Hotline - ACURATE neo2 under-expansion in the ACURATE IDE study: a post-hoc analysis

PCR Perspectives

Summary

Howard Herrmann and Raj Makkar discuss a sub-study of the ACURATE IDE trial, which examined valve under-expansion detected by fluoroscopy. Among 1,500 patients with aortic stenosis, 22 % of ACURATE neo2 valves showed under-expansion, often linked to heavy valve calcification.

Patients with under-expanded valves faced higher risks of death and stroke compared to those with fully expanded valves. The discussion addresses what causes this under-expansion and how to prevent it for better outcomes.
