When the pressure in the left ventricle rises above the pressure in the aorta, the aortic valve opens, allowing blood to exit the left ventricle into the aorta (the oxygen rich blood which comes from the lungs). When ventricular systole ends, pressure in the left ventricle rapidly drops (the relaxation or the filling phase of the heart)
So the aortic valve is essentially the barrier between body and heart, which is why it is so important.. Basically, there are two typical processes that can affect the aortic valve and one congenital condition that will affect it.

Its frequency increases with age, making it a major geriatric problem. Of adults aged > 65 years, 21-29% exhibit aortic valve sclerosis
Aortic valves affected by aortic sclerosis contain a higher amount of oxidized LDL cholesterol and show increased expression of metalloproteinases. Clinically, it can be suspected in the presence of soft ejection systolic murmur at the aortic area, normal split of the second heart sound, and normal volume carotid pulse, but it can be best detected by echocardiography

The left ventricle pumps oxygenated blood to the body. It connects to the aorta, the main blood vessel leading to the body
These valves help the blood flow through the heart’s four chambers and out to the body.. The aortic valve normally has three small parts, called leaflets

Aortic Valve: Function, Location & Anatomy [5]

– Left ventricle, the heart chamber that pumps blood from your heart to the rest of your body.. – Aorta, the artery that carries blood away from your heart.
Semilunar valves get their name from the crescent moon shape of the flaps that make up the valve.. Typically, hearts have a left atrium and a right atrium.
Between each chamber, valves open and close to help blood flow in the right direction. Each valve has small flaps called leaflets that open and close each time your heart beats.

Predicting Outcomes in Patients With a Trileaflet Aortic Valve and Dilated Aorta [8]

Predicting Outcomes in Patients With a Trileaflet Aortic Valve and Dilated Aorta. In patients with a dilated proximal ascending aorta and a trileaflet aortic valve, what are the factors associated with adverse outcomes and what is the incremental prognostic utility of indexing aortic root (for ascending aorta) to the patient’s height?
Patients were included if: 1) a dilated (≥4 cm) aortic root and/or ascending aorta was identified on an initial transthoracic echocardiogram, and 2) either a contrast-enhanced computed tomographic angiogram or a contrast-enhanced magnetic resonance angiogram confirmed the measurements from echocardiography. Surgical procedures and time to surgery were recorded
Over a median follow-up of 7.3 ± 2.6 years, there were a total of 130 deaths with no patients lost to follow-up. The proportion of deaths was significantly higher in the group with aortic root area/height ratio ≥10 cm2/m versus those <10 cm2/m (33% vs

Aortic Valve Anatomy: Overview, Gross Anatomy, Microscopic Anatomy [9]

The normal human heart contains 4 valves that regulate blood flow into and out of the heart. The aortic and pulmonic valves are known as the semilunar valves, whereas the tricuspid and mitral valves are referred to as the atrioventricular valves
Cardiac valves are surrounded by fibrous tissue forming partial or complete valvular rings, or annuli. These annuli join the fibrous skeleton of the heart to anchor and support the valvular structures.
Relative to the aorta, the mitral valve is located posterior and to the left, the tricuspid valve is located inferiorly and to the right, and both valves abut on the posteroinferior margins of the aortic root, albeit with the atrioventricular separating structures interposing between the root and the tricuspid valve. In most cases, the orifices of the coronary arteries arise within the 2 anterior sinuses of Valsalva, usually positioned just below the sinotubular junction

Repair of trileaflet aortic valve prolapse: mid-term outcome in patients with normal aortic root morphology ☆ [10]

Bruno Chiappini and others, Repair of trileaflet aortic valve prolapse: mid-term outcome in patients with normal aortic root morphology, Interactive CardioVascular and Thoracic Surgery, Volume 6, Issue 1, February 2007, Pages 56–59, https://doi.org/10.1510/icvts.2006.140848. We described our mid-term results in repairing prolapsing aortic cusps in 21 patients with aortic regurgitation and normal aortic root morphology
Prolapse involved the left cusp in four patients (19%), the right cusp in 10 patients (47%) and the non-coronary cusp in 7 (33%) patients. Correction of the prolapsing cusp was achieved by either free edge plication, triangular resection or resuspension with polytetrafluoroethylene sutures, frequently associated to a subcommissural annuloplasty
Mean clinical follow-up was 27.2±17.1 months (range: 10–72 months). At follow-up transthoracic echocardiography, fourteen patients (73%) were free from aortic regurgitation and five patients (26%) had mild aortic regurgitation without clinical signs of congestive heart failure

