Y Long-Term Durability of Transcatheter Heart Valves Insights From Bench Testing to 25 Years

摘要

OBJECTIVES This study assessed the long-term durability of nominally deployed transcatheter heart valves (THV) to 1 billion cycles (equivalent to 25 years) and non-nominal (overexpansion, underexpansion, and elliptical) THV deployments to 200 million cycles (equivalent to 5 years) with accelerated wear testing.
