Hello, I m a 32 year old female with mosaic Turner Syndrome, post menopausal, on HRT. My recent echocardiogram showed an aortic root diameter of 3.1 cm with a tricuspid aortic valve, along with a mildly dilated left ventricle and left atrium. Is this serious? Does it require surgery? Will this condition get worse with time? My BMI is generally between 18 and 19, I used to run a lot but do more gentle exercise these days along with a lot of walking. I am an ex smoker, now vape and I occasionally consume alcohol. Thank you for your help and kind regards, Renata Berczy
