[Cardiac ultrasonography in the diagnosis and monitoring of infectious endocarditis].

Transthoracic and transoesophageal doppler echocardiography has become an essential tool for the diagnosis of infective endocarditis. It detects valvular vegetations and destructions, evaluates regurgitations, and appreciates haemodynamic tolerance. Recognition of endocarditis, early identification of high-risk patients, and detection of mechanical complications are the most accurate informations derived from this technique. Transoesophageal echocardiography has the potential to avoid the difficulties encountered using the transthoracic approach, and it must be used particularly in the presence of non diagnostic transthoracic examination when clinical suspicion is high.