Bicuspid Aortic Valve [11]

A bicuspid aortic valve is a congenital heart defect that affects the one-way valve between your heart and your aorta, known as the aortic valve. Normally, your aortic valve has three cusps that regulate blood flow from your heart to your aorta
Your aortic valve cusps, also called leaflets or flaps, open and shut to regulate blood flow between your heart and your aorta. These flaps make sure your oxygen-rich blood flows in the right direction: Out of your heart and into your aorta
The flaps should open widely to let blood flow out of your heart and then close securely.. If you only have two flaps, rather than three, it’s harder for your aortic valve to function in the right way

Aortic valve replacement – Why it’s done [12]

An aortic valve replacement is used to treat conditions affecting the aortic valve. – aortic stenosis – where the valve is narrowed, restricting blood flow
These problems can be something you’re born with or can develop later in life.. – senile aortic calcification – where calcium deposits form on the valve as you get older, preventing it opening and closing properly
– underlying conditions that can damage the aortic valve – including Marfan syndrome, Ehlers-Danlos syndrome, rheumatic fever, lupus, giant cell arteritis and endocarditis. If you have aortic valve disease, you may not experience any symptoms at first.

Techniques in trileaflet aortic valve repair [13]

Throughout the last 20 years, significant progress in the field of aortic valve (AV) repair resulted in techniques that are achievable and now widely accepted (1) as treatment options for patients with aortic insufficiency (AI). These advances include deep understanding of the functional anatomy of the AV and pathophysiological mechanisms of AI; the development of surgical techniques to restore normal geometry to the aortic root while sparing the AV; and the maturation of the concept of functional aortic annulus (FAA) (2) as an echocardiographic and surgical concept
Our group accumulated a significant experience with AV repair techniques, over the last 20 years, and continuously refined our strategies and systematic approaches to treat different types of AV regurgitation. In this article we describe the current strategies and techniques used in our institution’s systematic approach of the regurgitant trileaflet AV.
The FAA (Figure 1) is the natural stent containing the AV, and that is formed by the combination of the following three structures: the aortic annulus, defined as the hinge point of the AV leaflets, the sinuses of Valsalva and the sinotubular junction (STJ) (3). This structure forms a three-dimensional cylinder where the proximal plane consists of the aortic annulus, also known as the ventriculo-aortic junction (VAJ), and the distal plane consists of the STJ

This causes an effective increase in afterload, left ventricular hypertrophy and, eventually, symptoms of congestive heart failure. The classic triad of symptoms from aortic stenosis are angina, syncope and dyspnea
No medical therapy exists to halt or reverse the disease process, and aortic valve replacement (AVR) is the ultimate treatment.. The most common cause of aortic stenosis in a person over age 70 years is calcification of a normal trileaflet aortic valve; this process is sometimes referred to as “senile degeneration.” No medical therapy has been shown to delay the valve degeneration

They are most often congenital while an acquired bicuspid valve occurs when there is fibrous fusion between the right and left cusps of a pre-existing trileaflet aortic valve.. A congenitial biscuspid aortic valve is considered to be one of the most common causes of isolated aortic stenosis 4
The estimated incidence of a congenital bicuspid valve in the general population is thought to be ~2%. dilatation of the proximal ascending aorta: most frequent association 9

Bicuspid Aortic Valve [16]

Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only 2 small parts (leaflets), instead of the normal 3
In some cases, a person can have 3 leaflets but 2 leaflets become fused together over time. This is a condition called functional bicuspid valve

Problem: Aortic Valve Regurgitation [18]

Aortic regurgitation is leakage of blood through the aortic valve each time the left ventricle relaxes.. A leaking (or regurgitant) aortic valve allows blood to flow in two directions
The heart will have to do more work to compensate for the blood leak back into the left ventricle. The walls of the ventricle sometimes thicken (hypertrophy), and a thickened heart muscle is a less effective pump
What are the symptoms of aortic valve regurgitation?. Mild aortic regurgitation may produce few symptoms.

