Cardiac myxoma + symptoms?

summary

Cardiac myxoma is the most common true tumor in the heart cavity. It is generally considered to be benign, with some complex manifestations and malignant tendency, but some people think it is a true tumor with lower malignant degree. So, cardiac myxoma + symptoms? Let's talk about it

Cardiac myxoma + symptoms?

Multiple myxomas have different effects on blood flow according to different cardiac cavity, tumor number, tumor size and range of motion. Those who occupy both left and right cardiac cavities are more complicated, and the overall performance is the synthesis of each cardiac cavity.

There were more adhesions, more severe obstruction and less activity in right cardiac myxoma. In the diastolic phase of the right atrium, the tricuspid valve orifice may be blocked and (or) the valve leaflet may be affected, so the sign of tricuspid stenosis or stenosis with regurgitation is presented. If the tumor is close to the orifice of the vena cava or the middle part of the right atrium and enlarges to the orifice of the vena cava, it will block the vena cava and cause the corresponding congestive reactions, such as hepatomegaly and edema of the lower limbs.

When the left atrial myxoma is located in the left atrium, it moves to the mitral valve orifice in diastole, and then dislodges into the left ventricle through the valve orifice, and retracts into the left atrium in systole. Therefore, the left atrial myxoma blocks the mitral valve orifice in diastole, which is similar to the true mitral stenosis, resulting in different degrees of pulmonary congestion and some of the most common symptoms (97% palpitation, 96% shortness of breath) and signs (diastolic murmur), Clinically, it is similar to rheumatic mitral stenosis. However, the degree of pulmonary congestion is generally mild, which is often out of proportion to the more severe symptoms and signs. If the tumor is too large to return to the left atrium during systole and is stuck at the valve orifice (syncope, sudden death), or a part of the tumor is attached to the mitral annulus or leaflet, blocking mitral valve activity and affecting its closure, mitral regurgitation may occur. This can be manifested as mitral stenosis and regurgitation and double phase murmur.

matters needing attention

If you have long-term dyspnea, severe anemia and fever, there is a great chance that it is caused by cardiac myxoma. For the sake of your own health, it is recommended that patients go to the hospital for examination as soon as possible.
