While transcatheter aortic valve replacement (TAVR) is a paradigm shift in how valve disease is treated, one nagging safety issue that remains is TAVR’s stroke rate, which is higher than traditional surgical valve replacements. The solution to this issue may be the use of specialized embolic protection systems, of which four companies displayed their devices on the show floor and in presentations at the 26th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium in September.
