Imaging of Low-Gradient Severe Aortic Stenosis [PDF]

, 2013
Although most patients with severe aortic stenosis (AS) have high peak velocity and mean transvalvular gradient, there is a subset of patients with low-flow, low-gradient severe AS (LGSAS).

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 898-905, October 2026.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

Surgical Versus Transcatheter Aortic Valve Replacement in Low-Flow, Low-Gradient Aortic Stenosis: Results From 1900 Patients

The Heart Surgery Forum
Background: Low-flow, low-gradient (LFLG) aortic stenosis (AS) is associated with high-risk physiology and poor outcomes; however, the optimal intervention strategy, surgical aortic valve replacement (SAVR) versus transcatheter aortic ...

Fourier Shell Analysis: k‐Space‐Based Metrics for Assessing Super‐Resolution in 4D Flow MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1983-1990, October 2026.
ABSTRACT Purpose To support the emerging field of super‐resolution (SR) in 4D flow MRI by proposing Fourier shell analysis to disentangle resolution enhancement from denoising effects during evaluation. Methods A thoracic aortic 4D flow MRI dataset was synthesized with various degrees of stenosis, providing ground truth flow fields generated using ...

Changes and Prognostic Implications of Myocardial Work in Aortic Stenosis Subtypes Undergoing Transcatheter Valve Implantation

JACC: Advances
Background: Evaluation of left ventricle (LV) systolic function in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) is challenging, as LV ejection fraction (LVEF) and global longitudinal strain are afterload ...

Early Multicenter Outcomes of Dedicated Transcatheter Aortic Valve Replacement for Left Ventricular Assist Device‐Associated Pure Aortic Regurgitation

Artificial Organs, Volume 50, Issue 10, Page 1427-1433, October 2026.
LVAD‐associated aortic regurgitation impairs circulatory support, with limited surgical and off‐label options. In a multicenter registry (n = 30), the AR‐dedicated JenaValve Trilogy TAVR eliminated AR, achieving 96.7% (29/30) technical success and 93.3% (28/30) device success (VARC‐3), with 3.3% (1/30) 30‐day mortality.
