Hey- Im new to this site, but I am a 22 year old male that has been having a lot of left side chest pain, shortness of breath, and congestion lately, especially if I am laying on my left side. My echo showed that I have moderate left ventricular hypertrophy, moderate aortic valve regurgitation, and an ascending aorta diameter of 4.0cm. My uncle (blood uncle) recently had an aortic arch aneurysm repair for an aortic arch diameter of 6.2cm. I read that with family history, problems are more likely to occur earlier in life if you do have dilation or an aneurysm, but I was wondering if anyone had any ideas if having a 4.0cm diameter at 22 years old is a bad thing/ something I have to really watch, or if it isn't really a big deal? Thanks in advance.
