Heart tumors can be benign (myxoma, lipoma, fibroma, etc.) and malignant (angiosarcoma, fibrosarcoma, mesothelioma, thymoma, etc.), have intracavitary and intramural growth. Miksoma LP with unidimensional EchoGD is characterized by the presence of bulky dense education behind the mitral membrane diastole time and in the left atrium during systole .; tight formation of a layered character between the cusps of the mitral valve in diastole (during tumor prolapse). Echocardiography in B-mode allows you to identify echo signals from the volume of education, coming from the interatrial septum in the cavity of the left atrium and to assess the size, mobility and degree of obstruction of the cavity.
LP mix classification : Type 1 small prolapse myxoma. These mobile left atrial myxomas prolapse into the mitral valve during diastole, without disrupting the movement of the valve. The diastolic signal cloud between the mitral valve cusps in this case is the only indicator for one-dimensional echocardiography. Type 2 is a small non-spinning myxoma. These myxomas are more difficult to differentiate echocardiographically, since they do not interfere with mitral valve movements. Two-dimensional echocardiography in this case demonstrates a small beam of signals closer to the interatrial septum. 3 type-large prolapse myxomas. Two-dimensional echocardiography reveals multiple left-atrial signals that enter the left ventricle during diastole and cause a disruption of valve movement in diastole. 4 type-large non-prolabile myxomas,in which two-dimensional echocardiography reveals a large minimally mobile mass filling the left atrium and obturating the lumen of the mitral valve during diastoles.
