Ascending Aneurysms in Bicuspid Aortic Valve
The bicuspid aortic valve (BAV), the most common congenital cardiac malformation, is associated with ascending thoracic aneurysms and appears to reflect a common developmental defect. (Hahn et al., 1992; Roberts, 1970) The average time of patients with BAV undergoing surgery (of the aortic valve and/or because of complications associated with it) is a decade earlier than patients with a normall...
متن کاملMetallothionein link to bicuspid aortic valve-associated ascending aortic dilatation.
Bicuspid aortic valve (BAV) is the most common congenital heart defect, occurring in 1% to 2% of the general population.1 Given the high incidence of sequelae, including aortic valve calcification and dysfunction, congenital aortic malformations, and aortic dilatation and dissection, it may account for considerable morbidity and mortality compared with other congenital cardiac abnormalities. Th...
متن کاملAscending aortic aneurysm and aortic valve dysfunction in bicuspid aortic valve disease.
BACKGROUND The relationship of aortic valve dysfunction and ascending aortic aneurysm is unclear in adults with bicuspid aortic valve disease. METHODS We retrospectively studied 134 consecutive out-patients (98 men, 36 women aged 43 ± 18 years) with bicuspid aortic valve disease. To investigate the relationship of ascending aortic aneurysm and aortic valve dysfunction we exclusively considere...
متن کاملValve mediated hemodynamics and their association with distal ascending aortic diameter in bicuspid aortic valve subjects.
PURPOSE Valve mediated hemodynamics have been postulated to contribute to pathology of the ascending aorta (AAo). The objective of this study is to assess the association of aortic valve morphology and hemodynamics with downstream AAo size in subjects with bicuspid aortic valve (BAV) disease. MATERIALS AND METHODS Four-dimensional flow MRI at 1.5 or 3 Tesla was used to evaluate the hemodynami...
متن کاملPredictors of ascending aortic dilatation with bicuspid aortic valve: a wide spectrum of disease expression.
OBJECTIVE This study aimed to describe the features and identify the predictors of ascending aorta dilatation in patients with congenital bicuspid aortic valve (BAV). METHODS In 280 adult patients with isolated BAV undergoing echocardiography, multivariate logistic regression models, including clinical and echocardiographic variables, were developed to predict dilatation (aortic ratio exceedi...
