Differentiation of bicuspid aortic valve from other causes of calcific aortic stenosis is not possible by echocardiography or, in many cases, by aortography. This report describes newly recognized patterns of calcification on plain films that are diagnostic for a bicuspid aortic valve. These are based on identification of the calcified raphe and/or the calcified conjoint leaflet. In 120 patients who underwent surgical repair of calcific aortic stenosis, 40 were found to have bicuspid valve. Examination of the plain films retrospectively allowed a correct recognition of 26 (65%) of these valves. In contrast, only 10 (25%) could be recognized by aortography. Patterns of calcification on plain films represent an important tool for detection of calcified cogenital bicuspid aortic valve.
通过超声心动图，或者在许多情况下通过主动脉造影，无法将二叶式主动脉瓣与其他导致钙化性主动脉瓣狭窄的病因区分开来。本报告描述了X线平片上新发现的可诊断二叶式主动脉瓣的钙化模式。这些模式基于对钙化嵴和/或联合钙化瓣叶的识别。在120例行钙化性主动脉瓣狭窄手术修复的患者中，发现40例为二叶式瓣膜。回顾性检查X线平片能够正确识别其中26例（65%）的瓣膜。相比之下，主动脉造影仅能识别10例（25%）。X线平片上的钙化模式是检测先天性钙化性二叶式主动脉瓣的一项重要工具。
