A rare cardiac myxoma was found on a mechanical mitral valve annulus in a 74-year-old woman. Surgical removal was successful, confirming this unusual presentation of cardiac myxoma.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- A 74-year-old female patient presented with an intracardiac tumor.
- The patient had a history of a mechanical valve replacement in the mitral position six years prior.
Observation:
- Transesophageal echocardiography identified a mobile, hypoechogenic mass on the anterior annulus of the mechanical mitral valve prosthesis.
Findings:
- The intracardiac mass was surgically excised.
- Pathological and clinical evaluations confirmed the diagnosis of cardiac myxoma.
- This represents the first reported case of myxoma on a mechanical valve annulus.
Implications:
- Highlights the possibility of cardiac myxoma formation on prosthetic material.
- Underscores the importance of thorough diagnostic evaluation for intracardiac masses.
- Informs surgical and management strategies for rare cardiac tumor presentations.
