Hi pearjas - your situation sounds like mine. I'm currently at 45mm (sometimes 45 , sometimes 46 or 47) been like this since I discovered it back in 2009. I take 300mg of Irbesartan per day (since January. Was on atenolol before) Irbesartan is similar to losartan.. Apparently the trick is to have the highest dose, I.e 300mg. Like you, this is in my mind on a daily basis and I am currently thinking about some decisions I need to make which includes:
1. PEARS procedure. This is a procedure developed here in the UK by Tal Golsworthy an engineer who 'fixed his own heart'. He is Marfan. The problem with this procedure that it's not been fully tested in bicuspids and I don't think it's been tested in Ehlers. The added issue with bicuspid is because of the valve! The procedure makes complete sense to me! Wrap the aorta and hopefully no more enlargement. For me the what if issue is whether my bicuspid valve will leak more on the future? However, get in touch with Tal. Honestly he is extremely good and a very nice chap. I am in the process of talking about this procedure more with one of the surgeons (Conal).
2. Wait till it reaches 5.0! And cross that bridge when I get there. My cardiologist did say that sometimes, the aorta stops dilating and especially with the Irbesartan, it's proving some great results! ... Who knows!
The issues around the above for me are:
1. I am scared shi * about surgery; and
2. I am scared shi * living like this!
So like you, I got no idea what to do! My cardiologist thinks I should wait and see. No real restrictions apart from usual heavy weights etc.... But I understand, these "what if?" questions eat me alive.
P.s I am 32.
