Bilateral cardiac myxomas and peripheral myxomas in a patient with recent myocardial infarction
Insights
A young man with myocardial infarction had coronary arteriography revealing aneurysms and abnormal vessels supplying tumors. Histologic examination confirmed these tumors were myxomas, with two additional myxomas found elsewhere.
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Coronary arteriography is a key diagnostic tool for evaluating coronary artery disease.
- Myocardial infarction in young adults warrants thorough investigation into underlying causes.
- Cardiac myxomas are rare primary tumors of the heart, often associated with systemic syndromes.
Observation:
- Coronary arteriography in a 29-year-old male post-anterior wall myocardial infarction revealed distal left coronary artery aneurysms.
- Abnormal vascular clusters supplied tumors located in the right ventricle and left atrium.
- No major coronary artery obstructions were identified.
Findings:
- Operative and histologic examination confirmed the cardiac tumors as myxomas.
- Two additional myxomas, located outside the heart, were also histologically proven.
- The findings suggest a potential link between coronary artery abnormalities and disseminated myxomas.
Implications:
- This case highlights the importance of considering cardiac myxomas in young patients presenting with myocardial infarction and unusual coronary findings.
- Disseminated myxomas may present with diverse clinical manifestations, including cardiovascular compromise.
- Further research may elucidate the relationship between cardiac myxomas and vascular anomalies.
Abstract:
Coronary arteriography, performed for recent anterior wall myocardial infarction in a 29 year old man, showed multiple aneurysms of the distal branches of the left coronary artery without evidence of obstructions in the major branches, and two clusters of abnormal vessels, supplying tumors in the right ventricle and the left atrium. At operation and histologic examination both tumors appeared to be myxomas. In addition, two myxomas, located elswhere in the body, could be proven histologically.
