Cardiac myxoma is the most common adult cardiac tumor, with an incidence of 1: 1,000,000 in the general population. Usually occurring between 4-6 decades of life, especially in women, most of the myxomas appear sporadically and are of unknown etiology. Rare cases are genetically determined. Sudden death can occur in 15% of cases. While papillary tumors often complicate coronary or systemic thromboembolism, solid tumors, ovoids, cause heart failure by obstructing the mitral orifice. From a clinical point of view, the atrial myxoma may mimic a valvulopathy, heart failure, dilatation cardiomyopathy, bacterial endocarditis, and may cause heart rhythm disorders, syncope, myocardial infarction and systemic or pulmonary thromboembolism. I will present the case of a giant atrial myxoma, intermittent obstructive of the mitral orifice, evolving towards global heart failure. The lack of severe acute complications during the most likely long-lasting evolution represents an undiscovered curiosity.
