REduction of Contrast Via DyeVert Used in CTO Procedures

REduction of Contrast Via DyeVert Used in CTO Procedures (REDUCe)

The is an observational, prospective study to evaluate the effect of the DyeVert System on contrast volume administration in patients undergoing clinically-indicated chronic total occlusion (CTO) percutaneous coronary intervention (PCI)

The DyeVert System is a disposable, FDA-approved device that interfaces with standard manifold systems to reduce the amount of contrast used in catheterization procedures, while maintaining fluoroscopic image opacity.

No study has assessed use of the system in CTO PCI. It would be expected that savings in CTO procedures may be less than non-CTO procedures due to catheter sizing and number of open guide injections required. Open guide injections through larger catheters do not provide for the as much resistance, therefore decreasing the need for contrast to be diverted

Inclusion Criteria:

1. Subjects undergoing CTO PCI at each of the participating centers.
2. Contrast volume recorded during CTO PCI
3. Subjects included in the "Multicenter Registry of Chronic Total Occlusion Interventions" study (Allina IRB approval # 948134-1)

Exclusion Criteria:

None
