2009年2月17日 · Ascending aortic dilatation occurs more frequently and at a younger age in patients with bicuspid aortic valves (BAV) than it does in patients with normal trileaflet aortic valves (TAV). The clinical significance of the correlation between BAV and dilatation of the ascending aorta is based on 2 factors.

Objectives: Guidelines for surgical correction of patients with ascending thoracic aortic aneurysm (ATAA) with a bicuspid aortic valve (BAV) have oscillated over the years. In this study, we outline the natural history of the ascending aorta in patients with BAV and trileaflet aortic valve (TAV) ATAA followed over time, to ascertain if their ...

The thoracic aortic aneurysm (TAA) in BAV frequently involves the proximal aorta, including the aortic root, ascending aorta, and aortic arch, but spares the aorta distal to the aortic arch. While the ascending aortic aneurysm might be affected by both aortopathy and hemodynamics, the aortic root aneurysm is considered to be more of a ...

2019年3月11日 · Three distinct aneurysm phenotypes were identified, which correlated with patient characteristics: Root dilatation (13 percent) — Patients tended to be younger men and have more aortic insufficiency; Ascending aortic dilatation (55 percent)

We review current concepts of anatomic classification, pathophysiology, natural history, and clinical management of bicuspid aortic valve disease with associated ascending aortic aneurysms. 1. Introduction. The bicuspid aortic valve (BAV) is the most common congenital cardiac anomaly in developed nations.

Bicuspid aortic valve (BAV) is the most common congenital cardiac malformation affecting 1% to 2% of the general population. 1 In one-third of patients, BAV is associated with significant valvular disease (aortic stenosis and regurgitation), aortic root, ascending aorta, and arch complications (dilatation and/or aneurysm of the aortic root ...

2013年4月15日 · The majority of patients with bicuspid aortic valve disease exhibit ascending aortic aneurysm in conjunction with severe aortic valve dysfunction. However, in our study 6 of 134 (5%) of persons with bicuspid aortic valve disease developed ascending aortic aneurysm without aortic valve dysfunction.

2019年4月10日 · Greater aortic stiffness and pulsatile arterial load are independently associated with faster thoracic aortic aneurysm growth in patients with bicuspid aortic valves. These relevant hemodynamic markers may be useful in novel risk algorithms for thoracic aortic aneurysm risk prediction in patients with bicuspid aortic valves.

In patients with BAV disease, ascending aorta aneurysm and moderate dilatation of the root, the significat reduction of CPB and cross-clamp times, the stability of the residual root at long term and the low risk of adverse aortic events associated with SAAR compared with the Bentall procedure have l …

It can cause aortic valve disease (stenosis and/or regurgitation), infective endocarditis and thrombus formation and is associated with ascending aortic aneurysm (AA) and dissection .
