The Complicated Genetics Behind Uncomplicated Type B Aortic Dissection.

Introduction: Up to 50% of uncomplicated type B aortic dissection (unTBAD) cases progress to become complicated with a mortality rate of up to 42% within 5 years of onset. Morphological and clinical parameters have previously been defined for the decision of surgical intervention in unTBAD to improve clinical outcomes. The analysis of genetic variants in this risk stratification has demonstrated a lack of evidence to influence clinical decision-making.
