  "abstract": "Thoracic aortic dissection is often approached as an acute and localised event, and pathological examination has traditionally focused on the dissected segment. In daily practice, however, most clinicians recognise that the dissection itself is rarely the starting point of disease. Structural abnormalities of the aortic wall are frequently present long before rupture occurs and may extend well beyond the site of failure.At the same time, the diagnostic landscape of thoracic aortic disease is changing rapidly. Advances in genetic and molecular techniques have increased the detection of potentially disease-causing variants, but their clinical interpretation remains challenging. In this setting, histopathological examination of the aortic wall provides essential phenotypic context and continues to play a key role in recognising and interpreting genetic disease. The value of pathology, however, depends strongly on the representativeness of the sampled tissue.In this Brief Communication, we discuss why routine reliance on dissected aortic tissue may be insufficient to characterise the underlying disease process. We argue for a more deliberate approach to tissue selection, with attention to macroscopically intact aortic segments, and highlight the importance of standardised reporting and appropriate biobanking infrastructure. Despite ongoing advances in genomic medicine, careful pathological examination of the aorta remains a cornerstone in understanding thoracic aortopathy.",
