Aortic coarctation type 1 is primarily treated surgically, and there are no definitive data on its surgical survival rate, but the 10-year freedom from reoperation rate after surgery is about 60% to 80%. Surgical survival for aortic coarctation type 1 is related to the site of surgical management, with a 10-year freedom from reoperation rate of about 80% if only partial aortic arch replacement is performed, and about 60% for the descending aorta, but this varies from person to person. Aortic coarctation type 1 is a condition where the coarctation originates in the ascending aorta and then tears and expands beyond the aortic arch to the descending aorta or even the abdominal aorta, requiring surgery. The prognosis is worse than other types of aortic coarctation because of the rapid onset of symptoms. If left untreated, the mortality rate within 48 hours can be as high as 50%, so prompt medical attention is recommended.
