Disrupt CAD Pooled OCT Analysis

Outcomes, Fracture Analysis & Stent Expansion Predictors

The individual patient data pooled analysis of 4 studies (N=262) represents the largest evaluation of IVL by OCT

Consistent OCT core laboratory evaluation across all Disrupt CAD clinical programs

* Patient enrollment in OCT sub-studies was open to all sites participating in the Disrupt CAD studies that routinely perform OCT imaging.
† Includes patients from the roll-in cohort.

Conclusions from Pooled OCT Analysis

  • The present individual patient data pooled analysis of 4 studies (N=262) represents the largest evaluation of IVL by OCT
  • OCT demonstrated extensive calcium fracture after IVL treatment with excellent stent expansion of severely calcified lesions
  • Visible calcium fracture and calcium characteristics were not predictors of stent expansion following treatment with IVL
