic resonance (CMR) myocardial perfusion imaging (MPI) is a state-of-the-art noninvasive modality for detection of myocardial ischemia and coronary artery disease. Magnetic resonance coronary angiography (MRCA) allows visualization of the coronary tree, but its incremental value as part of a CMR protocol including MPI and late gadolinium enhancement (LGE) is not w...
BACKGROUND Cardiovascular magnetic resonance (CMR) imaging offers methods for the detection of ischemia and myocardial infarction as well as visualization of the coronary arteries (MRCA). However, a direct comparison of adenosine perfusion (PERF), late gadolinium enhancement (LGE) and MRCA or the results of their combination has not been performed. Aim of the study was to evaluate the feasibili...
BACKGROUND The prognosis and treatment of the 2 main types of cardiac amyloidosis, immunoglobulin light chain (AL) and transthyretin (ATTR) amyloidosis, are substantially influenced by cardiac involvement. Cardiovascular magnetic resonance with late gadolinium enhancement (LGE) is a reference standard for the diagnosis of cardiac amyloidosis, but its potential for stratifying risk is unknown. ...
