Summary

Infective endocarditis (IE) can cause severe aortic and mitral valve damage, necessitating valve replacement. Post-surgery, patients may develop periprosthetic mitral regurgitation, requiring ongoing monitoring.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Cardiac Surgery

Background:

  • Infective endocarditis (IE) is a serious infection affecting heart valves.
  • Early diagnosis and intervention are crucial for managing IE complications.

Observation:

  • A 63-year-old male presented with acute heart failure due to IE.
  • Echocardiography revealed aortic and mitral valve vegetation, aneurysm, perforation, and severe regurgitation.

Findings:

  • Surgical aortic and mitral valve replacement was performed.
  • The patient completed 6 weeks of antibiotic therapy and recovered neurologically.
  • Postoperative echocardiography identified periprosthetic mitral regurgitation.

Implications:

  • This case highlights unusual complications of aortic valve IE.
  • Prompt surgical intervention and close follow-up are essential for managing complex IE cases.
  • Periprosthetic valve complications require vigilant monitoring after valve replacement surgery.
