title: Cardiovascular disorders in Turner's syndrome and its correlation to karyotype.
abstract: Forty-nine out of 66 patients with Turner's syndrome and different karyotypes underwent full cardiological evaluations (physical examination, electrocardiography, chest X-ray and echocardiography). Congenital cardiovascular anomalies were found in 11 patients (22.4%). Among the cardiac anomalies in patients with Turner's syndrome, aortic malformations (aortic coarctation [27%], aortic stenosis [18%] and bicuspid aortic valve [18%]) were the most frequent. We observed that the most severe malformations were found in those with karyotype 45,X or 45,X/46,XX. No anomalies were detected in patients with the X isochromosome or those mosaic with the Y component.
