It involves replacement of the aortic root without replacement of the aortic valve.

Other vascular abnormalities include aortic root and annulus dilatation.

Starting in infancy, her aortic root dilated rapidly to a diameter of 4.5 cm at age 6 yr.

The two coronary arteries of the heart arise from the aortic root, just above the cusps of the aortic valve.

Another mechanism is that the dissection may extend into the aortic root and detach the aortic valve leaflets.

A good fluoroscopic view is essential, whereby an exact perpendicular angle to the aortic root is considered to be optimal for the implantation.

Dilatation of the aortic root - (cause of death in 75 - 85%)

Enlarged aorta (dilation of the aortic root).

The portion of the aorta that is connected to the heart is called the aortic root.

Usually echocardiography is used to take measurements of the aortic root as well as transesophageal echocardiography.
