Subannular aneurysms of the left ventricle are rare aneurysms originating adjacent to the aortic or mitral valve. Mitral subannular aneurysms are more common and have been well described. Two cases of aortic subannular aneurysm are reported, and an additional 20 cases were found in the literature. These aneurysms are usually found in young adults who may be seen with congestive heart failure, cardiac murmurs, angina pectoris, myocardial infarction, or even rupture. The aneurysms are often associated with aortic valve anomalies or subaortic stenosis. Diagnosis can be made by echocardiography and cardiac catheterization, and surgical repair is indicated.
左心室瓣环下动脉瘤是起源于主动脉瓣或二尖瓣附近的罕见动脉瘤。二尖瓣瓣环下动脉瘤更为常见且已有充分描述。本文报告了2例主动脉瓣环下动脉瘤病例，并在文献中另外发现20例。这些动脉瘤通常见于年轻人，可能伴有充血性心力衰竭、心脏杂音、心绞痛、心肌梗死甚至破裂。动脉瘤常与主动脉瓣异常或主动脉瓣下狭窄相关。可通过超声心动图和心导管检查做出诊断，且需进行手术修复。
