Risk Stratification of Severe Aortic Stenosis With Preserved Left Ventricular Ejection Fraction Using Peak Aortic Jet Velocity: An Outcome Study [Valvular Heart Disease]
Conclusions— Our results demonstrate the strong relationship between Vmax and mortality in patients with severe AS and preserved left ventricular ejection fraction irrespective of symptoms. Vmax ≥5 m/s at the time of AS diagnosis identifies patients with very severe AS at high risk of death. (Source: Circulation: Cardiovascular Imaging)

Preload Stress Echocardiography Predicts Outcomes in Patients With Preserved Ejection Fraction and Low-Gradient Aortic Stenosis [Valvular Heart Disease]
Conclusions— In patients with low-gradient AS, indexed AVAproj derived from preload stress echocardiography can be useful to predict risk of adverse events. The present article should be considered as a proof of concept study, and we think that larger multicenter studies are warranted. (Source: Circulation: Cardiovascular Imaging)

Age, Sex, and Blood Pressure-Related Influences on Reference Values of Left Atrial Deformation and Mechanics From a Large-Scale Asian Population [Atrial Structure and Function]
Conclusions— Our findings suggest LA mechanical functional decays in association with increasing age and higher blood pressure, which seem to be compensated for by augmentation of atrial pump function. We have also provided age- and sex-stratified reference values for strain and SR based on a large-scale Asian population. (Source: Circulation: Cardiovascular Imaging)

Presence, Characteristics, and Prognostic Associations of Carotid Plaque Among People Living With HIV [Peripheral Arterial Disease]
Conclusions— There is an increase in incidental carotid plaque, noncalcified plaque, and high-risk plaque among PLWHIV, and the presence and characteristics of carotid plaque are associated with subsequent vascular events. (Source: Circulation: Cardiovascular Imaging)

Multimodality Intracoronary Imaging With Near-Infrared Spectroscopy and Intravascular Ultrasound in Asymptomatic Individuals With High Calcium Scores [Intravascular Imaging]
Conclusions— Among individuals with a CACS ≥300 Agatston units mostly on statins, CACS correlated with total plaque volume but not LCBI. This observation may have implications on coronary risk among individuals with a high CACS considering that it is coronary LRP, rather than calcification, that underlies the majority of acute coronary events.

Coronary Artery Calcium Distribution Is an Independent Predictor of Incident Major Coronary Heart Disease Events: Results From the Framingham Heart Study [Coronary Artery Disease]
Conclusions— Distribution of coronary atherosclerosis, especially CAC in the proximal dominant coronary artery and an increased number of coronary arteries with CAC, predict major CHD events independently of the traditional AS in community-dwelling men and women.

Metoprolol Reduces Hemodynamic and Metabolic Overload in Asymptomatic Aortic Valve Stenosis Patients: A Randomized Trial [Ventricular Structure and Function]
Conclusions— In patients with asymptomatic AS, metoprolol increases systolic ejection time and reduces aortic valve gradients, global afterload, and myocardial oxygen requirements. Thus, metoprolol displays favorable hemodynamic and metabolic effects and could improve outcome in patients with asymptomatic AS. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT02076711. (Source: Circulation: Cardiovascular Imaging)

Machine Learning Approaches in Cardiovascular Imaging [Advances in Cardiovascular Imaging]
Cardiovascular imaging technologies continue to increase in their capacity to capture and store large quantities of data. Modern computational methods, developed in the field of machine learning, offer new approaches to leveraging the growing volume of imaging data available for analyses. Machine learning methods can now address data-related problems ranging from simple analytic queries of existing measurement data to the more complex challenges involved in analyzing raw images. To date, machine learning has been used in 2 broad and highly interconnected areas: automation of tasks that might otherwise be performed by a hum...
