A subannular left ventricular aneurysm is very rare, and is mostly considered to be a congenital anomaly. A subannular left ventricular aneurysm is classified based on the type of its own orifice-submitral or subaortic. Subaortic left ventricular aneurysm occurs less frequently compared with a submitral type of subannular aneurysm. We hereby describe a rare case of a huge bilobed subaortic aneurysm, in which the orifice was located just below the left coronary cusp diagnosed with multimodality imaging in a child.
瓣环下左心室动脉瘤非常罕见，大多被认为是先天性异常。瓣环下左心室动脉瘤根据其自身开口类型——二尖瓣下或主动脉瓣下进行分类。与二尖瓣下型瓣环下动脉瘤相比，主动脉瓣下左心室动脉瘤的发生率更低。我们在此描述一例罕见的巨大双叶主动脉瓣下动脉瘤病例，该病例中开口位于左冠状动脉瓣尖下方，通过多种影像学检查在一名儿童中得以诊断。
