Aortic stenosis (AS) is the most common valvular heart disease growing in parallel to the increment of life expectancy. Besides the valve, the degenerative process affects the aorta, impairing its elastic properties and leading to increased systemic resistance. The composite of valvular and systemic afterload mediates ventricular damage. The first step of a thorough evaluation of AS should include a detailed assessment of valvular anatomy and hemodynamics. Subsequently, the ventricle, and the global afterload should be assessed to define disease stage and prognosis. Multimodality imaging is of paramount importance for the comprehensive evaluation of these three elements. Echocardiography is the cornerstone modality whereas Multi-Detector Computed Tomography and Cardiac Magnetic Resonance provide useful complementary information. This review comprehensively examines the merits of these imaging modalities in AS for the evaluation of the valve, the ventricle, and the afterload and ultimately endeavors to integrate them in a holistic assessment of AS.

用于主动脉瓣狭窄整体评估的多模态成像：瓣膜、心室、后负荷

主动脉瓣狭窄（AS）是最常见的瓣膜性心脏病，其发病率与预期寿命的增加同步增长。除了瓣膜外，退行性过程还会影响主动脉，损害其弹性并导致全身阻力增加。瓣膜和全身后负荷的复合介导心室损伤。彻底评估 AS 的第一步应包括对瓣膜解剖结构和血流动力学的详细评估。随后，应评估心室和整体后负荷以确定疾病阶段和预后。多模态成像对于这三个要素的综合评价至关重要。超声心动图是基石模式，而多探测器计算机断层扫描和心脏磁共振提供有用的补充信息。这篇综述全面考察了这些成像方式在 AS 中评估瓣膜、心室和后负荷的优点，并最终努力将它们整合到 AS 的整体评估中。
