Breast cancer tumor embolism in the LCx causes fatal massive MI and cardiac rupture.
Why the study?
Tumor embolism of the coronary artery causing myocardial infarction and cardiac rupture is a rare clinical event requiring detailed case description.
Case Report (n=1)
This case report describes a rare instance of fatal myocardial infarction and cardiac rupture caused by a coronary tumor embolism from breast cancer.

Tumor embolism warrants consideration in cancer-associated MI; extends sparse Level 5 reports but leaves open need for systematic study.
A case of tumor embolism of the coronary artery in a 78-year-old woman was presented. The tumor embolus originating from cancer of the breast resulted in massive large myocardial infarction in the lateral wall of the left ventricle, and she died of cardiac rupture. Metastatic lesions were found in the bilateral lungs, the endocardial and subendocardial layers of the left ventricle, with a growth of tumor thrombus into the left atrium, and also other extracardiac organs.

Hiraoka et al. (1976) conducted a case report in Tumor embolism of the coronary artery (n=1). Tumor embolism from breast cancer was evaluated on Death due to cardiac rupture. A 78-year-old woman with breast cancer died from cardiac rupture secondary to a massive myocardial infarction caused by a tumor embolism in the left circumflex coronary artery.
