Background
Turner’s syndrome (TS) is the most common genetic abnormality affecting females and is characterised by complete or partial absence of the X chromosome. Mortality is predominantly related to cardiovascular disease (1). Risk of life-threatening aortic dissection is 40 per 100,000 (2). Indexed aorta size (ASI) to body surface area (BSA) >20mm/m² is considered abnormal. An ASI of ≥25mm/m² is associated with increased risk of aortic dissection (3). Despite this there is a paucity of data in the literature regarding TS cardiovascular disease and providing evidence-based care can be challenging.
Purpose
Define cardiovascular disease, with focus upon aortopathy in our TS Cardiovascular Clinic (TCC).
Methods
Single centre retrospective medical record analysis of 248 women with TS (2021-2024)
Results
Patient baseline characteristics; mean age 37 years (range 18-75yrs), height 150cm (132-169cm), weight 62kg (37-130kg), BSA 1.55m² (1.19-2.17m²). 65 patients (29%) had bicuspid aortic valve (BAV), 19 (8%) and 5 (3%) had repaired and un-repaired aortic coarctation (CoA) respectively. 30 (13%) had other congenital heart disease, with most common was partial anomalous pulmonary venous connection (12 patients: 5%).
22/248 patients had previous aortic root surgery; 20 elective (mean ASI 29mm/m², range 26-33mm/m², mean age at time of surgery 42 years); 2 presented with aortic dissection (ASI 21mm/m²; pregnant, BAV & 24mm/m²; tri-leaflet aortic valve, TAV).
Data was available for 221 unoperated patients (figure 1). The site of maximal dimension was observed at the sinus of Valsalva in 70% compared to 30% at the ascending aorta.
130 patients (59%) had maximal ASI of 25mm/m². 4 patients (2%) had an absolute maximal dimension of 40mm with ASI of 23mm/m² for all four. 9/11 patients with dimension ≥25mm/m² or 40mm had a body mass index (BMI) >25kg/m². Review of medical history for patients at and above threshold for risk of aortic dissection revealed referral to or previous discussion in an Aortic multi-disciplinary meeting (MDT) with a plan for ongoing surveillance.
57 patients (35%) with TAV had significant aortopathy (mean age 46years, range 19-75years) compared with 33 (51%) with BAV (mean age 39yrs, range 22-72 years) (figure 2). Review of patients >55years of age demonstrated a very similar burden of aortopathy i |
