Key result
This retrospective feasibility study investigated the Aortic Valve coefficient for assessing aortic stenosis severity, but the abstract reports no quantitative results.
Why the study?
Does the Doppler-derived Aortic Valve coefficient (AVC) correlate with current diagnostic parameters for assessing the severity of aortic stenosis?
Observational
Does the Doppler-derived Aortic Valve coefficient (AVC) correlate with current diagnostic parameters for assessing the severity of aortic stenosis?
The Doppler-derived Aortic Valve coefficient (AVC) is being investigated as a novel functional parameter for the non-invasive assessment of aortic stenosis severity.
Insufficient evidence supports AVC for aortic stenosis; leaves open correlation with standard severity parameters.
Background: Accurate assessment of the severity of stenosis is critical in patients with aortic stenosis.The ambiguities and imprecisions of the current diagnostic parameters can result in suboptimal clinical decisions.In this feasibility study, we investigate the functional diagnostic parameter AVC (Aortic Valve coefficient: ratio of the total transvalvular pressure drop to the proximal dynamic pressure) in the non-invasive assessment of the severity of aortic stenosis by correlating with the current diagnostic parameters.
