Hello,
Congratulations on being a new mom -- that is great news. I can understand your concerns. It sounds like the doctors want to evaluate the rate of progression over the next months before making a decision about surgery. If the waiting makes your uncomfortable, you should mention that to your doctors and see if they would be willing to reevaluate sooner, like 3 months. Six months is probably not unreasonble.
It is important to follow your symptoms and make sure that they are not worsening. It is also important to understand more about the aortic stenosis (bicuspid, membrane, etc). Bicuspid AVs are more likely to develop ascending aneurysms.
The key is communication with your doctor and making sure you trust them. Never be afraid to seek a second opinion -- that is your right as a patient.
I hope this helps. Thanks for posting.
If you do progress to the surgical threshold, be aware that the surgery for this condition has progressed and while still risky, it's much better than 10-20 years ago. You want a surgeon who has done hundreds of these operations and has a proven track record. You'll generally get that by going to a major center, e.g. Cleveland Clinic, Stanford, etc.
In my case, I recovered from the surgery well and was back to doing the things I wanted to and was back at work in about 8 weeks. Today, I get monitored yearly and so far have had no ill effects. I take a beta blocker daily, and am fully active. While there may be complications in your case, most people are able to resume their normal activities on about the same schedule as I did. Good luck.
Since you are such a young'un with an aneurysm and known aortic stenosis, there is a good chance you have a bicuspid aortic valve. About 1-2% of the population is born with a BAV and an inordinately large number of those have ascending aortic aneurysms. It is most typical for BAV's to have aneurysms mid-ascending on the aorta rather than at the root, which is more typical of Marfan Syndrome. (Note: "typical" not "always")
There are a couple of excellent websites I would recommend you visit. The first is very informative, run by medical people, and I suspect you'll recognize yourself in the descriptions of BAVD: http://www.bicuspidfoundation.com/About_Us.html
The second is an online community of people whose lives have been touched in one way or another by valvular heart disease. This site is purely for support and they will welcome you warmly and help you get through this difficult time in your life. There are literally hundreds of people there who have been where you are (or their family member has). It's www.valvereplacement.com
All the best to you.
