Cardiac Imaging for Diagnosis and Management of Infective Endocarditis

Imaging is central to the care of patients with infective endocarditis. Although transthoracic and transesophageal echocardiography are the principal imaging techniques, additional modalities including positron emission tomography and cardiac computed tomography, and to a lesser extent intracardiac echocardiography, play an increasing role. This review discusses the role of cardiac imaging in establishing the diagnosis of endocarditis, in predicting its embolic risk, and in making decisions regarding the need for and timing of surgery.
