Severe aortic stenosis is an important, remediable and surgically correctable cause of symptoms and death. Diagnosis in adults and differentiation from minor degrees may be difficult. Aortic valve calcification visible on radiography or fluoroscopy is a sensitive but relatively nonspecific marker for the presence of critical aortic stenosis in patients with angina, dyspnoea or syncope. In 97% of patients with critical aortic stenosis analysed calcification was detected.
重度主动脉瓣狭窄是导致症状和死亡的一个重要、可补救且可通过手术矫正的原因。在成年人中进行诊断以及与轻度病例相鉴别可能存在困难。在有胸痛、呼吸困难或晕厥的患者中，X线摄影或透视可见的主动脉瓣钙化是重度主动脉瓣狭窄存在的一个敏感但相对非特异性的标志。在所分析的重度主动脉瓣狭窄患者中，97%检测到了钙化。
