2D versus 3D

Transesophageal echocardiographic 3D guided 2D measurements versus plain 2D measurements of aortic valve annulus and ascending aorta

Timeline :
During every cardiac surgery, transesophageal echocardiography is performed / used, both with two dimensional and three dimensional imaging. The images will be recorded and stored for off line analysis. The aortic valve annulus as well as the diameter of the ascending aorta will be measured in two dimensional and three dimensional ultrasound images, which will be compared to measurements on NMR images taken before the cardiac surgery.
Hypothesis :
measurements on the three dimensional echocardiographic images are more precise than measurements on two dimensional echocardiographic images
There will be less variance in values on three dimensional ultrasound images .
