If successful, the valve would be major advancement in treating aortic stenosis, which is diagnosed in about 100,000 people annually in the United States.

A normal aortic valve is made up of three sections, called leaflets. But sometimes people are born with a valve that has only two leaflets, known as a bicuspid aortic valve.

The size of the valve opening is critical to its function. Size is measured with an echogram (an ultrasound imaging the heart). The normal aortic valve opening is about 3.0 to 4.0 square cm in adults.

NEW ORLEANS — Transcatheter aortic valve replacement in failing transcatheter valves may not be feasible in approximately 20% of patients, and the feasibility appears to depend on aortic root ...

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body. In severe cases, it can lead to heart failure.

Bicuspid anatomy results in earlier valve degeneration, and the mean age of these patients requiring SAVR is roughly 5 years younger than those with tricuspid aortic valves. In the absence of ...

Transcatheter aortic valve implantation (TAVI) is an emerging treatment modality for aortic stenosis that has been shown to be noninferior to conventional aortic valve replacement (AVR) in ...
