This is the most common cardiac congenital anomaly affecting 0.5 to 2% of the population The general rule. BVA may be associated with structural damage to the ascending aorta, which exposes BVA patients to a risk of developing ascending aortic aneurysm and acute aortic accidents. Recent data from the literature have revealed that the natural history of BVA is marked by a possible development towards significant valvulopathy and \u002F or an ascending aortic aneurysm often requiring surgical treatment. However, the natural history of bicuspid disease remains poorly understood and the prognostic factors for progression to severe valvulopathy and \u002F or aneurysmal dilatation of the ascending aorta remain to be determined.",[51],"Aortic Valve, Bicuspid","2026-06-12",{"date":54,"type":55},"2026-06-15","ACTUAL",{"date":57,"type":55},"2010-09-16",{"date":59,"type":47},"2035-04",{"name":5,"class":6},1]
