An 86-year-old patient underwent urgent surgery to remove an infected thrombus from a transcatheter aortic valve implantation (TAVI) valve. A biological prosthetic valve was successfully implanted, resolving the infection.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infectious Diseases
Background:
- Transcatheter aortic valve implantation (TAVI) is a common procedure for aortic stenosis.
- Prosthetic valve endocarditis is a rare but serious complication following valve replacement.
- Early detection and intervention are crucial for managing infected prosthetic valves.
Observation:
- An 86-year-old patient presented with symptoms suggestive of prosthetic valve dysfunction.
- Diagnostic tests revealed an infected thrombus on the existing TAVI valve.
- The patient required immediate surgical intervention due to the critical condition.
Findings:
- Urgent surgical exploration confirmed the presence of an infected thrombus on the TAVI valve.
- Successful explantation of the infected valve was performed.
- Implantation of a biological prosthetic valve was completed during the same procedure.
Implications:
- This case highlights the importance of vigilance for prosthetic valve endocarditis in TAVI patients.
- Prompt surgical management can lead to favorable outcomes even in complex cases.
- Biological prosthetic valves may be a suitable option for treating infected TAVI valves.
