What’s the prognosis (outlook) for people with ascending aortic aneurysms?

Studies show that 79% of people who have elective (non-emergency) surgery for ATAAs survive for at least 10 years after treatment. But the outlook is much worse if an aneurysm dissects or ruptures. About half of these people don’t survive if they don’t have emergency surgery within 48 hours.
