Insights
A rare left atrial myxoma caused a patient's myocardial infarction through coronary embolization. Surgical removal confirmed the tumor as the likely cause, highlighting its potential for serious cardiac events.
Area of Science:
- Cardiology
- Pathology
- Oncology
Background:
- A 66-year-old male presented with symptoms of acute inferior wall myocardial infarction.
- Previous cardiac investigations revealed a left atrial tumor, with normal coronary arteriography.
- The patient had experienced myocardial infarction 55 days prior to this admission.
Abstract:
A 66-year-old male patient had an acute inferior wall myocardial infarction 55 days prior to the admission to the hospital. Echocardiogram and cardiac catheterization disclosed a tumor of the left atrium and the coronary arteriography was normal. The tumor was surgically removed and pathological examination revealed it to be a myxoma. In the absence of other etiologic possibilities, left atrial myxoma was considered the main hypothesis with the development of thrombi and coronary embolization.
