AoA
Aortic annulus diameter
- PLAX (zoomed AV).
- Mid-systole (ECG: The beginning of T wave).
- Measure at insertion point of right and non-coronary.
- Method: Inner edge to inner edge
AoSV
Aortic sinuses of valsalva diameter
- PLAX (zoomed AV).
- End-diastole (ECG: R wave).
- The sinus of Valsalva should be measured at the maximum curvature of the right and non-coronary aortic sinuses.
- Method: Leading edge to leading edge
AoSTJ
Aortic sinotubular junction diameter
- PLAX (zoomed AV).
- End-diastole (ECG: R wave)
- The Sinotubular junction is measured where the curvature of the sinus transitions to the straight walls of the ascending aorta.
- Method: Leading edge to leading edge
AoPxA
Proximal ascending aorta diameter
- PLAX (zoomed AV).
- End-diastole (ECG: R wave)
- Measured 1-2cm form sinotubular junction.
- Method: Leading edge to leading edge
AoArch
Aortic arch diameter
- SSN window (aortic arch).
- End-diastole (ECG: R wave)
- Measured before truncus brachiocephalicus.
AoDesc
Descending aorta diameter
- SC window (long axis abdominal aorta)
- Others possible views:
- End-diastole (ECG: R wave)
