Efficacy and Safety of Routine Postdilation in Balloon-Expandable Transcatheter Aortic Valve Implantation Platform: The DUOTAP Randomized Clinical Trial.
JAMA cardiology·November 3, 2026·PMID 42976368
Why it mattersAsymmetric valve expansion after TAVI is linked to prosthetic dysfunction and mortality, yet postdilation has lacked randomized evidence. This trial provides high-level data that routine postdilation optimizes valve geometry and hemodynamics without added procedural risk, informing procedural strategy for suitable patients.
