dilated aortic root arrhythmia treatment

I have been diagnosed with dilated aortic root arrhythmia. My regular physician is sending me to cardiologist but I am curious about what the treatment is. I do not have high blood pressure and it is dilated to 4.2. I am 45 years old - non smoker.

Generally, an aortic root greater than 4.0 cm is consdiered an aneurysm, and if the aneursym is growing (>5.0 cm) surgery begins to be considered to prevent a possible rupture.  

Treatment is to control blood pressure and no heavy lifting or isometric exercise.  Do you have a bicuspid aorta valve?

Not sure if I have a biscupid. The Ct is being done next week. I saw the cardiologist today and it is strange to him that my bllod pressure is not elevated.
