Between 1971 and 1988, cardiac myxoma was identified in 13 (0.003%) of 4000 patients who underwent open-heart surgery at the hôpital du Sacré-Coeur in Montreal. One patient with multiple right atrial tumours also had abnormal cutaneous pigmentation compatible with the recently identified syndrome of "Carney's complex." This syndrome has also been associated with endocrine abnormalities such as primary nodular adrenal hyperplasia, with or without Cushing's syndrome. The authors review the literature and compare the findings with their experience in the surgical treatment of cardiac myxomas.

Cardiac myxomas, the most common primary cardiac tumors, are believed to originate from multipotent mesenchymal cells. Approximately 75% of myxomas occur within the left atrium, increasing the risk of systemic thromboembolic events. While typically benign, atrial myxomas can rarely metastasize to the brain, with fewer than 60 cases reported.

We present a case of a 72-year-old female patient with dyspnea and lipothymia. Echocardiography demonstrates an intracavitary cystic mass that fills almost all left atria causing supravalvular obstruction. The magnetic resonance image revealed a 53 × 47 × 48 mm heterogeneous mass with regular edges, tissue characterization suggested myxoma.
