Giant left ventricular aneurysm after recurrent mitral valve replacement.

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Medical Case Reports

Background:

• Mitral valve replacement (MVR) is a common cardiac procedure.
• Complications like left ventricular pseudoaneurysm are documented post-MVR.
• True aneurysms post-redo MVR remain exceptionally rare in medical literature.

Observation:

• A patient underwent a third mitral valve surgery.
• Following the procedure, the patient developed a true left ventricular aneurysm.
• The patient also presented with atrioventricular complete block.

Findings:

• This case represents the first reported instance of a true left ventricular aneurysm after redo mitral valve replacement.
• The patient required and received a DDD pacemaker for the atrioventricular complete block.
• Despite the diagnosis, the patient opted against surgical aneurysmectomy.

Implications:

• This case highlights a previously undocumented complication of complex mitral valve surgery.
• It underscores the importance of vigilant monitoring for rare cardiac events post-redo procedures.
• Further research may be warranted to understand the pathogenesis and optimal management of such aneurysms.
