As TAVI Advances, Adjunctive Devices Multiply
As researchers work to more fully understand the risks and durability of transcatheter aortic heart valve implantation (TAVI) procedures, device innovators are already attempting to engineer solutions to some of the more obvious areas of unmet need.

Studies suggest transcatheter aortic valve replacement is associated with a higher stroke risk than standard surgical valve replacement, presumably due to embolic debris released during the TAVR procedure. To address this concern, several companies are developing TAVR-specific embolic protection devices, and their success may prove to be a key driver of future growth in this $1+ billion market.
Although Edwards is the pioneer and market leader in TAVR, there is no shortage of competitors – in both the aortic and mitral valve segments – developing next-generation devices who would be happy with a fraction of this potential multibillion-dollar opportunity.
The prospective medical device tax, the continuing decline of venture investing, pricing challenges, austerity measures in Europe, and other headwinds continued to push against the medtech industry in 2012. But emerging clinical and geographic markets, along with an active M&A market, are providing the industry with some momentum going into 2013.
