VEGA, Julián et al. Large mitral annulus myxoma presenting with syncope: Report of one case. Rev. méd. Chile [online]. 2016, vol.144, n.12, pp.1617-1620. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872016001200015.

We report a 23-year-old woman, with three recent exertional syncopes. Transthoracic (TTE) and transesophageal (TEE) echocardiography found a large heterogeneous mass (38 x 35 mm) arising from the posterior mitral annulus, protruding in systole through the left ventricular outflow tract (LVOT). Heart MRI confirmed the echocardiography findings, suggesting a cardiac myxoma. Cardiac surgery accomplished the complete resection of the lesion, confirming a mass arising from the posterior mitral annulus and preserving mitral anatomy and function. Pathology was positive for a myxoma. Uneventful evolution allowed the discharge of the patient at the fifth postoperative day. Control TTE discarded any complication.
