Pathologists need to identify mechanical heart valve prostheses and understand their failure modes. This guide aids in accurate identification and reporting of explanted valves, potentially revealing new failure mechanisms.

Area of Science:

  • Cardiovascular Pathology
  • Biomedical Engineering
  • Medical Device Analysis

Context:

  • Mechanical heart valve prostheses have been utilized since the 1950s.
  • A wide array of prostheses are currently in use and implanted in patients.
  • Explantation of these devices can occur at any time due to various reasons.

Purpose:

  • To provide practicing pathologists with a reference for identifying mechanical heart valve prostheses.
  • To inform about common complications and failure modes associated with these devices.
  • To enhance the accuracy of reports on explanted prosthetic valves.

Summary:

  • This article serves as a guide for identifying mechanical heart valve prostheses and their associated complications.
  • It details important features, common issues, and failure patterns of these cardiac devices.
