Systolic Expansion of the Atrium

Systolic expansion (systolic expansion) of the atria is one of the signs of atriogastric valve insufficiency. This symptom appears on a radiograph as an expansion of the X-ray shadow of the atria during ventricular systole.

The mechanism of development of systolic dilatation of the atria is associated with the return of blood to the atria through a defect in the atrioventricular valves. As a result, excess pressure is created in the atria, which leads to an expansion of their shadow on the x-ray.

Systolic enlargement of the atria can be caused by various reasons, such as heart defects, infectious diseases, cardiomyopathies and other diseases. It is important to note that this symptom is not an independent disease, but only indicates the presence of other heart problems.

If systolic expansion of the atria is detected, it is necessary to conduct an additional examination to determine the cause of this symptom and prescribe appropriate treatment. In some cases, surgery may be required to correct the atrioventricular valve defect.

Systolic expansion of the atria is the expansion of the X-ray shadow of the left atrium at the time of systole (contraction) of the ventricles of the heart. This phenomenon occurs when blood returns to the atrium through a defect in the atrioventricular valve. Systolic dilatation of the atria is one of the signs of atrioventricular valve insufficiency.

When the ventricles contract, they push blood into the atria, which in turn fill with blood. However, if there is a defect in the atrioventricular valve, blood may flow back into the atrium during ventricular systole. This leads to expansion of the X-ray shadow of the atria and the appearance of systolic expansion.

Systolic expansion can be a sign of various heart diseases, such as mitral stenosis, mitral valve regurgitation, tricuspid regurgitation, and other diseases.

If you have symptoms associated with atrial systolic enlargement, you should see your doctor for diagnosis and treatment. In some cases, surgery may be required to correct a defect in the atrioventricular valve.
