What do you mean by a small amount of mitral regurgitation?

A small amount of tricuspid regurgitation refers to the regurgitation of blood from the right ventricle back to the right atrium during systole, and a small amount of blood from the left ventricle back to the left atrium.

Under normal circumstances, when the heart contracts, the mitral valve and tricuspid valve are closed to prevent blood regurgitation in the right ventricle and left ventricle. However, due to abnormal structure and function of the mitral valve and tricuspid valve, damage or relaxation, it may cause blood regurgitation during systole. However, the amount of blood regurgitation at this time is small, and the patient generally has no obvious performance. Symptoms such as shortness of breath and asthma may occur during physical labor.
