Aortic regurgitation can be treated with medication if the symptoms are mild, but if the symptoms are severe, medication is ineffective and heart valve replacement is usually needed to cure the condition. Aortic regurgitation refers to the backflow of blood into the left ventricle due to various causes of aortic valve insufficiency, including aortic atherosclerosis and high blood pressure. In cases where the regurgitation is small, medication can provide temporary relief. Treatment with angiotensin-converting enzyme inhibitors such as captopril and enalapril can be used to reduce the degree of regurgitation while also preventing aortic coarctation. Prolonged aortic regurgitation can lead to increased load on the left side of the heart, which in turn can lead to heart failure. Surgery is usually required to replace the valve, and medication alone is not effective. The medication should be taken under the guidance of a doctor and should not be used without authorization.
