The Turner syndrome is a frequently occurring chromosomal syndrome. It is characterized by X monosomy, mosaicism 45X/46XX, partial deletion of X chromosome, and various rearrangements of X chromosome, leading to several clinical features and congenital anomalies: short stature, webbing of the neck (pterygium colli), nuchal cystic hygroma, hypogonadism, with absent ovarian tissue, and renal anomalies.1 Congenital heart defects occur often in the Turner syndrome1,2; there is a high prevalence of coarctation of the aorta3-5 and bicuspid aortic valve6; ventricular septal defects, atrial septal defects, and hypoplastic left heart syndrome are less frequent.7,8
Conotruncal defects have never been reported, to our knowledge, in patients with the Turner syndrome.
