Role of transoesophageal echocardiography in infective endocarditis
| The first 150 words of the full text of this article appear below. |
Infective
endocarditis continues to be an underdiagnosed and undertreated
disease, in spite of a mortality which exceeds that of acute myocardial
infarction. In the diagnosis of this disease, echocardiography
including transoesophageal echocardiography
has been
a major breakthrough. While the traditional hallmarks of endocarditis
were fever together with a new or changed heart murmur, cutaneous
signs, and embolic events, echocardiography has enabled the direct
visualisation of endocarditic lesions. Indeed, the widely acknowledged
Duke criteria for endocarditis1 list echocardiographic signs as a major diagnostic criterion, which together with positive blood cultures allows the definite diagnosis of endocarditis (table 1).
Recent work indicates that echocardiography should have an even more
prominent place, because patients nowadays are very frequently
pretreated with antibiotics before any blood cultures are drawn,
leading to a high incidence of culture negative
endocarditis.2
