Prognostic Implications of Left Ventricular Scar Determined by Late Gadolinium Enhanced Cardiac Magnetic Resonance in Patients with Atrial Fibrillation
Left ventricular (LV) scar identified by late gadolinium enhanced (LGE) cardiac magnetic resonance (CMR) is associated with adverse outcomes in coronary artery disease (CAD) and cardiomyopathies. We sought to determine the prognostic significance of LV-LGE in atrial fibrillation (AF). We studied 778 consecutive patients referred for radiofrequency ablation of AF who underwent CMR. Patients with CAD, prior myocardial infarction (MI), or hypertrophic or dilated cardiomyopathy were excluded. The endpoints of interest were major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of cardiovascular death, MI and ischemic stroke/transient ischemic attack (TIA).
