TAVI at 10 Years: First Study to Assess TAVI Long Term Durability
Original Title: First look at long-term durability of transcatheter heart valves: Assessment of valve function up to 10 years after implantation. Presenter: Danny Dvir. Transcatheter aortic valve implantation (TAVI) is being used in increasingly younger patients at low surgical risk, which is why longer survival is expected. The durability of transcatheter aortic prostheses has…
