Quick Answer

Full Answer

Mild enlargement of the aorta may not have any symptoms at all, as stated by UW Health. A doctor may detect the condition during other exams or tests. However, any level of enlargement may lead to leakage of blood to the heart due to weaker aortic valves, which can cause rapid heart pulse and shortness of breath. Severe enlargement of the aorta can increase the weakness of the aortic wall, possibly causing the bulge to dissect.

Patients suffering from Marfan syndrome are usually advised to always watch out for any signs of aorta enlargement. The treatment depends on its severity and the rate of growth. Surgery may be required to fix the bulge if it is large. Using computer tomography scans and ultrasounds may help a doctor to know the size of the aortic aneurysm. If the bulge tears, it can lead to life threatening conditions, as stated by WebMD.
