title: Mitral annular aneurysm resulting from subaortic muscle resection.
abstract: We present a case of mitral annular aneurysm as a very rare complication developing soon after the surgical relief of subaortic stenosis. The cause of the aneurysm was considered to be the disruption of aorto-mitral intervalvular fibrosa at the initial operation. The surgical repair was successfully performed without compromising either aortic or mitral valvular functions. The preoperative transesophageal echocardiography was useful in delineating the precise anatomic features of this rare complication.
