The widening of the ascending aorta is curable because once the ascending aorta is widened, it may lead to ascending aortic aneurysm or even aortic coarctation, and the most serious consequence may lead to rupture of the ascending aorta, which may lead to human death. Therefore, in case of widening of the ascending aorta, it is necessary to go to the hospital for cardiac ultrasound. Through the determination of cardiac ultrasound, it is possible to determine the degree of widening of the ascending aorta and the location of the widening, whether it is the widening of the sinotubular junction of the ascending aorta or the widening of the connection between the ascending aorta and the aortic arch, but in either case, surgical treatment is required. The surgical procedure is a prosthetic aortic replacement. After the surgical treatment, it is necessary to take medication for a long time, to check regularly, and to reduce the dose of medication according to the results of the regular review.
