A newly developed endovascular procedure that is about to undergo testing
in clinical trials in the United States and Europe may offer hope for patients
too elderly or sick to be candidates for open heart surgery for aortic valve
replacement. If proven in that arena, proponents suggest, the approach also
may one day replace conventional aortic valve surgery .
The trials were proposed after a successful percutaneous transcatheter
implantation of a prosthetic valve was performed in France on a 57-year-old
man with a severely calcified aortic valve (Circulation. 2002;106:3006-3008).
