Echo 2013 normal. 2015 "mild thickening" aortic valve. (also just treated for bacteremia/meningitis) cause for valve change in 2 years? i'm only 42!

Picture says a lot: I would need to compare the 2013 and 2015 images to answer better. But there is a threshold at which point a valve is considered thickened and in the past 2 years its possible the valve thickness passed the threshold from normal to thickened. The cause of valve thickening is multifactorial- genetics, cholesterol, inflammation, hypertension, diet, lipoprotein a levels, lack of plant foods etc

Ans: The bacteria will often attack the heart valves. Sounds like this is what happened to you when you became ill now good news is may not get any worse. So why was the echo done to begin with? Did you have some heart symptoms or short of breathe? Just take good care of yourself and try to have a healthy lifestyle
