Why the study?
High mortality in untreated acute type A aortic dissection stresses the need for prompt diagnosis and immediate surgery, motivating evaluation of the frequency and clinical impact of misdiagnosis and delayed diagnosis.
Does initial misdiagnosis or delayed diagnosis impact 30-day mortality and surgical treatment rates in patients with acute type A aortic dissection?
Does initial misdiagnosis or delayed diagnosis impact 30-day mortality and surgical treatment rates in patients with acute type A aortic dissection?
Initial misdiagnosis of acute type A aortic dissection is common, particularly in women, and delayed diagnosis significantly increases 30-day mortality in patients without malperfusion due to lower rates of surgical treatment.
No takes yet. Share an insight, caveat, or question.
Delayed diagnosis was associated with higher mortality in ATAAD without malperfusion; leaves open whether faster recognition improves surgical access.
Teurneau-Hermansson et al. (2025) studied this question.
