aortic root geometry
The three-dimensional anatomical configuration of the aortic root including annulus, sinuses, and sinotubular junction relationships.
Full Definition
Aortic root geometry encompasses the complex three-dimensional relationships between the aortic annulus, sinuses of Valsalva, sinotubular junction, and coronary ostia. Proper understanding of this geometry is essential for valve-sparing procedures, as distortion of normal relationships can lead to valve dysfunction. Key measurements include annular dimensions, sinus diameters, sinotubular junction diameter, and effective height of the leaflets.
Usage
Usage note: Encompasses functional relationships, not just static measurements.
