Low Relative Valve Load is Associated With Paradoxical Low-Flow Aortic Stenosis Despite Preserved Left Ventricular Ejection Fraction and Adverse Clinical Outcomes.

Heart Lung Circ 2021 Jun 8. Epub 2021 Jun 8.

Department of Cardiology, National University Heart Centre Singapore, National University Health System, Singapore; Yong Loo Lin School of Medicine, National University of Singapore, Singapore. Electronic address:

Background: Paradoxical low-flow (LF) severe aortic stenosis (AS) despite preserved left ventricular (LV) ejection fraction (LVEF) has been shown to be distinct from normal-flow (NF) AS, with a poorer prognosis. Relative valve load (RVL) is a novel echocardiographic haemodynamic index based on the ratio of transaortic mean pressure gradient to the global valvulo-arterial impedance (Zva) in order to estimate the contribution of the valvular afterload to the global LV load. We aimed to determine the usefulness of RVL in LF AS versus NF AS. Read More

First-phase ejection fraction by cardiovascular magnetic resonance predicts outcomes in aortic stenosis.

J Cardiovasc Magn Reson 2021 Jun 10;23(1):73. Epub 2021 Jun 10.

British Heart Foundation Centre of Research Excellence, King's College London, London, UK.

Background: First-phase ejection fraction (EF1; the ejection fraction measured during active systole up to the time of maximal aortic flow) measured by transthoracic echocardiography (TTE) is a powerful predictor of outcomes in patients with aortic stenosis. We aimed to assess whether cardiovascular magnetic resonance (CMR) might provide more precise measurements of EF1 than TTE and to examine the correlation of CMR EF1 with measures of fibrosis.

Methods: In 141 patients with at least mild aortic stenosis, we measured CMR EF1 from a short-axis 3D stack and compared its variability with TTE EF1, and its associations with myocardial fibrosis and clinical outcome (aortic valve replacement (AVR) or death). Read More
