269
Inclusion Criteria
  • Patients older than 18 years
  • Suspected endocarditis: Patients with Duke-Li-ESC 2015 classification as a major morphological criterion or at least two minor criteria, other than a microbiological criterion, will be considered suspicious of infectious endocarditis.
  • Not objecting to their inclusion in the study after delivery and explanation of the information form.
  • Absence of microbiological documentation sought or available at the time of inclusion (a patient having already had negative blood cultures or being identified during the screening can be included).
Exclusion Criteria
  • Antibiotherapy adapted to a situation of endocarditis, introduced more than 24 hours or stopped for less than 7 days in case of therapeutic window.
  • Any previous antibiotic therapy in the 7 days preceding the inclusion leading to an improvement in the clinical symptomatology.
  • State of consciousness not allowing loyal information.

Primary Outcome Measures
NameTimeMethod
Compared performance of a single high volume blood culture vs. multiple blood culture of usual volume for the diagnosis of infective endocarditisAt the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

Sensitivity/Specificity/Accuracy of positive bloodculture sets vs. final diagnosis assessed by the medical team (gold standard)

Secondary Outcome Measures
NameTimeMethod
Diagnostic performance of the single high volume blood culture for the diagnosis of infective endocarditisAt the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

according to the level of suspicion of infective endocarditis, the type of microorganism involved, the underlying cardiopathy.

Diagnosis of infective endocarditis: confirmed, possible or excludedAt the end of the hospitalization, or at the time of death if occurred during hospitalization; i.e. an average of 6 weeks after the inclusion

Applying the Classification of Duke-Li according to the modified diagnostic criteria of the European Society of Cardiology Recommendations 2015.
