Aortic subannular ventricular aneurysms.
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.
