What was done
This narrative review synthesized the relationship between regular physical activity and thoracic aortic dilation. The authors evaluated physiological aortic root enlargement seen in athletes versus pathological dilation in individuals with inherited aortopathies (such as Marfan syndrome and bicuspid aortic valve) and discussed implications for sports eligibility.
What was found
The abstract reports no numerical data. Qualitatively, it reports that mild aortic root enlargement can occur as a normal adaptation to regular exercise training in athletes. In contrast, high-intensity physical activity in individuals with genetic aortopathies can promote excessive enlargement and trigger acute aortic dissection. Tailored decisions are advised based on aortic valve and root dimensions and genetic testing, though individual risk remains difficult to stratify.
Why it matters
It emphasizes the clinical need to differentiate benign exercise-induced aortic remodeling from dangerous inherited aortopathies to prevent exercise-triggered aortic dissection.
Limits
The abstract contains no quantitative metrics, sample size, or systematic methodology. It highlights that the risk of aortic complications during sports in patients with genetic aortic disease remains poorly characterized.
