	Aortic insufficiency - Wikipedia, the free encyclopedia
		Aortic insufficiency (AI), also known as aortic regurgitation (AR), 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.
		Aortic insufficiency can be due to abnormalities of either the aortic valve or the aortic root (the beginning of the aorta).
		Aortic insufficiency can be treated either medically or surgically, depending on the acuteness of presentation, the symptoms and signs associated with the disease process, and the degree of left ventricular dysfunction.

	Aortic dissection - Wikipedia, the free encyclopedia
		While many patients with an aortic dissection have a history of hypertension, the blood pressure is quite variable at presentation with acute aortic dissection, and tends to be higher in individuals with a distal dissection.
		Aortic insufficiency (AI) occurs in 1/2 to 2/3 of ascending aortic dissections, and the murmur of aortic insufficiency is audible in about 32% of proximal dissections.
		Because aortic dissection may present to the emergency room physician similar to a myocardial infarction, the physician must be careful to make the proper diagnosis prior to initiating treatment for myocardial infarction, since the treatment regimen for myocardial infarction can be lethal to an individual presenting with aortic dissection.

	Lifespan's A - Z Health Information Library - Aortic insufficiency (Site not responding. Last check: 2007-11-01)
		Aortic insufficiency is a heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly.
		In the past, rheumatic fever was the primary cause of aortic insufficiency.
		Aortic insufficiency caused by other conditions often cannot be prevented but some of the complications can be.

	Aortic Valve Insufficiency \| AHealthyMe.com
		The aortic valve separates the left ventricle of the heart (the heart's largest pumping chamber) from the aorta, the large artery that carries oxygen-rich blood out of the left ventricle to the rest of the body.
		Aortic valve insufficiency occurs when this valve cannot properly close after blood that is leaving the heart's left ventricle enters the aorta.
		Aortic valve insufficiency is also know as aortic valve regurgitation because of the abnormal reversed flow of blood leaking through the poorly functioning valve.

	Aortic Insufficiency
		This is a condition in which the aortic valve has become disfigured to such an extent that its leaflets no longer are able to completely oppose each other during diastole (see figures 48a, 48b, 48c, 48d).
		Aortic valve regurgitation can be caused by infection of the aortic valve due to syphilis via unprotected coitus, (figure 205 immediately below) and bacteria, which have gained access to the blood stream and the aortic valve through the use of illicit drugs intravenously.
		Aortic valve prolapse occurs in 2 % of patients with mitral valve prolapse(MVP).The primary form of MVP may occur in families,where it appears to be inherited as an autosomal dominant trait with varying penetrance.

	Aortic Valve Repair for Aortic Insufficiency
		The decision to repair an aortic valve is made by weighing the risk of repair failure versus the benefit of avoidance of oral anticoagulation therapy.
		This type of AR is caused by a dilated aortic annulus resulting in a sagging of the belly of the cusp resulting in lack of central cusp apposition.
		Aortic valve repair has been described in the literature predominantly for the indications of dilated annulus, bicuspid aortic valve (BAV) and cusp prolapse of trileaflet valves [1, 5, 7].

	COLOR FLOW IMAGING OF VALVULAR REGURGITATION - Aortic Insufficiency
		In Figure 4.29 an aortic regurgitant jet is directed toward the anterior mitral valve leaflet, then reflected off to the left in a patient with a low-pitched diastolic rumbling murmur suggestive of mitral stenosis.
		Even though the degree of aortic insufficiency was small, the direction of the jet readily explained the origin of the murmur, as it was likely that the regurgitant jet set the mitral valve into rapid vibrations.
		In Figure 4.30 there is a parasternal long-axis view from a 30-year-old patient who had had mild fevers and two positive blood cultures several months prior to admission with a large and markedly turbulent aortic insufficiency jet direct toward the apex of the left ventricle along the posterior aspect of the interventricular septum.

		The goals of surgery in children with chronic aortic insufficiency are to prevent irreversible left ventricular dysfunction and to provide for long-term survival.
		The increasing utilization of the Ross procedure to treat chronic aortic insufficiency has led to new interest in the question of when to operate on a regurgitant aortic valve.

		Aortic insufficiency (AI) is frequently the result of the repair of aortic stenosis, (whther surgically or by balloon dilatation), and is due to fibrosis, thickening, and contracture of the valve leaflets.
		The insufficiency increases preload, which then increases LV stroke volume.
		AI also increases myocardial oxygen consumption, since the myocardial blood flow occurs during diastole and the aortic valve is insufficient the blood flow through the coronaries is reduced.

		Background: Aortic valve insufficiency (AI) results from leakage and backflow of blood that is ejected from the left ventricle (LV) into the ascending aorta back into the left ventricle.
		The aortic valve is composed of 3 thin leaflets (ie, cusps) that project from the wall of the proximal ascending aorta.
		In recent years, the percentage of individuals with AI caused by aortic root disease has been steadily increasing compared with the percentage of those with valvular disease.

		I was reading the last letter BBQ's cardiologist sent to his pediatrician and it said he has mild aortic insufficiency.
		Hi Teresa, yes aortic insufficiency is basically when the aortic valve doesn't close or function properly and allows some of the blood that passes through it back into the heart (this is what they mean when they say the valve leaks).
		I know of children who can have an aortic insufficiency that stays mild for years and doesn't become a problem at all and others like Jamie who's become an issue.
