“…On the other hand, the non-visualization of coronary occlusion by cardiac angiography does not rule out the possibility of myxoma emboli in the coronary circulation, as it occurred in 40% of the 19 cases reported in the last 10 years. This finding would be a result of the response to fibrinolytic therapy or spontaneous degradation of emboli with a major gelatinous stromal component [ 5 ].…”

The differential diagnosis of myocardial infarction in patients with a number of potential causes can be challenging, especially when there is no angiographic evidence of coronary obstruction. We describe a case of extensive anterior ST-elevation myocardial infarction in a young male smoker who had a left atrial myxoma and a history of cocaine use 10 hours before the event. Clinical reasoning during a myocardial infarction investigation should be oriented by the probability of the causal relationship between the ischemic event and each factor present in the clinical context.

“…The emboli more likely to degrade are those with a high proportion of gelatinous stroma and low cell density. 27 Panos et al 28 reviewed 26 cases of left atrial myxoma presenting with acute myocardial infarction. The myocardial involvement was 63.9% inferior, 22.7% anterior, and 9.1% posterior.…”

Left Ventricular Myxoma Causing Sudden Death

Sudden cardiac death due to a myxoma is rarely reported in the literature. Cardiac myxomas are benign tumors of the heart, most frequently located in the left atrium. Left ventricular myxomas are rare. Left ventricular myxomas attached to the anterior papillary muscle are especially rare, with only 1 case being reported in the literature. Myxomas have the potential to cause embolization, obstruction, or arrhythmia. We report a case of a 32-year-old man who sustained sudden death and was found to have a left ventricular myxoma attached to the anterior papillary muscle at autopsy. Although the subject also had evidence of a distant myocardial infarction and dilated cardiomyopathy, the myxoma was apparently clinically silent. Cardiac myxomas may be treated by surgical excision with excellent prognosis. However, they can remain silent and undiagnosed and, hence, have the potential for causing sudden cardiac death. In addition to the case report, we present a literature review of these issues involving cardiac myxomas.

“…From our review of the literature, we found two reported cases of combined left circumflex (LCX) artery and left anterior descending (LAD) artery embolism from an atrial myxoma causing myocardial infarction (MI) [4, 5], one case affecting both LCX and diagonal branches of the LAD artery [6] and only three cases affecting the LCX artery alone [7–9]. …”

“…It is well documented that tumor emboli have malignant potential [6, 23–25], with the ability to persist [9], invade, and even grow inside the coronary artery. Conversely, there are cases of left atrial myxoma presenting as acute MI but with normal coronary arteries.…”

Myocardial infarction from coronary artery embolism is a very rare but potentially lethal sequel of left atrial myxoma. Most atrial myxomas causing myocardial infarction are diagnosed retrospectively after a 2D echocardiogram is performed for assessment of myocardial function after a myocardial infarction. We present a relatively healthy 53-year-old male with anterolateral wall myocardial infarction and 100% occlusion at the proximal part of the obtuse marginal branch of the circumflex coronary artery that was subsequently reperfused. A 2D echocardiogram performed two days later revealed a left atrial mass, which was successfully resected and proven to be a myxoma. No recurrence of the tumor was seen on follow-up after four months. An automatic implantable cardioverter defibrillator was placed for residual ischemic cardiomyopathy with clinical improvement.
