A rare complication, left ventricular pseudoaneurysm, occurred 24 years after mitral valve replacement. Sudden death was presumed due to pseudoaneurysm rupture, highlighting a severe risk.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Complications
  • Medical Device Complications

Background:

  • Mitral valve replacement (MVR) is a common cardiac surgery procedure.
  • Long-term complications following MVR are infrequent but can be severe.
  • Prosthetic valve dysfunction requires vigilant monitoring.

Observation:

  • A patient developed massive hemorrhage hours post-MVR.
  • Increasing pressure gradient across the prosthesis was noted.
  • Invasive diagnostics identified a left ventricular pseudoaneurysm.

Findings:

  • A left ventricular pseudoaneurysm was diagnosed as a rare complication.
  • The patient experienced sudden death prior to a planned reoperation.
  • Pseudoaneurysm rupture is the presumed cause of mortality.

Implications:

  • This case underscores the potential for delayed, life-threatening complications after MVR.
  • Left ventricular pseudoaneurysms represent a critical surgical risk.
  • Sudden cardiac death can result from undetected prosthetic complications.
