Why the study?
Is the number of identifiable entry tears associated with aortic growth in long-term acute type B aortic dissection?
Population
Patients with long-term acute type B aortic dissection (ABAD)
Design
Cohort
Key result
In medically treated acute type B aortic dissection, having a single entry tear was associated with a significantly higher median aortic growth rate (5.8 mm/year) compared to having two entry tears (0.98 mm/year, P=0.01).

Is the number of identifiable entry tears associated with aortic growth in long-term acute type B aortic dissection?
Absolute Event Rate: 5.8% vs 0.98%
p-value: p=0.01
This study aims to determine if the number of entry tears can predict long-term aortic growth in patients with type B aortic dissection.
Tolenaar et al. (2013) conducted a cohort in Acute type B aortic dissection (n=60). One entry tear vs. Two entry tears was evaluated on Aortic growth rate (mm/year) (p=0.01). In medically treated acute type B aortic dissection, having a single entry tear was associated with a significantly higher median aortic growth rate (5.8 mm/year) compared to having two entry tears (0.98 mm/year, P=0.01).
