Heart valve

heart valvesvalvesatrioventricular valves
The aortic valve is a valve in the human heart between the left ventricle and the aorta.
The two semilunar (SL) valves, the aortic valve and the pulmonary valve, which are in the arteries leaving the heart.

Heart

cardiachuman heartapex of the heart
The aortic valve is a valve in the human heart between the left ventricle and the aorta.
The semilunar aortic valve is at the base of the aorta and also is not attached to papillary muscles.

Aorta

aorticaortic archaortic root
The aortic valve is a valve in the human heart between the left ventricle and the aorta.
The ascending aorta begins at the opening of the aortic valve in the left ventricle of the heart.

Bicuspid aortic valve

bicuspid valvecongenitally have two leaflets
The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets.
Bicuspid aortic valve (BAV) is an inherited form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet valve (bicuspid valve) instead of the normal three-leaflet valve (tricuspid).

Ventricle (heart)

ventricleleft ventricleright ventricle
The aortic valve is a valve in the human heart between the left ventricle and the aorta.
The left ventricle receives oxygenated blood from the left atrium via the mitral valve and pumps it through the aorta via the aortic valve, into the systemic circulation.

Aortic insufficiency

aortic regurgitationaortic valve insufficiencyaortic
Common causes of aortic regurgitation include vasodilation of the aorta, previous rheumatic fever, infection such as infective endocarditis, degeneration of the aortic valve, and Marfan's syndrome.
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 sinus

sinus of Valsalvaaortic sinusesSinus of Morgagni (aorta)
The three cusps, when the valve is closed, contain a sinus called an aortic sinus or sinus of Valsalva.
An aortic sinus is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.

Pulmonary valve

pulmonic valvepulmonarypulmonary (or pulmonic) valve
It is one of the two semilunar valves of the heart, the other being the pulmonary valve.
Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery.

Percutaneous aortic valve replacement

transcatheter aortic valve replacementtranscatheter aortic valve implantationpercutaneious transapical TAVI
Traditionally, this has been a surgical procedure (surgical AVR or SAVR) but a non-surgical option called transcatheter aortic valve replacement (TAVR) delivers a prosthetic valve through a catheter.
Percutaneous aortic valve replacement (PAVR), also known as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR), is the replacement of the aortic valve of the heart through the blood vessels (as opposed to valve replacement by open heart surgery).

Bentall procedure

Bentall's procedurecomposite aortic valve graft
The Bentall procedure is a type of surgical procedure when the aortic valve, aortic root, and ascending aorta are replaced in a single operation.
A Bentall procedure is a cardiac surgery operation involving composite graft replacement of the aortic valve, aortic root and ascending aorta, with re-implantation of the coronary arteries into the graft.

Systole

systolicsystolic pressureventricular systole
When the left ventricle contracts (systole), pressure rises in the left ventricle.
The contractions generate intra-ventricular pressure, which is increased until it exceeds the external, residual pressures in the adjacent trunks of both the pulmonary artery and the aorta; this stage, in turn, causes the pulmonary and aortic valves to open.

Ross procedure

Another procedure for aortic valve replacement is the Ross procedure (after Donald Ross) or pulmonary autograft.
The Ross procedure (or pulmonary autograft) is a cardiac surgery operation where a diseased aortic valve is replaced with the person's own pulmonary valve.

Artificial heart valve

prosthetic heart valveartificial heart valvesmechanical heart valve
There are two basic types of artificial heart valve: mechanical and tissue.
The human heart contains four valves: tricuspid valve, pulmonic valve, mitral valve and aortic valve.

Turner syndrome

45,Xmonosomy XTurner
Turner syndrome, a congenital condition that affects females, can often have a bicuspid aortic valve as one of its symptoms.
The higher rate in the group of pure 45,X monosomy is primarily due to a difference in the rate of aortic valve abnormalities and coarctation of the aorta, the two most common cardiovascular malformations.

Heart sounds

It contributes the A2 component to the second heart sound and changes with inspiration ("splitting") Transthoracic echocardiography (TTE) is used as the first test because it is non-invasive.
Second heart sound caused by semilunar valves – Aortic (A) and Pulmonary/Pulmonic (P).]]

Stroke

strokesischemic strokecerebrovascular accident
Mechanical valves are made of metal and have evolved over time ("ball and cage", "bileaflet"). Mechanical valves require lifelong anticoagulation to avoid forming blood clots on the valves that can lead to embolism often resulting in stroke. These tend to be favored in younger individuals as they typically last longer than tissue valves. The shape of these valves do not mimic normal heart valves.
High risk: atrial fibrillation and paroxysmal atrial fibrillation, rheumatic disease of the mitral or aortic valve disease, artificial heart valves, known cardiac thrombus of the atrium or ventricle, sick sinus syndrome, sustained atrial flutter, recent myocardial infarction, chronic myocardial infarction together with ejection fraction

Mitral valve

The heart has four valves and the other two are the mitral and the tricuspid valves.

Tricuspid valve

The heart has four valves and the other two are the mitral and the tricuspid valves.

Transposition of the great vessels

transposition of the great arteriestransposition of great vesselsransposition of the great arteries
The congenital disease, transposition of the great arteries, these two valves are reversed (the anterior valve is the aortic valve) and the origin of the coronaries still follows this "rule" that the origins are in the sinuses facing the pulmonary valve.

Pressure

When the left ventricle contracts (systole), pressure rises in the left ventricle.

Blood

human bloodhematologicalblood-forming
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.

Vasodilation