Aortic valve [19]

This article needs additional citations for verification. The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta
The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets.[1] The aortic valve is the last structure in the heart the blood travels through before stopping the flow through the systemic circulation.. The aortic valve normally has three cusps however there is some discrepancy in their naming.[2] They may be called the left coronary, right coronary and non-coronary cusp.[2] Some sources also advocate they be named as a left, right and posterior cusp.[3][4] Anatomists have traditionally named them the left posterior (origin of left coronary), anterior (origin of the right coronary) and right posterior.[2]
In two of these cusps, the origin of the coronary arteries are found. The width of the sinuses in cross-section is wider than the left ventricular outflow tract as well as wider than the ascending aorta

Aortic stenosis may be caused by rheumatic disease, a congenital bicuspid valve or calcification of a trileaflet valve. In Europe and North America, the aetiology of aortic stenosis most often is increased leaflet stiffness, without commissural fusion, caused by lipo-calcific deposits on the aortic side of the valve leaflets
Aortic valve sclerosis and stenosis are the most common valve diseases in Europe and North America, with sclerosis present in about 25% of all people over age 65 years and stenosis present in 2–7% of this population.1 Significant outflow obstruction tends to occur at a younger age in patients with a bicuspid valve, possibly related to increased mechanical stress on the valve leaflets.. At the tissue level, aortic valve stenosis is characterised by focal areas of displacement of the subendothelial elastic lamina on the aortic side of the leaflet; there is protein and lipoprotein deposition and an inflammatory cell infiltrate with macrophages, T lymphocytes, and production of proteins, such as osteopontin, that are associated with tissue calcification

What Is Aortic Valve Stenosis? [21]

Every day, about 2,000 gallons of blood circulate through your heart. You have four valves in your heart to help control all that blood flow
One of the most common and most serious valve problems is called aortic valve stenosis.. Stenosis can mean that the leaflets or cusps of your valve have thickened or scarred and don’t open as well as they should
Over time, the heart has to work harder to pump enough blood out to all your. Your heart has four valves that open and close in a steady rhythm to circulate blood through your body when they are working right.

Heart valve disease [22]

Tests are used to diagnose a heart condition or to see how healthy your heart is. Find out what to expect from some of the most common tests.
Your heart valves control the direction of your blood flow. They have very small flaps of skin called leaflets (sometimes called cusps) that open and close like doors with every heartbeat
The blood delivers oxygen and nutrients to all parts of your body to help your organs and muscles work properly.. Heart valve disease is when one or more of your heart valves don’t work like they should.

The Bicuspid Aortic Valve [23]

Bicuspid aortic valve (BAV) represents the most common cardiac congenital malformation in the adult age, with strong male predominance. It may occur in isolation, or in association with other congenital heart diseases
It may be associated with abnormalities of the aortic wall such as coarctation of the aorta, aortic dissection, and aortic aneurysm. Most patients with a BAV develop some complications during life [1,2].
BAV has been identified at a prevalence of 4.6 cas-es per 1000 live births. The prevalence of BAV according to sex has been found to be 7.1 cases per 1000 among male neonates, and 1.9 per 1000 among female neonates.

Bicuspid Aortic Valve [24]

A bicuspid aortic valve has two leaflets, instead of three.. The aortic valve sits at the top of the heart where the blood exits to travel to the brain and body
In some individuals, the valve is malformed from birth, and two of the leaflets are fused together (bicuspid, or two leaflets total). This congenital heart valve disorder affects both the aortic valve and the aorta, the great vessel attached to the aortic valve.
The valve can become stenotic, meaning it is thickened and calcified, obstructing the blood flow out of the heart. The valve can also be insufficient, meaning it allows blood to leak back into the heart because the leaflets do not perfectly meet
