Flying with Thoracic Aortic Aneurysm?

I am planning on going to go from Los Angeles, California to Baltimore, Maryland. I have a Thoracic (ascending aorta) Aneurysm of 4.3 cm with a bicuspid aortic valve. I had not considered the fact that there might be a risk of rupture of my ascending aorta and its the last day before my flight. Is there a significant risk of my ascending aorta rupturing due to the high amounts of systolic blood pressure that develops during takeoff/landing of an airplane or not?
