Discussion
Cardiac myxomas are most frequently detected as incidental findings being prevalently asymptomatic. Clinical manifestations greatly depend on the anatomic location and the size of mass. Whenever myxomas reach significant dimensions they may lead to obstructive manifestation, which are commonly mistaken for valvular stenosis. In fact, in our patient, complete obliteration of the mitral valve orifice lead to dyspnea, orthopnoea and syncope, mimicking mitral valve stenosis. Intracardiac masses responsible for hemodynamic compromise are not a frequent finding; emergent surgery is the gold-standard treatment and, upon mass excision, immediate hemodynamic improvement is observed. Furthermore, both clinical improvement and symptomatology relief are immediately detected.
