Overview
Common signs on physical examination of endocarditis include fever, presence of a new or changing heart murmur, rigors, Osler's nodes, Janeway lesions and evidence of embolization. Aortic insufficiency with a wide pulse pressure, mitral regurgitation or tricuspid regurgitation may be present depending upon the valve that is infected.
Physical Examination
Appearance of the Patient
- Patients with endocarditis usually appear ill.[1][2]
Vital Signs
- A fever will likely be present.
- Rigors may be present.
- Some patients may have a wide pulse pressure due to aortic insufficiency. If the pulse pressure narrows, this may be a sign of left ventricular failure due to earlier closure of the mitral valve and a more rapid rise in the left ventricular end diastolic pressure which will in turn raise the diastolic pressure.
Skin
- Petechiae are present in 10% to 40% of patients
- Splinter hemorrhages are present in 5% to 15% of patients
- Osler's nodes which are tender subcutaneous nodules in pulp of digits are present in 7% to 10% of patients
- Janeway lesions which are erythematous, nontender lesions on palm or sole are present in 6% to 10% of patients

Oral Cavity
Examine the oral cavity:
- Poor oral hygiene
- Teeth looking for periodontitis, plaque and calculus
- Gingiva looking for gingivitis
- Recent dental procedure
HEENT
- Conjunctival hemorrhage
- Roth's spots in the retina
- Bobbing of the uvula may be present among patients with new onset aortic regurgitation.

Neck
- Neck examination of patients with endocarditis is usually normal.
Lungs
- Signs of heart failure such as rales may present
Heart
- Heart murmurs are present in 80% to 85% of patients including that of aortic insufficiency, tricuspid regurgitation and mitral regurgitation.[3]
Abdomen
- Abdominal pain may be present due to mesenteric embolization or ileus both of which may manifest as reduced bowel sounds.
- Splenomegaly may be present in 15% to 30% patients.
- Left upper quadrant pain (LUQ pain) may be present as a result of a splenic infarct from embolization.
- Flank pain may be present as a result of an embolus to the kidney.
Back
- Back examination of patients with endocarditis is usually normal
Genitourinary
- Genitourinary examination of patients with endocarditis is usually normal.
Neurologic
- Septic emboli may result in stroke and focal neurologic findings[4]
- Seizures may be present
- Intracranial hemorrhage may occur
- Signs of a brain abscess may be present
Extremities
- Janeway lesions (painless hemorrhagic cutaneous lesions on the palms and soles)
- Gangrene of fingers may occur
- The fingers may show splinter haemorrhages
- Osler's nodes (painful subcutaneous lesions in the distal fingers)
