Several years ago I had an ascending aortic aneurysm repaired, and my bicuspid aortic valve replaced. At the time, the surgeon told me he thought the aneurysm was caused by turbulence from the valve. However, since then I've also read that aneurysms can be caused by congenital connective tissue disorders linked to bicuspid aortic valves. How do you determine the cause of an aneurysm? If it is related to a connective tissue disorder, is it important to be screened for aneurysms elsewhere in the body, and how would that be done? Thank you, ticktockgal
