Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.

Pulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. [1] It is a sign of problems with the aorta, including aortic stenosis and aortic regurgitation, as well as hypertrophic cardiomyopathy causing subaortic stenosis.
Just like aortic stenosis, treatment for aortic regurgitation is replacement of the valve after symptoms and left ventricular dysfunction develops. SUMMARY All right, as a quick recap…. Aortic stenosis happens if the aortic valve doesn’t open all the way, and aortic valve regurgitation happens if the valve doesn’t close all the way.
De Musset's sign is a type of rhythmic bobbing of the head in synchrony with the beating of the heart, seen in severe aortic regurgitation. [1]This sign occurs as a result of blood from the aorta regurgitating into the left ventricle due to a defect in the aortic valve.
Abrupt loss of function of the aortic valve results in acute aortic regurgitation (also known as acute aortic insufficiency) and loss in the normal diastolic blood pressure resulting in a wide pulse pressure and bounding pulses. The endocardium perfuses during diastole and so acute aortic regurgitation can reduce perfusion of the heart.
In aortic regurgitation, the aortic valve insufficiency results in the backward flow of blood (regurgitation) that is ejected during systole, and its return to the left ventricle during diastole. This increases the systolic blood pressure, and decreases the diastolic blood pressure, leading to a widened pulse pressure. [9] [3]
Aortic insufficiency, or regurgitation, is characterized by an inability of the valve leaflets to appropriately close at the end systole, thus allowing blood to flow inappropriately backward into the left ventricle. Causes of aortic insufficiency in the majority of cases are unknown, or idiopathic. [6]
