The absolute majority (89.6%) of the primary heart tumors (PPS) are myxoma of the heart (MS). These intracavitary tumors can be localized in any heart chamber. In most cases (88.7%), they are localized in the left atrium (LP) and are most often detected in the atrial fibrillation (MPP) in the oval fossa of the short leg on a narrow or broad base, which allows the tumor to remain mobile during its growth.
Macroscopically, the myxoma of the heart resembles a polyp or grape cluster, gelatinous, mild or dense, with a smooth texture. The frequent absence of a capsule creates favorable conditions for possible fragmentation (separation of sites) of neoplasms during cardiac contractions and subsequent embolism of arterial vessels.
Along with such clinical manifestations as heart failure, heart rhythm disturbances, dizziness and loss of consciousness, embolism of arterial vessels in the absence of obvious causes may suggest the presence of a source of embolism precisely in the cavity of the heart.
In recent years, due to the widespread introduction of echocardiography, CT and MRI, the number of patients with heart tumors has significantly increased. Important conditions for the successful treatment of this difficult contingent of patients are the timeliness and accuracy of the diagnosis of the disease with an extremely polymorphic clinical picture, the urgency of surgical treatment, subject to certain conditions conducting an operation aimed at its radical.
