The prospective role of transesophageal echocardiography in the diagnosis and management of patients with suspected infective endocarditis.

Study Objectives: Transesophageal echocardiography (TEE) has a high sensitivity for the diagnosis of infective endocarditis (IE), but the prospective role of TEE when added to a careful clinical examination has not been well-studied.

Design: We compared the results of TEE to a clinical evaluation by an infectious disease specialist in 43 consecutive patients in whom TEE was ordered to rule out IE. Prior to TEE, the patients were classified on clinical grounds as to their likelihood of IE using a modification of the von Reyn criteria.
