Late gadolinium enhanced (LGE) magnetic resonance imaging (MRI) is a useful tool for facilitating ventricular tachycardia (VT) ablation. Unfortunately, most VT ablation candidates often have prophylactic implantable cardioverter-defibrillator (ICD) and do not undergo cardiac MRI largely due to image artefacts generated by ICD. A prior study has reported success of 'wideband' LGE MRI for imaging myocardial scar without image artefacts induced by ICD at 1.5T. The purpose of this study was to widen the availability of wideband LGE MRI to 3T, since it has the potential to achieve higher spatial resolution than 1.5T. ⋯ This study demonstrates the feasibility of wideband LGE MRI for suppression of image artefacts induced by ICD at 3T.

The associations of mitral annular calcification (MAC) with atrial fibrillation (AF) risk factors and related outcomes suggest a possible association between MAC and AF. The aim of this study was to examine the association between MAC and AF in a racially and ethnically diverse population. ⋯ The presence of MAC was predictive of incident AF in MESA. Potentially, these findings suggest a usefulness of cardiac CT to identify individuals at risk for AF.
