Aortic stenosis (AoS) is a relatively common condition in elderly patients. It has different clinical manifestations from AoS seen in young individuals. We examined the manifestations of AoS in the elderly with emphasis on the findings that noninvasive techniques provide. Our study involved a retrospective analysis of 23 patients over 60 years old with diagnosis of calcified AoS established by hemodynamic studies. Calcification of the aortic valve on chest X-ray, left ventricular ejection time (LVET), from of the carotid pulse and thickness of ventricular walls by echocardiography proved to be useful variables for qualitative evaluation. The presence of syncope, murmur in mid-and end-systole and paradoxical splitting of the second sound as well as a LVET of more than 110% indicate a transaortic gradient greater than 50 mmHg. We conclude that evaluation by cardiac catheterization is required only in selected cases.
主动脉瓣狭窄（AoS）在老年患者中是一种相对常见的病症。它与年轻个体中所见的主动脉瓣狭窄有不同的临床表现。我们研究了老年患者主动脉瓣狭窄的表现，重点关注非侵入性技术所提供的发现。我们的研究涉及对23例60岁以上经血流动力学研究确诊为钙化性主动脉瓣狭窄的患者进行回顾性分析。胸部X线检查显示的主动脉瓣钙化、左心室射血时间（LVET）、颈动脉搏动形态以及超声心动图显示的心室壁厚度被证明是定性评估的有用变量。晕厥的存在、收缩中期和晚期杂音、第二心音反常分裂以及左心室射血时间超过110%表明跨主动脉压差大于50 mmHg。我们得出结论，仅在特定病例中才需要进行心导管检查评估。
