[Transcatheter aortic valve implantation]

As the French population is aging, a growing number of elderly patients with symptomatic severe aortic stenosis are going to require therapeutic management. Approximately 30 to 40 % of these patients do not undergo surgical treatment and a high proportion is considered to be at high risk for surgery. The transluminal aortic valve implantation technique has been increasingly used over the past few years, thus providing a solution to a major therapeutic issue in our industrialized countries. Thanks to major randomized studies such as the PARTNER US trial, this treatment has been approved for high-risk patients. Expertise and new devices are now opening the way to intermediate risk population.
