1. Atherosclerosis of the ascending aorta as a risk factor for stroke after cardiac surgery : a study based on epiaortic ultrasound
Sammanfattning : Postoperative stroke is a dreaded problem in cardiac surgery and atherosclerosis of the ascending aorta (AAA) is an important risk factor. The risk from calcified AAA, the extent and the topography of the disease in the development of stroke was evaluated. LÄS MER
2. Familial thoracic aortic aneurysms and dissections : studies on genotype and phenotype
Sammanfattning : Background: Thoracic aortic aneurysms and dissections (TAAD) have a genetic component with an estimated 20-25% of the patients having a positive family history. An aneurysm often precedes a dissection. Acute aortic dissections are associated with high mortality and morbidity, even when operated on. LÄS MER
3. The bicuspid aortic valve : studies on valve morphology and pathology in relation to ascending aortic dilatation and coronary artery disease
Sammanfattning : The prevalence of bicuspid aortic valve (BAV) is 1-2% and is thereby the most common cardiac malformation. BAV is highly associated with valvular dysfunction and aortic conditions such as ascending aortic aneurysm and aortic dissection. Of BAV individuals, 25-50% will develop indications for surgical intervention. LÄS MER
4. The effect of pressure afterload due to aortic coarctation on left ventricular function in children
Sammanfattning : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. LÄS MER
5. GLP-1 secretion and signaling in patients with aneurysmal enlargement of the thoracic aorta : a potential contributor to reduced prevalence of aneurysm in diabetes
Sammanfattning : An aortic aneurysm is a localized dilation of the artery, greater than 50% of the normal size. It is the result of a weakening of the aortic wall, and untreated or unrecognized aortic aneurysms may be fatal due to massive internal bleeding, as a result of dissection or rupture of the aneurysm.
