Summary

A Bjork-Shiley mitral valve prosthesis disk embolized during ablation, lodging in the aorta. Emergency valve replacement was successful, with the embolized disk left in situ without complications.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Biomedical Engineering

Background:

  • Bjork-Shiley mitral valve prostheses are mechanical heart valves used to replace diseased mitral valves.
  • Transeptal ablation is a procedure used to treat certain heart rhythm disorders.

Observation:

  • A case of disk embolization occurred during a transeptal atrioventricular junction ablation procedure.
  • The embolized disk originated from a Bjork-Shiley mitral valve prosthesis.

Findings:

  • The dislodged disk migrated and lodged in the lower thoracic aorta.
  • The patient underwent successful emergency valve replacement surgery.
  • The embolized disk was intentionally left in place without causing further complications.

Implications:

  • This case highlights a rare but serious complication associated with mechanical heart valves during cardiac procedures.
  • It underscores the importance of careful patient selection and procedural monitoring in patients with prosthetic valves.
  • The successful management demonstrates the feasibility of conservative management for certain embolized prosthetic components.
