Summary
Post-operative mitral valve replacement can lead to rare left ventricular pseudoaneurysms. Early diagnosis via angiography is crucial due to their high rupture risk.
Area of Science:
- Cardiology
- Cardiac Surgery
- Diagnostic Imaging
Background:
- Mitral valve replacement is a common cardiac procedure.
- Post-operative complications can include cardiac structural abnormalities.
- Left ventricular pseudoaneurysms are rare but serious complications.
Observation:
- Two cases presented with an abnormal protuberance on chest radiographs post-mitral valve replacement.
- The protuberance was located on the left heart border at the "third mogul" site.
- Angiography confirmed left ventricular pseudoaneurysm formation in both cases.
Findings:
- Left ventricular pseudoaneurysms developed post-operatively after mitral valve replacement.
- The location observed is unusual for left ventricular aneurysms, except in specific populations.
- Aetiological factors for these post-operative pseudoaneurysms were considered.
Implications:
- Left ventricular pseudoaneurysms carry a higher risk of rupture than true aneurysms.
- Early diagnosis of these post-operative pseudoaneurysms is essential for patient management.
- This highlights the importance of vigilant surveillance after mitral valve surgery.
