Aortic dissection and turner’s syndrome: case report and review of the literature

Cardiovascular abnormalities are frequently encountered in patients with Turner's syndrome. These include coarctation of the aorta, aortic root dilatation, bicuspid aortic valve, atrial and ventricular septal defects. Aortic dissection is a rare but devastating complication of Turner's syndrome that usually occurs in adulthood. We report a case of Turner's syndrome with coarctation of the aorta and chronic aortic dissection, and review the relevant literature. There have been 21 prior reported cases of aortic dissection in patients with Turner's syndrome. Possible etiologic factors contributing to the occurrence of aortic dissection in this syndrome are protean. They include the presence of cystic medial necrosis, coarctation of the aorta, bicuspid aortic valve, aortic root dilatation, and hypertension, although cases of aortic dissection and Turner's syndrome have been described in patients without any risk factors. As our knowledge of the natural history of congenital heart defects and risk factors for aortic dissection in Turner's syndrome is limited, periodic cardiac evaluation of these patients may be warranted. Early recognition and treatment of this potentially lethal complication of Turner's syndrome is essential.
