title: An unusual case of aortic dissection in Turner's syndrome.
abstract: Cardiovascular malformations are common in patients with Turner's syndrome. Aortic coarctation and bicuspid aortic valve are the most frequently occurring abnormalities, and are associated with cystic medial necrosis of the aortic wall. Aortic dissection is an uncommon but catastrophic complication of the 'aortopathy' of Turner's syndrome. We report the unusual case of a Turner's syndrome patient (with a bicuspid aortic valve and previous coarctation repair) who died following an intramural haemorrhage of the aortic root that was complicated by dissection and rupture, with no evidence of aortic intimal tear. The role of intramural haemorrhage in the pathogenesis of acute aortic syndromes in Turner's syndrome patients is unclear. The condition may be associated with atypical clinical presentations, it can be difficult to confirm with imaging techniques, and it carries a high risk of progression to classical aortic dissection and death. This case therefore highlights the need for a high index of suspicion when assessing Turner's syndrome patients presenting with chest pain syndromes. Furthermore, the effective management of Turner's syndrome patients with cardiovascular abnormalities requires the development of evidence-based preventive (such as echocardiographic surveillance of aortic dilatation) and interventional strategies.
