@jkb5000 I had the same experience. I also went for a CT Calcium score as a baseline as I have normal cholesterol and am very healthy. My calcium score was zero but as an "incidental finding", they noted I had a TAA of 4.2 cm. I am now seeing a cardiologist. I had a stress test and echocardiogram. Both came back normal, with no regurgitation from the valve. The echo measured the TAA at 3.8 cm, but it is normal to have variation from CT to echo. I go back in February for another echo. I have been oddly calm about my diagnosis, which is strange because health issues generally send me into a tailspin. I'm only 57 (female) and have been very active my entire life, with lots of running, weight training, etc. My weight and BMI are normal. My only risk factor is mild familial hypertension, which is controlled by 80 mg of Valsartan. It's a bit of a gut punch to find this out, but at least I know about it and can have it monitored. I have continued to workout as I normally have and will see how it affects the growth of my TAA. I wasn't given any restrictions but I don't lift super heavy weights. I do, however, participate in spin classes and intense hot yoga. I'm curious how my next echo will be. Best of luck to everyone. Knowledge is power! Happy New Year!
