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.
Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve insufficiency causes regurgitation through that valve, called aortic regurgitation, and the terms aortic insufficiency and aortic regurgitation are so closely linked as ...
Aortic regurgitation. Aortic insufficiency (AI) is a condition in which the aortic valve fails to close completely at the end of systolic ejection, causing leakage of blood back through the valve during LV diastole. The constant backflow of blood through the leaky aortic valve implies that there is no true phase of isovolumic relaxation.
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.
Well normally, right after the ventricle pumps blood out through the aortic valve, the valve shuts and remains shut until the ventricle fills again. With aortic regurgitation, or sometimes called aortic insufficiency, blood flows back from the aorta into the left ventricle during diastole, or during ventricular filling.
The endocardium perfuses during diastole and so acute aortic regurgitation can reduce perfusion of the heart. Consequently, heart failure and pulmonary edema can develop. Slowly worsening aortic insufficiency results in a chronic aortic regurgitation which permits the heart to compensate (unlike acute aortic regurgitataion). This compensation ...
