Abstract
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 higher proportion 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, atrial arrhythmia, myxoma size, cardiac chamber size, left ventricular ejection fraction, and the prevalence of complication with 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 on long-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.

Abstract
A 59-year-old woman with episodes of chest pain was diagnosed with cardiac myxoma. Transesophageal echocardiography (TEE) showed a massive vascularized tumor and there was a blood stream spurting from the internal cavity of tumor into left atrium through an interconnected sinus tract. Coronary artery angiography (CAG) indicated that the mass was enhanced upon the administration of contrast media, which spouted into the cardiac chamber. This is the first case to report the development of the coronary artery steal syndrome due to hemorrhage and associated fistula formation in a left atrial myxoma, which was detected by TEE and confirmed by CAG.
