Key result
M-mode echocardiography detects a large subvalvar aortic root aneurysm complicating infective endocarditis.
Why the study?
Echocardiographic detection of subvalvar aortic root aneurysm extending to the mitral valve annulus as a complication of aortic valve endocarditis is not well characterized.
Case Report (n=1)
M-mode echocardiography can effectively detect complex structural complications of infective endocarditis, such as subvalvar aortic root aneurysms.
May aid detection of rare IE complications; hypothesis-generating and should not yet change practice.
Acute aortic regurgitation as a consequence of infective endocarditis developed in a young man after peritonitis. A large subvalvar aortic root aneurysm extending to the mitral valve annulus together with features of severe acute aortic regurgitation were shown by M-mode echocardiography. The echocardiographic findings were confirmed at operation when obliteration of the aneurysmal space and aortic valve replacement were performed. Postoperative echocardiography confirmed obliteration of the aneurysmal space.

Griffiths et al. (1982) conducted a case report in Infective endocarditis with acute aortic regurgitation (n=1). M-mode echocardiography was evaluated. M-mode echocardiography successfully identified a large subvalvar aortic root aneurysm extending to the mitral valve annulus as a complication of infective endocarditis, confirmed surgically.
