Measuring myocardial scar by CMR.
c r o “ e m s d r w n Late gadolinium enhancement (LGE) using cardiac magnetic resonance (CMR) has emerged as the gold-standard technique for imaging of myocardial scar. The basic principle is inversion-recovery imaging after a 5to 10-min delay following intravenous administration of gadolinium contrast (1). With appropriate settings, normal myocardium appears nulled or black, whereas nonviable...
متن کاملLate gadolinium enhancement CMR in primary mitral regurgitation.
AIMS The appropriate timing for surgery in severe asymptomatic primary mitral regurgitation (MR) remains controversial. It has been shown that late gadolinium enhancement on cardiovascular magnetic resonance (LGE CMR), which may identify myocardial fibrosis, is associated with a worse outcome in various cardiomyopathies. We sought to investigate the prevalence and significance of delayed enhanc...
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 کاملSimultaneous assessment of myocardial scar and coronary artery disease by navigator-gated 3D fat-suppressed delayed-enhancement CMR: comparison with 2D delayed-enhancement CMR, CT and CAG
Background Simultaneous assessment of myocardial scar or perfusion reduction and coronary artery stenosis is currently performed by side-by-side comparison or image fusion using coronary CTA and myocardial perfusion study, but the misregistration and differences in spatial resolution between imaging methods can be problematic. A CMR technique that can visualize both myocardial scar and coronary...
متن کاملReproducibility of late gadolidium enhancement of atrial ablation scar
Methods Eleven patients with atrial fibrillation (AF, 4 persistent) underwent first time pulmonary vein isolation procedure. 3D LGE magnetic resonance imaging (1.5T Philips Ingenia) was performed at 3 months (91 ± 15 days) post ablation (scan 1), with a reproducibility scan three days later (scan 2). 3D LGE acquisitions were performed at 10, 20 and 30 min post gadolinium (Gd, 0.2 mmol/kg) (spat...
