S. aureus bacteremia
routine echocardiography is justified in this the frequency of IE in this setting and of the virulence of this organism, and its devastating effects
Criterios mayores ecográficos
vegetation, abscess, and new dehiscence of a prosthetic valve
The sensitivity of TTE ranges from (*) and that of TEE
from (*)
- 40 to 63%
- 90 to 100%
Appearances resembling vegetations may be seen in
degenerative or myxomatous valve disease, systemic lupus (inflammatory Libman – Sacks lesions), and rheumatoid disease, primary antiphospholipid syndrome, valvular thrombus, advanced malignancy (marantic endocarditis), chordal rupture, and in association with small intracardiac tumours (typically fibroelastomata).
In cases with an initially negative examination, repeat TTE/TEE must be performed
7–10 days later if the clinical level of suspicion is still high, or even earlier in case of S. aureus infection Additional
echocardiographic study is seldom helpful, with little additional information derived after the second or third assessment.
