We provide a host of offerings that highlight Cardiovascular Imaging advances in cardiovascular imaging to improve disease risk stratification in vari- ous cardiovascular diseases, enhance our understanding of coronavirus disease 2019 (COVID-19)–induced myocardial injury, and provide important perspectives on the ISCHEMIA trial (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches). In patients with heart failure and reduced ejection fraction, left atrial enlarge- ment and poor left atrial function assessed with a variety of indices such as phasic volume changes or strain-based measurements of reservoir, conduit, and booster pump function, are associated with poorer prognosis. Benfari et al add to this repertoire by reporting in patients with heart failure and reduced ejection frac- tion that the echocardiographically measured left atrial volumetric/mechanical cou- pling index is associated with higher grades of functional mitral regurgitation and is independently associated with mortality.
