More precise Aortic Root measure, CTA or TTE?
Test results of a TTE from a year ago show aortic root size as 4.8 cm. Results from a recent CTA show root size at 3.6 cm. Doctor is using the 4.8 cm for my treatment plan. Which test is more accurate?

My cardiac surgeon told me echocardiogram is more accurate
The TEE is the camera placed in your esophagus looking at the back of the heart, and is an echocardiogram. A standard echo is done by passing a transducer over the chest wall and is non invasive. A CTA is read by a radiologist who measures the size of spaces or organs seen.
All of these tests are used by heart specialists.
