Welcome to JustAnswer and thank you for your question. I do not agree with this general info by dr love which does not give any recommended guidelines by AHA and ESC.
I your case you need to evaluate how severe is your aortic regurgitation.
If it is severe then you need medicine like beta blockers and ACIi to slow the progress of the aortic dilation.
Echo after every 1 year is recommended.
light exercise like walking a dog and walking on flat ground is recommended more severe exercises are harmful. Other simple way to assess type of exercise you can do is to not to exceed your speed more than 4-5km/h.
Controlling blood pressure and keeping it less than 140/90 is recommended.
Salt intake of less than 2.5 grams per day.
If you also have family history of marfans, ehlers danlos then you need surveillance of you family as well with help of echocardiogram.
Beta blockers and ACEi are medicine which have proven role to slow the progress of dilation.
Any symptoms of dizziness, blackouts, cold hand and feet, low blood pressure, severe chest or abdominal pain should be treated as emergency visit as these symptoms indicate an emergency in people with dilated aorta.
I hope this helps.
