Educational Pearls:
- Variability of organisms in infecting the myocardial valves
- Duke Criteria for Infective Endocarditis includes three categories that can be used to definitively diagnose endocarditis
- Pathologic Criteria
- pathological evidence of infection
- Major Clinical Criteria
- positive blood cultures
- positive echocardiogram findings (TEE is more sensitive than a TTE)
- Minor Clinical Criteria (must include all of the below criteria)
- Fever
- Underlying heart condition or IV drug use
- Vascular phenomena (includes Janeway's lesions)
- Immunologic phenomena (includes Osler's nodes, Roth spots)
- Positive blood cultures or serologic evidence of infection with bacteria known to cause endocarditis
- Some studies show up to a 33% one-year mortality of people diagnosed with endocarditis
- This criteria was developed by David Durack, MD and he was affiliated with Duke University, shout out to Dr. Pete Bakes!
