Aortic & peripheral vascular diseaseCohort study

Prevalence and predictors of extra-aortic aneurysms in Marfan syndrome

HeartPublished

  • multicentre retrospective cohort study
  • three tertiary centres
  • systematic chart and imaging adjudication

Authors' conclusion

Extra-aortic vascular involvement is common in Marfan syndrome and closely linked to advanced aortic pathology. These findings support risk-stratified vascular imaging beyond the thoracic aorta in higher-risk patients.
