A case study highlights recurrent prosthetic valve endocarditis (PVE) despite using a silver-coated mechanical valve. Further clinical trials are needed to assess the benefits of silver-coated prostheses for preventing PVE.

Area of Science:

  • Cardiovascular Surgery
  • Infectious Diseases
  • Biomaterials Science

Background:

  • Prosthetic valve endocarditis (PVE) remains a significant risk following valve replacement surgery.
  • Silver-coated sewing rings (Silzone) were introduced to mitigate peri- and postoperative microbial infection.
  • The efficacy of silver-coated prostheses in preventing PVE requires further clinical evaluation.

Observation:

  • A patient with aortic stenosis underwent mechanical valve replacement with a Silzone prosthesis.
  • Early PVE developed, leading to reoperation and reimplantation of a second Silzone prosthesis, which also became infected.
  • Subsequent operations involved homograft implantation and treatment for a pseudoaneurysm.

Findings:

  • Prosthetic valve endocarditis was confirmed by clinical signs, echocardiography, and positive blood cultures for Staphylococcus epidermidis.

  • Recurrent infections occurred despite the use of silver-coated valve prostheses.
  • The patient required multiple reoperations, including homograft implantation.

    • Implications:

    • This case underscores the persistent risk of endocarditis associated with prosthetic heart valves.
    • The clinical benefit of silver-coated sewing rings in preventing PVE is not yet established.
    • Further research and clinical trials are essential to validate the effectiveness of silver-coated prostheses in reducing PVE rates.
