Journal of cardiac failure·2026

A rare case of left ventricular pseudoaneurysm occurred after mitral valve replacement. This condition, presenting as severe heart failure, was successfully treated with a novel surgical technique.

Area of Science:

Cardiology
Cardiac Surgery
Medical Imaging

Background:

Mitral valve replacement is a common procedure for valvular heart disease.
Late complications after valve replacement can be rare but serious.
Pseudoaneurysms are a potential, though infrequent, complication.

Observation:

A 60-year-old woman presented with severe congestive heart failure 4 months post-aortic and mitral valve replacement.
Imaging revealed a large mass, identified as a left ventricular pseudoaneurysm, causing cardiac displacement.
The pseudoaneurysm originated from the left ventricle.

Findings:

The patient had undergone aortic and mitral valve replacement with mechanical prostheses.
Computed tomography of the chest confirmed the diagnosis of a left ventricular pseudoaneurysm.

The pseudoaneurysm's orifice was successfully closed surgically.

Implications:

This case highlights the importance of considering rare complications like pseudoaneurysms after valve surgery.
Successful surgical closure on a beating heart demonstrates a viable treatment option.
Further research into the long-term outcomes of this technique is warranted.
