Why the study?
The presence of an abnormal intracardiac structure in the setting of occult infection raises the suspicion of infective endocarditis.
Detailed 2D and 3D transesophageal echocardiography is effective for identifying rare congenital mitral valve anomalies such as a mitral annular fibrous band and ruling out infective endocarditis.

May aid diagnosis of rare mitral anomalies; leaves open need for prospective validation before wider adoption.
The presence of an abnormal intracardiac structure in the setting of occult infection should always raise the suspicion of infective endocarditis. Using detailed 2D multiplanar and 3D transoesophageal echocardiography, we were able to identify the anomalous band and exclude any overt infective vegetations attached to the band or the leaflets. Once identified, treatment options range from conservative management to surgical resection and mitral valve surgery if concomitant valvular dysfunction is demonstrated.
