Abnormal flow patterns in the aortas of those with bicuspid aortic valves (BAVs) are increasingly recognized as important in the pathogenesis of aortic dilatation but pulmonary flow patterns in bicuspid pulmonary valves have not been studied. Bicuspid pulmonary valve disease is rare and a small numbers of case reports describe concomitant pulmonary artery dilation similar to the dilation of the...

We appreciate the interest of Dr Heidrich and his colleagues in our recent report. We agree overall with their comments, and we think that, until large retrospective or perspective studies clarify this issue, bicuspid aortic valve as opposed to tricuspid aortic valve should be a relative contraindication to percutaneous device closure of atrial septal defects because of the high risk of aortic ...

OBJECTIVE To assess the pattern and progression of aortic valve dysfunction by serial Doppler echocardiographic examinations in ambulatory adult patients with congenital bicuspid aortic valve. DESIGN AND SETTING Retrospective analysis of patients referred for Doppler echocardiography over a four year period. SUBJECTS Fifty one adult patients with echocardiographic diagnosis of congenital bi...

OBJECTIVE To evaluate the dimensions of the aortic root in a selected population of young males with isolated normally functioning bicuspid aortic valve. DESIGN AND SETTING Echocardiographic and Doppler evaluation of conscripts with bicuspid aortic valve at the time of military pre-enrolment screening in two military hospitals. SUBJECTS AND METHODS 66 consecutive young men with a normally f...

BACKGROUND Congenital aortic valve fusion is associated with aortic dilation, aneurysm, and rupture in girls and women with Turner syndrome. Our objective was to characterize aortic valve structure in subjects with Turner syndrome and to determine the prevalence of aortic dilation and valve dysfunction associated with different types of aortic valves. METHODS AND RESULTS The aortic valve and ...

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...

The anatomy of the proximal left coronary artery in 33 adult patients with bicuspid aortic valves was compared with that in 33 adult patients with aortic valve disease of other aetiologies and with that in 50 adult control patients with no valve or congenital heart disease. Patients with bicuspid aortic valves had a higher incidence of immediate bifurcation of the left main coronary artery, of ...

Calcific aortic valve disease represents the predominant pathology of tricuspid (trileaflet) and bicuspid aortic valves in developed countries (Ladich et al., 2011). Accounting for approxi‐ mately half of anatomically isolated aortic stenosis and 25 percent of patients with aortic regurgitation (Roberts, 1970), calcific bicuspid aortic valves requiring surgical intervention present at least two...

Bicuspid aortic valve (BAV) is a common congenital cardiac malformation affecting 1-2% of people. BAV results from fusion of two adjacent aortic valve cusps, and is associated with dilatation of the aorta, known as bicuspid valve associated aortopathy. Bicuspid valve aortopathy is progressive and associated with catastrophic clinical events, such as aortic dissection and rupture. Therefore, fre...

Background The morphology of the aortic valve is of increasing importance in the evaluation of patients with calcific aortic stenosis (AS). The finding of a bicuspid valve can influence the suitability for transcutaneous aortic valve implantation, the attention paid to the proximal aorta, and consideration of family screening. More recent work has also suggested that the type of bicuspid valve ...
