Mild aortic regurgitation is usually asymptomatic, and some patients may occasionally have symptoms such as chest tightness and palpitations, and diastolic murmurs can be heard on auscultation on examination, but they are relatively rare. Aortic regurgitation refers to diastolic regurgitation of blood from the aorta back to the left ventricle, which admits filling blood flow from the left atrium, increasing the load. If the regurgitation is simple and mild, such as physiologic regurgitation, there are usually no clinical symptoms. When patients are found to have mild regurgitation in the aortic valve, no special treatment is needed. It is recommended to have regular ultrasound examinations and review once in 0.5-1 year, choosing the same hospital and the same doctor to reduce review errors, and to observe the flow and degree of regurgitation during the review so that the professional doctor can judge the specific situation and make the next intervention.
