A small amount of tricuspid regurgitation means that normal blood is passing from the right atrium through the tricuspid valve to the right ventricle. If tricuspid regurgitation is present, it means that some of the blood from the right ventricle is regurgitating from the tricuspid valve into the right atrium. If there is a small amount of tricuspid regurgitation, it is not a cause for concern. This small amount of regurgitation is negligible and will not have any effect on health or on the structure and function of the heart. If the regurgitation is moderate or above, or even if it is severe, it is important to look at what is causing such a large regurgitation in the tricuspid valve. For example, congenital heart disease with a left-to-right shunt, which leads to an enlarged right heart, can aggravate tricuspid regurgitation in clinical practice. For example, in older adults with pulmonary heart disease, moderate or greater tricuspid regurgitation can also occur. For example, if pulmonary hypertension develops later in life, a small amount of tricuspid regurgitation can also occur. Therefore, if mild tricuspid regurgitation is present, there is nothing to worry about. If the regurgitation is moderate or severe, it is recommended to visit a specialist cardiology clinic as soon as possible.
