aortic stiffness index
A measure of aortic wall elasticity calculated from the relationship between pressure change and relative diameter change.
aortopulmonary window
Congenital heart defect characterized by abnormal communication between the ascending aorta and pulmonary artery.
aortotomy
Surgical incision into the aortic wall, typically performed for access during cardiac or aortic procedures.

bicuspid aortic valve
A congenital malformation where the aortic valve has two leaflets instead of the normal three.

coarctation of the aorta
A congenital narrowing of the aorta, typically near the ductus arteriosus insertion site.
commissural fusion
Abnormal joining of aortic valve leaflet commissures, typically seen in congenital aortic stenosis.
Crawford classification
A system for categorizing thoracoabdominal aortic aneurysms based on anatomical extent and organ involvement.

The distance from the aortic annulus to the free edge of the aortic valve cusp at the point of commissural attachment, c...
David procedure
A valve-sparing aortic root replacement technique that preserves the native aortic valve.
DeBakey classification
A system for categorizing aortic dissections based on the anatomical extent and involvement of the ascending aorta.

A two-stage surgical technique for extensive thoracoabdominal aortic aneurysm repair involving staged reconstruction.
endoleak
Persistent blood flow into the aneurysm sac after endovascular repair, classified by location and mechanism.
EVAR
Endovascular aneurysm repair using stent-grafts to exclude aneurysms from circulation.

An endovascular technique using custom grafts with openings to preserve blood flow to visceral arteries during aneurysm...
frozen elephant trunk
A hybrid technique combining open arch replacement with antegrade stent-graft deployment into the descending aorta.
hemiarch replacement
A surgical procedure involving replacement of the ascending aorta and partial aortic arch, typically including the lesse...
