Turner syndrome (TS) is a rare chromosomal disease with increased cardiovascular morbidity and mortality. The aim of this study was to investigate the influence of physical activity and diet quality on cardiovascular morbidity in German TS women. An anonymous online questionnaire was established. The questionnaire was based on the 2020 WHO recommendations on physical activity and sedentary behaviour and included the 14-Item Mediterranean Diet Assessment Tool. In addition, TS patients were asked about existing cardiovascular conditions. In total, 83 TS women were included in the final analysis. The achievement of <600 Metabolic Equivalent-minutes per week for recreational activities was significantly associated with the presence of arterial hypertension (p = 0.006). High adherence to the Mediterranean diet was achieved by only 20.5% of TS subjects and tended to be inversely associated with the presence of lipid metabolism disorders (p = 0.063). Only 37.3% of TS participants received nutritional counselling. Given the increased cardiovascular risk, specific counselling for lifestyle optimisation may play an important role in the management of TS. Further studies are required to evaluate the effects of regular aerobic physical training and different nutritional programs on cardiovascular morbidity in TS.

Turner syndrome (TS) is a rare disorder affecting 25-50 in 100000 female newborns. Bicuspid aortic valve (BAV) is assumed to be the most common congenital heart defect (CHD) in TS. In literature, reported BAV prevalence in TS ranges between 14% and 34%. The specific BAV prevalence in TS is still unknown. The aim of this study was to give a more precise estimation of BAV prevalence in TS by conducting a meta-analysis of TS-studies, which detected BAV by either cardiac magnetic resonance imaging (MRI) or cardiac computed tomography (CT). We searched PubMed, Cochrane Library, and Web of Science databases to collect observational studies including the prevalence of BAV identified by cardiac MRI or cardiac CT in TS patients up to June 4th, 2021. After screening for inclusion, data extraction, and quality assessment by two independent reviewers, the meta-analysis was performed with R 4.1.1 software. Results are shown as proportion and weighted mean difference with 95% confidence intervals (95% CI). In total, 11 studies involving 1177 patients were included. Pooled data showed that the prevalence of BAV in TS patients was 23.7% (95% CI: 21.3% to 26.1%). No high heterogeneity was found between the included studies. The current meta-analysis reveals that BAV can be detected in 23.7% of TS patients receiving cardiac MRI or cardiac CT. Therefore, BAV can be considered as the most common CHD in TS. Compared to TTE, cardiac MRI and cardiac CT might represent superior imaging modalities in BAV assessment of adult TS patients.

Background: This study aimed to investigate whether the cardiovascular care of Turner Syndrome (TS) women in Germany is in accordance with the latest clinical practice guidelines established by the 2016 Cincinnati international TS meeting. Methods: An anonymous online questionnaire was created to ask TS subjects about existing cardiovascular conditions and cardiovascular care received. Depending on cardiovascular morbidity and type of medical care received, the fulfillment of the latest clinical practice guidelines for the care of TS women was assessed. Results: 120 TS patients were included in this study. The mean age of TS subjects was 36.79 years. Only 80% of subjects received annual blood pressure measurements within the TS cohort, and only 60% received cardiac imaging according to international clinical practice guidelines. More than 55% of TS women did not feel well informed about TS-specific cardiovascular risk factors by their treating physician. Conclusions: A potential lack of cardiovascular care might be present in TS women in Germany as the results of this online patient survey suggest. The cardiovascular care of TS patients, particularly cardiac imaging and patient education, needs to receive more attention.
