The mortality rate of acute aortic coarctation is related to the staging. For example, acute aortic coarctation is divided into Debakey type and Stanford type, with Stanford type A having a higher mortality rate of 1% per hour at initial onset, which means that about 25% of patients will die at 24 hours, about 50% at 48 hours, and about 75% at 72 hours. When the disease enters the subacute phase, the mortality rate is approximately 75% after 2 weeks. type B entrapment has a relatively low mortality rate, with a lower mortality rate at 24 hours, approximately 10% within 2 weeks, and a 5-year survival rate of 75% if medical non-surgical treatment is performed.
