Insights
Left atrial myxoma can cause acute myocardial infarction. Surgical removal of the tumor and coronary artery bypass grafting during the acute phase of myocardial infarction is recommended for life-threatening cases.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Left atrial myxoma is a rare primary cardiac tumor.
- Acute myocardial infarction (AMI) is a critical cardiovascular event.
Observation:
- A patient presented with left atrial myxoma concurrently with acute myocardial infarction.
- Hemodynamic compromise persisted despite intra-aortic balloon pump support.
Findings:
- The patient underwent successful tumor resection and coronary artery bypass grafting (CABG) to the right coronary artery on day five post-infarction.
- This combined surgical approach was performed during the acute phase of myocardial infarction.
Implications:
- Early surgical intervention for myxoma causing AMI may be life-saving.
- Combined myxoma removal and CABG is a viable strategy in acute settings.
- This case highlights the importance of considering myxoma in patients with unexplained myocardial infarction.
Abstract:
We describe a patient with left atrial myxoma associated with acute myocardial infarction. Since hemodynamics were impaired even with the support of an intra-aortic balloon pump, the patient underwent removal of the tumor concomitant with coronary artery bypass grafting to the right coronary artery on the fifth day from infarction onset. In circumstances of life-threatening of myxoma associated with acute myocardial infarction, removal of myxoma with coronary artery bypass should be performed in an acute phase of myocardial infarction.
