A desktop-sized cardiac modeling system made of pliable, 3D-printed materials can be customized to accurately mimic the hydrodynamics of individual patients’ aortic stenosis, ventricular remodeling and diastolic dysfunction.
Adjustable Soft Robotic Sleeve Mimics Complex Hemodynamics of Aortic Stenosis
A novel soft robotic device designed to fit around the ascending aorta promises to enable high-fidelity simulation of the hemodynamics and biomechanics of aortic stenosis and congenital valve disease.
Supplemental Calcium Tied to Increased Mortality and AVR in Older Patients With Aortic Stenosis
A large observational study suggests that supplemental calcium exerts a detrimental effect in patients over age 60 with aortic stenosis, especially in those not undergoing aortic valve replacement.
Perspectives on the 2020 ACC/AHA Guideline for Valvular Heart Disease: Focus on the Aortic Valve
Three of our valve disease experts reflect on key changes and developments related to aortic valve disease in the new guideline update.

Higher Positioning of SAPIEN 3 Valve Reduces Conduction Abnormalities and Pacemaker Requirements
A novel technique that implants the balloon-expandable valve just 1.5 mm under the noncoronary cusp improves outcomes in transcatheter aortic valve replacement, finds a new Cleveland Clinic study.
Aortic Valve Replacement in Young and Middle-Aged Adults: New Data to Guide Decision-Making
Among patients 55 or younger, TAVR use is growing but carries a higher risk of stroke than surgical aortic valve replacement, finds an STS database analysis. We explore evolving options for AVR in younger patients.
Recent U.S. Progress Against Aortic Stenosis Mortality Has Not Been Uniform
Mortality differs from state to state and between nonwhite and white demographic groups, finds a new analysis of nationwide data since 2008.
TAVR More Apt to Help Than Harm in CKD, PARTNER Subanalysis Shows
A pooling of data from several PARTNER trials shows that chronic kidney disease was highly prevalent and that TAVR was associated with stable or improved kidney function in a large majority of cases.
Survival After TAVR Better in Patients with Mixed Aortic Valve Disease Vs. Pure Aortic Stenosis
Findings of better post-TAVR survival in mixed aortic valve disease compared with pure aortic stenosis suggest that hearts already exposed to aortic regurgitation may better tolerate mild post-TAVR regurgitation.
A New Marker for Assessing Severity of Aortic Stenosis?
The time interval between left ventricular and aortic systolic pressure peaks is associated with severity of aortic stenosis, a study suggests. The effect is strongest in patients with low mean pressure gradient.
