Table

Table 1. Modified Duke Criteria for the Diagnosis of IE [5]
 
Definite IE: 2 major OR 1 major + 3 minor criteria OR 5 minor criteria. Possible IE: 1 major + 1 minor OR 3 minor criteria. IE: infective endocarditis; IV: intravenous.
Major criteria1. Blood culture positive for typical microorganisms (e.g., S. aureus, Enterococcus, S. viridans); 2. Echocardiogram showing valvular vegetation.
Minor criteria1. Predisposing cardiac lesion; 2. IV drug use; 3. Fever (> 38°C); 4. Embolic phenomena; 5. Immunological phenomena (e.g., glomerulonephritis); 6. Positive blood culture not meeting above criteria.
