Abbreviations: AR indicates aortic regurgitation; AS aortic stenosis; AVA, aortic valve area circulation; AVAi, aortic valve area indexed to body surface area; LVEF, left ventricular ejection fraction; ∆P, pressure gradient between the left ventricle and aorta; and Vmax, maximum velocity.
Aortic stenosis - Echocardiography, diagnosis, grading, causes, …
Aortic stenosis is a progressive disease that leads to a gradual reduction in the orifice area. As the area is reduced, transvalvular flow resistance increases. This results in increased left ventricular load, while simultaneously affecting systemic perfusion. Aortic stenosis is a serious condition with poor long-term outcomes.
Confirmation of Aortic Stenosis Severity in Case of Discordance …
In this report, we illustrate the different flow-gradient patterns of aortic stenosis associated with discordant grading of stenosis severity at transthoracic echocardiography (TTE).
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories.

2023年4月16日 · Aortic stenosis is a common valvular disorder leading to left ventricular outflow obstruction. The anterograde velocity across the valve must be at least 2 m/sec, whereas aortic valve sclerosis is the thickening and calcification without a significant pressure gradient.
Aortic stenosis guideline published - bsecho.org
2021年5月4日 · The new guideline comprehensively covers all aspects of the echocardiographic assessment of aortic stenosis. This includes important background information such as aortic valve anatomy, the aetiology of aortic stenosis, and a description of the haemodynamics of AS.
• Move beyond peak gradient and aortic valve area as key markers to define the severity of aortic stenosis • Incorporate measures of vascular load (valve impedence) • Assess LV geometry, LV function and myocardial damage (including BNP) • Do stress test if in doubt about symptoms
