Diagnostic de la probabilité de risque d’Endocardite Infectieuse et de l’intérêt de l’Echocardiographie Trans-Oesophagienne en cas de bactériémie à Entérocoque

The DENOVA score is a clinical decision tool used to identify patients with Enterococcus faecalis bacteremia (bloodstream infection) who are at low risk for infective endocarditis (IE) and do not need a transesophageal echocardiogram.How it WorksThe DENOVA score expands on the older NOVA score by adding criteria for symptom duration and embolic events. It assigns points based on clinical and laboratory variables:N: Number of positive blood culturesO: Origin of infection unknownV: Valve diseaseA: Auscultation of murmurD: Duration of symptoms / persistent bacteremiaE: Embolization / vascular phenomenaClinical CutoffA score ≥ 3 points indicates a high risk for infective endocarditis, meaning an echocardiogram is recommended.A score < 3 points helps safely rule out infective endocarditis and avoid unnecessary diagnostic tests like transesophageal echocardiography.You can access the interactive tool via the DENOVA Score on QxMD or check the Medscape DENOVA Reference.If you are looking at a specific patient case, please share:Whether there is a known primary source of infectionThe number of positive blood culturesAny signs of new murmurs or embolizationI can help explain how the scoring breakdown applies.
