Aortic coarctation very much affects life expectancy because aortic coarctation is a condition of rupture of the inner layer of the blood vessels of the aorta caused by long-term exposure to high blood pressure or unhealthy blood vessels, resulting in the formation of two chambers, true and false, in the middle of the intima and mesentery. Once the aortic coarctation occurs, active treatment is needed because the aortic coarctation is at risk of rupture at any time, and once ruptured, there is no resuscitation measure. Therefore, the patient’s life is very much affected. After the occurrence of aortic coarctation, a CTA examination of the thoracic aorta and abdominal aorta is required. These examinations can clarify the typology, severity and location of the aortic coarctation, and the next treatment plan, whether it is open-heart artificial vessel replacement or descending aortic stenting, can be evaluated from these examinations. The entrapment also affects the blood supply to the organs and may lead to abnormal kidney function.
