Introduction:
The association of left auricle myxoma and myocardial infarction is exceptional. Nevertheless, a causal relationship exists between the 2 affections.
Observation:
A 54 year-old woman was hospitalised in a rush for myocardial infarction. Sonography revealed a voluminous tumoral formation in the left auricle. The diagnosis of myxoma was confirmed by the anatomopathological examination.
Discussion:
Although systemic embolism represents the most frequent causal link between left auricle myxoma and myocardial infarction, hypercoagulability is another possible cause. This can be explained by the secretion of interleukins 6 and 8 by the myxoma.
