RESUMEN

In all patients with Staphylococcus aureus bacteraemia a transoesophageal echocardiogram is recommended to exclude infective endocarditis. We determined that a finding of normal to trivial valvular regurgitation on transthoracic echocardiogram in these patients significantly reduced the probability of infective endocarditis. Furthermore, in the absence of embolic phenomena the likelihood of infective endocarditis was less than 2%. This probability could be further reduced if the echocardiogram was performed greater than 5 days after the bacteraemia. Therefore, in the assessment of patients with S. aureus bacteraemia a transoesophageal echocardiogram is not always required to exclude infective endocarditis.
