Podcast 762: Endocarditis

Contributor: Jared Scott, MD

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!
