Increased prevalence of bicuspid aortic valve in Turner syndrome links with karyotype: The crucial importance of detailed cardiovascular screening

Original language description

Background: Bicuspid aortic valve (BAV) represents one of the strongest risk factors for aortic dissection in Turner syndrome (TS). An exact relation between the occurrence of BAV and a particular karyotype has not been established yet. The aim of this study was to determine the association between karyotype and prevalence of BAV.Methods: Sixty-seven TS patients aged between 6.6 and 32.5 years underwent cardiac magnetic resonance imaging (MRI) study. They were divided into four cytogenetic subgroups -45, X karyotype (n = 27); 45, X/46, XX mosaicism (n = 17); structural abnormalities of the X chromosome (n = 10); and 45, X/structural abnormality of the X chromosome mosaicism (n = 13). Prevalence of BAV and odds ratio (OR) compared with the general population in the whole study group, and statistical comparison of prevalences of BAV among the individual subgroups were determined.Results: Prevalence of BAV in the whole study group was established as 28.4% [OR 208.3 (95% CI -103.8-418.0); p-value &lt; 0.0001]. Individuals with 45, X karyotype had the highest prevalence of BAV -40.7%, p-value &lt; 0.0001. Presence of any 45, X cell line in karyotype significantly predisposed to BAV (p-value = 0.05).Conclusions: The 45, X karyotype is associated with the highest prevalence of BAV. Also, the presence of the 45, X cell line in any mosaic karyotype increases the probability of BAV.
