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.
