“…To avoid misdiagnosis of cardiac atypical myxoma as a thrombus, we recommend that clinicians perform CCTA to exclude the presence of a mass-feeding artery if necessary. In addition, studies have reported that acquired coronary to left atrial stula occurred in some patients after resection of left atrial myxoma, and the mechanism of this complication may be related to the absence of ligation of cardiac myxoma neovascularization [14,15]. By CCTA reconstruction, we found that one case of cardiac myxoma had two supplying arteries, one from the right coronary artery and the other from the left circumrotatory branch, which was con rmed in the pathologic specimen.…”

Cardiac atypical myxoma usually presents as an isolated mass attached to the atrial septum on imaging, with no movement and a wider attachment base. It is difficult to distinguish it from cardiac thrombus through conventional echocardiography or computed tomography. The purpose of this study is to evaluate the value of coronary computed tomography angiography (CCTA) imaging features in distinguishing cardiac atypical myxoma from cardiac thrombus. This retrospective study included patients with atypical myxoma of the heart confirmed by histopathology (n = 18) and with thrombus disappearance after anticoagulation treatment (n = 23). All patients underwent CCTA examination. There are significant differences in the origin, surface, and enhancement patterns between cardiac myxoma and thrombus groups (p < 0.05, respectively). Specifically, supplied vessels were observed in the cardiac atypical myxoma group, while no neovascularization was detected in the thrombus group (83.33% vs. 0%, p < 0.001). Non-invasive CCTA can distinguish atypical cardiac myxoma and cardiac thrombus through image features, and will play an important role in the diagnosis and follow-up of future cardiac lesions.

“…Suh et al [18] described the case of a myxoma with the formation of an unusual fistula in the left atrial cavity and the development of "intra-atrial steal." Other studies have recommended individual ligation or percutaneous closure with coiling of the neovascularity in cases of myxoma with large feeding branches to relieve patient symptoms [19,20]. In our study, we did not find negative effects of ADN on the clinical manifestations in patients with myxoma.…”

Background: Myxomas are the most common primary cardiac tumors. Angiographically detectable neovascularity (ADN) of myxoma is increasingly being reported as a result of the use of coronary angiography (CAG) to detect coronary artery disease. However, the clinical significance of these findings is not fully understood.Methods: We enrolled 59 patients with cardiac myxoma who also underwent CAG between January 2013 and October 2018. Patients were followed up for a mean of 28.9 months (range 1–69 months). The clinical features, echocardiography measurements, pathological examination findings, CAG results, and outcomes during follow-up were compared between patients with ADN and patients without ADN.Results: ADN was found in 25 patients (42.4%). The arteries feeding the ADN included the right coronary artery(n = 15), the left circumflex coronary artery (n = 7), and both arteries (n = 3). The patients with ADN had a higherproportion of eosinophils (3.2% vs. 2.2%, P = 0.03) and higher low-density lipoprotein cholesterol level (2.7 mmol/L vs.2.2 mmol/L, P = 0.02). Myxoma pedicles were more likely to be located in the interatrial septum in patients with ADN(96% vs. 73.5%, P = 0.02). No significant correlation was observed between the groups in clinical manifestations, atrialarrhythmia, myxoma size, cardiac chamber size, left ventricular ejection fraction, and the prevalence of complicationwith coronary artery disease [16% in the ADN group (n = 4) vs. 20.6% in the non-ADN group (n = 7), P = 0.66].However, patients with ADN tended to have a lower incidence of major adverse cardiac and cerebrovascular events onlong-term follow-up (0% vs. 14.7%, P = 0.07).Conclusion: CAG-detected ADN in patients with cardiac myxoma is associated with a borderline lower rate of major adverse cardiac and cerebrovascular events.

“…CCF usually results from aberrancy in normal embryological development. Trauma, cardiac surgery, or invasive cardiac procedures may also lead to the development of CCF [1], [3], [4]. Diagnosis can be made using coronary angiography, cardiac computed tomography, or echocardiography.…”
