In the United States about 10% of aortic stenosis is caused by rheumatic disease and the remainder by calcification of a unicuspid, bicuspid, or normal trileaflet valve.

Echocardiography revealed a calcified trileaflet aortic valve with severe stenosis (transaortic mean pressure gradient, 38 mm Hg; aortic-valve area, 0.4 cm 2) and an aortic annular diameter of 19 ...

The aortic valve is normally tricuspid or trileaflet. When two of the cusps are fused together, the valve becomes functionally “bicuspid.” Most commonly, the right and left coronary cusps are ...

There is currently no way to stop calcification of the aortic valve. If all else fails, the valve must be replaced. To better ...

A trileaflet valve made from bovine pericardium is suspended between two inflatable and deflatable ring balloons allowing for device repositioning ... Transcatheter Aortic Valve Implantation: ...

Dowling said there are a number of different sizing strategies proposed for BAVs, including annulus-based sizing which is used for trileaflet aortic valves. The second approach consists of ...

Aortic stenosis is a heart valve disease that some people don't realize they have. So what is it, how is it treated?

In patients greater than age 65, more than 90% of aortic stenosis involves trileaflet valves which have developed heavy calcification. In these instances the calcium deposits are thought to alter the ...

In patients at low surgical risk who underwent transcatheter aortic valve replacement with a balloon-expandable valve, those with bicuspid aortic valves had no excess death and stroke risk ...

Our experience with the HAART 300 Aortic Annuloplasty Devices in trileaflet aortic valve repair has shown us how the devices simplify aortic valve repair and at the same time provide durable ...
