Abstract
Severe Aortic stenosis (AS) is characterised by a late peaking crescendo-decrescendo systolic murmur and a diminished/absent second heart sound. Echocardiographic assessment of AS severity, based on transvalvular velocities / pressure gradients and calculated aortic valve area (AVA), confirms the diagnosis and allows timely intervention. Nevertheless, diagnostic uncertainty exists in cases of discordant measurements, confounders, and symptoms-measurement discrepancies. This guide outlines an approach to the use of multimodal imaging in the diagnosis and staging of AS.
重度主动脉瓣狭窄(AS)的特征是收缩期杂音呈渐强-渐弱的晚期峰值,第二心音减弱/消失。根据跨瓣速度/压力梯度和计算的主动脉瓣面积(AVA)对主动脉瓣狭窄的严重程度进行超声心动图评估可确诊并及时进行干预。然而,在测量结果不一致、混杂因素和症状与测量结果不符的情况下,诊断仍存在不确定性。本指南概述了在 AS 诊断和分期中使用多模态成像的方法。
