Aortic root echocardiograms were recorded from 89 patients whose aortic valves had also been adequately defined by selective angiography or viewed surgically or at autopsy. The eccentricity index (E.I.) of the aortic leaflets was measured at the onset of diastole and an E.I. of 1.3 or greater was taken as abnormal. Of 31 patients with isolated nonobstruced or mildly obstructed bicuspid aortic v...

Numerical Simulations of Aortic Blood Flow with a Bicuspid Aortic Valve By Ruth D. Blum One of the most common congenital heart defects is bicuspid aortic valve (BAV), occurring in about 1% to 2% of the population. In patients with BAV the aortic valve deviates from normal in that it only has two leaflets instead of three. BAV can result in altered hemodynamics and decreased performance of the ...

We describe the case of a 53-year-old man with a severely stenotic bicuspid aortic valve combined with an unruptured aneurysm of the left sinus of Valsalva and an aberrant left coronary artery. The patient was successfully treated with aortic valve replacement and closure of the aneurysm. It is well known that patients with a bicuspid aortic valve have an increased incidence of other congenital...

Athletes, firefighters and pilots are often in intense working stress. They are prone to have heart attack, especially in the condition of a bicuspid aortic valve. Aortic regurgitation and aortic wall weakness are often complicated with bicuspid aortic valve, thereby placing these professionals in a more dangerous circumstance. An appropriate screening strategy and further annual cardiovascular...

Whether the dilatation of proximal aorta in patients with bicuspid aortic valve is secondary to hemodynamic effects related to the abnormal aortic valve or a primary manifestation of the genetic disorder remains controversial. We discuss in this paper the recent data on the BAV function and transvalvular flow patterns in relation with the dilatation type of the proximal aorta. Different morphol...

the bicuspid aortic valve is known to be the most common congenital cardiac malformation, with an approximate incidence rate of 1-2% in the general population. most patients are unaware of the disease until the onset of infective endocarditis, which is a life-threatening complication that may affect a heart valve or other cardiac structures at the site of endothelial damage. a 22-year-old man p...

Background Bicuspid aortic valves (BAV) are associated with aneurysms of the ascending aorta (AAA). It is unclear whether these aneurysms are caused by tissue alterations of the aortic wall or by alterations of blood flow in the ascending aorta due to the bicuspid valve morphology. In this study we analyzed the phase contrast 4D flow characteristics in normal tricuspid aortic valves (TAV) in a ...

Background Bicuspid aortic valve (BAV) is known to be heritable and often shows a concomitant aortopathy which was thought also to be present in some family members. While one recent study reported normal ascending aortic diameters in family members of the general BAV population, little is known about aortic function in such family members. We used advanced aortic cardiovascular magnetic resona...

A 56-year-old female with congestive heart failure was transferred to our institution. Aortography demonstrated aortic valve stenosis (AS) with a congenitally bicuspid valve and dilatation of the ascending aorta. Preoperative coronary angiography showed a left single coronary artery. Replacement of the aortic valve and ascending aorta was performed. She had an uneventful postoperative course. W...
