It might be associated with other heart defects like VSD (30-60%), aortic regurgitation (20-30%), BAV (10%), and aortic stenosis (6.5%).
(5) Reports concerning unruptured, isolated ASV associated with BAV are rare.
Many theories have been postulated about the cause of aortopathy in BAV. Altered hemodynamics due to aortic stenosis and regurgitation and also defects in aortic media like elastin fragmentation, decreased fibrillin, matrix disruption, loss of smooth muscle and increase in collagen have been thought to be the cause.
Recent studies reported that adult patients with BAV have abnormal elastic properties of the ascending aorta (11-15).
We hypothesized that the diameters and elastic properties of the abdominal aorta may also be affected in patients with BAV.
The study group consisted of 35 patients with BAV and the control group consisted of 35 healthy with normal aortic valve who were matched for gender and age.
Similarly, BAVs with segment 12 belonging to cluster type III were also distributed in both Southeast and East Asia.
Banna virus (BAV) is a 12-segment, double-stranded RNA virus that is classified in the family Reoviridae and the genus Seadornavirus (1).
In the period from 1 January 2000 to 31 December 2011, 292 consecutive subjects with BAV were evaluated at the Sports Medicine and Exercise Centre of the University of Florence.
In all groups, the presence of BAV was investigated by a 2D echocardiographic exam to estimate the prevalence of the different BAV morphologies.
In this study, 20 new BAV isolates were obtained from mosquitoes collected from July through September during 2006 to 2007 at sites in Gansu Province (latitude 32[degrees]-35[degrees]N, 104[degrees]-107[degrees]E), Liaoning Province (39[degrees]-41[degrees]N, 123[degrees]-125[degrees]E), Shanxi Province (37[degrees]-38[degrees]N, 111[degrees]-113[degrees]E), and Inner Mongolia Province (41[degrees]-43[degrees]N, 121[degrees]-123[degrees]E) (Table, Figure 1).
Viruses were isolated and BAV isolates were identified using described procedures (8).
