Could Sapien Valve Weather 25 Years With Little Wear? A billion beats in bench testing say yes (Dr. John Webb, SPH)

SAN FRANCISCO — Sapien 3 transcatheter aortic valves will probably last 25 years when implanted right, bench testing showed.

After 1 billion cycles of accelerated wear testing with a pulsatile flow system — simulating 25 years of wear-and-tear in the heart in just 30 months — the TAVR valve showed “excellent” durability, John Webb, MD, of St. Paul’s Hospital in Vancouver, and colleagues found.
