ACURATE neo2 Under-Expansion | JACC Deep Dive
Update: 2025-07-21
Description
JACC's July 29 issue explores why the ACURATE neo2 valve failed in its IDE trial, with a post-hoc analysis pointing to under-expansion in heavily calcified anatomies as a potential culprit. Though the valve is off the market, the findings raise critical questions about procedural success, device design, and future innovation in TAVR. Listen to our Deep Dive narrated by JACC Editor-in-Chief Harlan M. Krumholz, MD, SM, FACC, as he goes into the science behind the peer review.
