aortic stiffness index
A measure of aortic wall elasticity calculated from the relationship between pressure change and relative diameter change.
aortic remodeling procedure
A valve-sparing surgical technique that involves replacing the aortic root while preserving the native valve within the...
aortic root abscess
Localized collection of infected material within the aortic root structures, typically associated with infective endocar...
aortic root dilatation
Enlargement of the aortic root structures including the sinuses of Valsalva, often requiring surgical intervention.
aortic root geometry
The three-dimensional anatomical configuration of the aortic root including annulus, sinuses, and sinotubular junction r...
aortic root replacement
Surgical procedure replacing the entire aortic root, including the valve, sinuses of Valsalva, and ascending aorta.
aortic stent graft migration
Displacement of an endovascular aortic stent graft from its original deployment position. May result in loss of seal and...
aortic stiffness index
A measure of aortic wall elasticity calculated from the relationship between pressure change and relative diameter chang...
aortic uncrossable lesion
An aortic pathology that cannot be traversed with standard endovascular equipment. Typically refers to completely occlud...
aortic valve area
The effective cross-sectional area of the aortic valve opening, measured to assess severity of aortic stenosis.
aortic valve commissurotomy
Surgical procedure involving division of fused commissures in a stenotic aortic valve to improve valve opening.
aortic valve cusp plication
A valve-sparing surgical technique involving the folding and suturing of redundant aortic valve cusp tissue. Used to cor...
aortic valve dimensionless index
Ratio of aortic valve area to left ventricular outflow tract area, used to assess aortic stenosis severity independently...
aortic valve effective orifice area
The functional cross-sectional area available for blood flow through the aortic valve during systole. Key parameter for...
aortic valve gradient
The pressure difference across the aortic valve during systole, measured by echocardiography or catheterization.
aortic valve neocuspidization
Surgical technique creating new aortic valve leaflets using pericardial tissue or synthetic materials.
aortic valve reimplantation
A valve-sparing procedure where the native aortic valve is excised with a rim of surrounding tissue and reimplanted into...
aortic valve-sparing surgery
Surgical procedure preserving the native aortic valve while replacing the diseased aortic root.
aortic wall calcification
Calcium deposition within the aortic wall layers, typically indicating advanced atherosclerotic disease. Complicates sur...
aortic wall shear stress
The tangential force per unit area exerted by blood flow on the aortic wall surface.
aortic wall tension
The circumferential force acting on the aortic wall per unit width of the vessel.
aortitis
Inflammatory disease of the aortic wall, which can lead to aneurysm formation, stenosis, or dissection.
aortobifemoral bypass
A surgical procedure creating a graft conduit from the aorta to both femoral arteries to bypass aortoiliac occlusive dis...
aortoenteric fistula
Abnormal communication between the aorta and bowel, typically occurring as a late complication of aortic graft surgery.
aortoplasty
Surgical repair or reconstruction of the aorta to restore normal vessel geometry and function.
