Insights
A rare left ventricular myxoma caused acute myocardial infarction due to embolization. Surgical removal of the tumor and embolus, along with bypass grafting, successfully treated the patient.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- Cardiac myxomas are rare primary heart tumors, typically originating in the left atrium.
- Left ventricular myxomas are exceptionally rare and can present with diverse clinical manifestations.
- Embolization from cardiac tumors can lead to significant systemic or coronary artery complications.
Observation:
- A patient presented with symptoms of acute myocardial infarction, a rare presentation for cardiac tumors.
- Diagnostic imaging revealed a mass within the left ventricle consistent with myxoma.
- Coronary angiography demonstrated an embolus occluding the right coronary artery.
Findings:
- Histopathological examination confirmed the diagnosis of left ventricular myxoma.
- The tumor was successfully excised from the left ventricle.
- The tumor embolus was meticulously removed from the right coronary artery, restoring coronary blood flow.
Implications:
- This case highlights the importance of considering rare cardiac tumors in the differential diagnosis of acute myocardial infarction.
- Successful surgical management involving tumor excision, embolus removal, and revascularization is feasible.
- Understanding the embolic potential of cardiac myxomas is crucial for timely diagnosis and intervention.
Abstract:
We report a rare case of left ventricular myxoma with embolization to the right coronary artery, presenting as an acute myocardial infarction. The tumor was excised from the left ventricle, and the tumor embolus was removed from the right coronary artery. Saphenous vein bypass grafting was also performed successfully.
