Study note

Transcatheter aortic valve implantation

THE CONTEXT

Transcatheter aortic valve implantation (TAVI)* is an alternative to surgical aortic valve replacement, especially for aortic stenosis.

•

The native valve remains in place and is compressed by a new bioprosthetic valve implanted within it.

•

The bioprosthetic valve is mounted on a large stent-like structure and delivered through a catheter inserted in the femoral artery.

•

TAVI avoids sternotomy and is associated with a short recovery period.

•

It can be used in high-risk and otherwise inoperable patients and is better tolerated by older patients.

•

Reported complications include stroke in 2% and heart block requiring pacemaker implantation in 5%–15%.
