Right atrial hypertrophy occurs as a result of compensatory enlargement of the right atrium because of the greater load it is subjected to.
There are several reasons for right atrial enlargement:
1. Atrial septal defect, the blood from the left atrium will flow to the right atrium in the direction of pressure, which in the long run will lead to an increase in the loading capacity of the right atrium, so the right atrium will be enlarged;
2. Tricuspid stenosis, because the tricuspid valve is the valve through which blood from the right atrium flows to the right ventricle, and if it is narrowed, the blood from the right atrium will not be able to flow to the right ventricle. This will increase the load on the right atrium and over time the right atrium will hypertrophy.
3. Pulmonary arterial hypertension, pulmonary arterial hypertension, the right ventricle of the inflow of blood into the pulmonary artery will reduce the amount of blood, resulting in an increase in the right ventricle, the right ventricle will be compensatory enlargement, when the right ventricle can not be increased to accommodate more blood, from the right atrium to the right ventricle will reduce the flow of blood in the right ventricle, accumulation in the right atrium, and in the end, the right atrium will be hypertrophic.
If the examination finds that the right atrium has the phenomenon of hypertrophy, should complete the relevant examination, find out the cause of the disease and actively cooperate with the doctor’s treatment.
