Beschreibungen/Notizen

• Systemic embolization from a primary cardiac tumor is a relatively frequent presentation. However, an acute myocardial infarction due to coronary embolization is rarely seen. We offer an unusual case of a 50-year-old man who presented with severe angina and was diagnosed with an inferolateral ST-segment-elevation myocardial infarction. Aside from otherwise healthy coronary arteries, his coronary angiogram revealed an acute occlusion of the first obtuse marginal branch, which was treated with balloon angioplasty. Because no residual plaque or dissection was found after the angioplasty, an embolic source was suspected. An echocardiogram then revealed a large mobile left atrial myxoma prolapsing into the left ventricle, so the patient underwent minimally invasive resection. Detailed pathologic examination of the myxoma revealed a concomitant high-grade B-cell lymphoma.
