[Myocardial infarction in a young woman with left atrial myxoma]
Insights
A rare case of cardiac myxoma causing myocardial infarction in a young woman without risk factors is presented. Surgical removal of the left atrial myxoma resolved symptoms, highlighting the importance of considering rare causes for heart attacks.
Area of Science:
- Cardiology
- Oncology
Background:
- Acute myocardial infarction (AMI) typically occurs in patients with coronary artery disease.
- Cardiac myxomas are rare primary heart tumors, usually benign, and rarely associated with AMI.
Observation:
- A 38-year-old female patient without traditional coronary risk factors presented with AMI.
- Echocardiography and cardiac catheterization revealed a left atrial mass and normal coronary arteries.
- Surgical resection of the mass confirmed it as a myxoma.
Findings:
- The patient recovered fully with no recurrence of tumor or symptoms three months post-surgery.
- Pathological examination confirmed the diagnosis of cardiac myxoma.
Implications:
- This case underscores that cardiac myxoma can be an unusual cause of myocardial infarction, even in young individuals without risk factors.
- Early diagnosis and surgical management of cardiac myxoma are crucial for favorable outcomes.
- Further research into the mechanisms linking cardiac myxoma to coronary events is warranted.
Abstract:
A 38 year old female patient without coronary risk factors suffered an acute myocardial infarction. Echocardiographic and cardiac catheterization was undertaken and a left atrial mass with normal coronary arteries was assessed. The tumor mass was successfully resected and pathological examination of the specimen disclosed a myxoma. Three months after the operation the patient is symptom-free and an echocardiogram taken at this time showed no evidence of tumor. A bibliographic review of the association cardiac myxoma and coronary artery occlusion or myocardial infarction is done.
