Summary
A rare case of prosthetic mitral valve leaflet escape occurred, leading to aortic embolization and patient death. This highlights the critical need for prompt diagnosis and intervention in acute prosthetic valve dysfunction.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
Background:
- Acute prosthetic valve dysfunction presents a significant mortality risk.
- Mitral valve replacement is a common procedure, but complications can arise.
Observation:
- A 24-year-old male presented with acute left ventricular failure four months post-mitral valve replacement with a TRI bileaflet valve.
- Echocardiography revealed massive mitral insufficiency, indicative of a stuck valve.
Findings:
- Emergency surgery identified a stuck open cranial leaflet; the caudal leaflet was absent.
- The TRI valve was replaced, and the embolized leaflet was retrieved from the aorta.
- The patient succumbed to sepsis from aspiration pneumonia.
Implications:
- This is the first reported instance of leaflet escape and aortic embolization with the TRI bileaflet rotatable mitral valve.
- Prompt identification and surgical intervention are crucial for managing acute prosthetic valve dysfunction.
