1

What it is / why it matters

  • Infection of valves/endocardium — native or prosthetic, often IVDU-related.
  • High morbidity; complications are frequent and time-sensitive.
2

Key diagnostic clues

  • Fever + new or changing murmur.
  • Risk: prosthetic valve, IVDU, prior IE, intracardiac device.
  • Emboli: splinter hemorrhages, Janeway lesions, Osler nodes, Roth spots; splenic/CNS emboli.
3

Initial workup

  • Draw ≥3 sets of blood cultures BEFORE antibiotics (spaced).
  • Echo (TTE → TEE if high suspicion or prosthetic); apply Duke-ISCVID criteria; inflammatory markers.
4

Management framework

  • Targeted, prolonged IV antibiotics (ID-guided).
  • Surgery for heart failure, uncontrolled infection, large mobile vegetation with emboli, abscess, or prosthetic dehiscence.
  • Manage with an endocarditis team.
5

Red flags / escalate now

  • Heart failure from acute regurgitation, persistent bacteremia/sepsis, embolic events.
  • New heart block suggests a perivalvular abscess → urgent surgical evaluation.
6

Follow-up / monitoring

  • Complete the antibiotic course; repeat imaging; dental/source control; prophylaxis education for high-risk patients.
7

Clinic pearls

  • Cultures BEFORE antibiotics; new murmur + fever = IE until proven otherwise.
  • New conduction block → think abscess (emergency). Consider Staph aureus, especially IVDU/prosthetic.
