Infective endocarditis patients undergoing valve replacement often experience septic emboli, leading to acute extremity ischemia. Prompt diagnosis and management, prioritizing valve replacement, are crucial for limb salvage.

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Infectious Diseases

Background:

  • Infective endocarditis (IE) can lead to embolic complications.
  • Septic emboli may complicate cardiac valvular prosthesis placement.
  • Peripheral vascular consequences of IE emboli require evaluation.

Purpose of the Study:

  • To evaluate vascular consequences of septic emboli in IE patients.
  • To assess outcomes of valve replacement and embolic management.

Main Methods:

  • Retrospective review of 102 patients with IE undergoing valve replacement over 15 years.
  • Identification of patients with septic embolization and extremity occlusive events.
  • Analysis of clinical presentation, diagnostic methods (angiography), and treatment strategies.

Main Results:

  • 31 patients (30%) had 36 septic embolization episodes; 10 involved extremities.
  • Peripheral emboli presented as acute extremity ischemia, often limb-threatening.
  • Gram-positive bacteria were common; angiography confirmed diagnosis in most cases.
  • Valve replacement preceded or coincided with vascular procedures; outcomes varied.

Conclusions:

  • IE requiring valve replacement is associated with embolization in one-third of patients.
  • Peripheral vascular emboli manifest as acute extremity ischemia.
  • Angiography is vital for diagnosis; valve replacement should precede vascular intervention when feasible.
