WebBicuspid aortic valve (aka BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults. WebValvular Stenosis. Stenosis of atrioventricular valves (tricuspid, mitral) or outflow tract valves (pulmonic, aortic) leads to an elevated pressure gradient across the valve as blood is flowing through the valve opening.
