“…To the best of our knowledge, there are only five studies in the literature investigating the relationship between CAD and myxoma [8, 9, 13, 14, 15] (table 4). Most of those studies showed prevalence rates of CAD in myxoma patients of 0–11%, and only the study performed by Fueredi et al [9]yielded a very high (6/9, 66.7%) rate.…”

“…Balk et al [17]reported chronic coronary embolization of myxoma led to vessel narrowing and aneurysm dilatation, which was similar to the findings of cerebral, renal, and pulmonary vessels. Acute myocardial infarction might result from coronary embolization [15, 18, 19, 20, 21]. Besides, Isobe et al [22]reported that 3 myxoma patients had elevated levels of interleukin-6 and interleukin-8, which would induce a hypercoagulable state and induce coronary thromboembolism.…”

Cardiac myxoma is the most common form of primary heart tumor and often treated with surgical resection without a preoperative angiographic examination for fear of potential risk of sudden death. During the last 14 years, 24 of 38 patients with myxoma underwent coronary angiography. Coronary artery disease (CAD) and other abnormalities were found in 5. Our findings indicated that CAD is not uncommon among the myxoma patients, and coronary angiography should be performed preoperatively in all cases.

“…Eight cases have been reported in which myocardial infarction of the inferior wall was the clinical manifestation which led to the discovery and the operation of myxoma during the patient's lifetime (Table I). [1][2][3][4][5][6][7][8] Preoperatively injured coronary artery responsible for AMI was proved to be recanalized postoperatively in four reports. There was no clear statement regarding this point in the remaining four reports.…”

We describe a patient with left atrial myxoma associated with acute myocardial infarction. Since hemodynamics were impaired even with the support of an intra-aortic balloon pump, the patient underwent removal of the tumor concomitant with coronary artery bypass grafting to the right coronary artery on the fifth day from infarction onset. In circumstances of life-threatening of myxoma associated with acute myocardial infarction, removal of myxoma with coronary artery bypass should be performed in an acute phase of myocardial infarction.

“…Concomitant coronary artery bypass grafting with excision of the myxoma was performed in only 8 cases. Some cases of complete and spontaneous recanalization of the affected coronary artery have been reported [12][13][14] and the rate of recanalization caused by necrolysis, spontaneous lysis, or fragmentation may be high for coronary embolism resulting from a myxoma.…”

Left atrial myxoma associated with acute myocardial infarction and multiple cerebral infarctions: Report of a case

2010

View full text Add to dashboard Cite

We report a case of left atrial myxoma associated with acute myocardial infarction (AMI) in a 63-year-old man. Percutaneous coronary intervention was performed immediately, and we removed white intracoronary particles by using a thrombectomy catheter. The postinterventional course was uneventful; however, on hospital day 5, pathological examination revealed platelet thrombus and myxomatous tissue from the particles aspirated by thrombectomy catheter, and transesophageal echocardiography showed a gelatinous mass in the left atrium. Based on these findings, we diagnosed AMI caused by coronary embolization from a left atrial myxoma, and excision of the myxoma was scheduled. However, preoperative magnetic resonance imaging revealed multiple subacute cerebral infarctions, and the tumor was successfully excised on hospital day 13. Although coronary embolization induced by cardiac myxoma is rare, it should be considered in a young to middle-aged patient presenting with signs of AMI without coronary risk factors.
