CMR-derived left atrial reservoir strain and the LAVI/LVEF ratio are associated with 30-day readmission in atrial fibrillation: the CMRRADAR-AF retrospective cohort study
Background Cardiovascular magnetic resonance (CMR) imaging allows simultaneous evaluation of cardiac structure, function, and tissue composition. Whether CMR-derived left atrial (LA) reservoir strain, the left atrial volume index–left ventricular ejection fraction (LAVI/LVEF) ratio, and atrial late gadolinium enhanceme...
