Bicuspid Aortic Valve and dilated ascending aorta

Hi, I have recently been diagnosed with a Bicuspid Aortic Valve with mild regurgitation through a stress echo and a dilated ascending aorta through a ct with contrast.  I am scheduled to have a repeat in 1 year to look for changes.

After reading the information from the Cleveland Clinic, I have a few questions.

1.  My CT with contrast gave the following measurements.

                                              Ascending               Descending
Proximal Thoracic Aorta            3.8 x 3.7                  2.1 x 2.3
Mid  Aorta                                3.3 x 3.5                  2.1 x 2.2
Distal Aorta                              3.2 x 3.4                  2.0 x 2.0

So by Cleveland standards, my ascending aorta would be considered an aneurysm because it is 1.5 times that of the adjacent aorta.  Is this correct?

2.  I've been also trying to calculate at what point I would want to have surgery if it is ever needed.  You have a calculation for that about it being under 10.  When I take my largest point 3.8, and my height 5'  4 3/4 " and use your formula I come up with 8.8.  If I do it at 4.1 and my height I am past the 10 point.  So would I have the surgery that early?  I know it is usually 5 or above.

Thank you
