Aortic insufficiency
Aortic Insufficiency
Aortic insufficiency (AI), also known as aortic regurgitation (AR), is a condition where the aortic valve does not close tightly, causing the blood to flow backward into the left ventricle of the heart.
Pronunciation
Aortic insufficiency: /eɪˈɔːr.tɪk ˌɪn.səˈfɪʃ.ən.si/
Etymology
The term "aortic" is derived from the Greek word "aortē", meaning 'the great artery', and "insufficiency" comes from the Latin "insufficientia", meaning 'inadequacy' or 'deficiency'.
Symptoms
Symptoms of aortic insufficiency may include fatigue, shortness of breath, heart palpitations, and chest pain.
Causes
Aortic insufficiency can be caused by several conditions, including congenital heart defects, endocarditis, rheumatic heart disease, and aortic dissection.
Diagnosis
Diagnosis of aortic insufficiency typically involves a physical examination, echocardiogram, and possibly a cardiac catheterization.
Treatment
Treatment for aortic insufficiency may include medication, lifestyle changes, and in severe cases, surgery to repair or replace the aortic valve.
