What does mild subvalvular aortic regurgitation mean?

Minor aortic valve regurgitation, also known as trace aortic regurgitation, generally refers to the backflow of blood from the aortic valve into the left ventricle. The details are as follows:

During the diastolic phase of the heart, blood from the aorta flows back into the left ventricle through an incompletely closed aortic valve. On color Doppler echocardiography, a retrograde blood flow signal can be observed at the aortic valve during diastole. Major underlying conditions associated with this phenomenon include coronary atherosclerotic heart disease, rheumatic heart disease, infective endocarditis, degenerative changes of the aortic valve, aortic dissection, and hypertension. Based on the extent of regurgitation observed on echocardiography, aortic regurgitation can be classified as mild, moderate, or severe. Patients with trace aortic regurgitation typically remain asymptomatic and usually do not require specific treatment; however, regular follow-up monitoring is recommended.

Patients are advised to seek timely medical attention if they experience any discomfort and to receive standardized treatment under the guidance of a physician, which may facilitate recovery.
