Primary Outcome Measures:
  • Reduction in the incidence of CIN in subjects. [ Time Frame: Through 72 hours post-procedure ] [ Designated as safety issue: No ]
    CIN is defined as a post-procedure relative serum creatinine increase ≥ 25% or an absolute serum creatinine increase of ≥ 0.5 mg/dL).

  • Evaluating bleeding/transfusion events. [ Time Frame: Through 30 days post-procedure ] [ Designated as safety issue: Yes ]

    Bleeding/transfusion events evaluated:

    • Blood loss requiring transfusion of ≥ 2 units
    • Thrombolysis in Myocardial Infarction (TIMI) Major Bleeding
    • TIMI Minor Bleeding

  • Evaluating local events. [ Time Frame: Through 30 days post-procedure. ] [ Designated as safety issue: Yes ]

    Events evaluated include:

    • Coronary sinus perforation, dissection, or occlusion that requires treatment or results in MI or death
    • Pericardial effusions (including pericardial tamponade) requiring treatment


Secondary Outcome Measures:
  • Change in kidney function between the randomized groups. [ Time Frame: Up to 96 hours post-procedure ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: CINCOR™ System Treatment
Use of the CINCOR™ System during the PCI procedure plus Standard of Care peri-procedural hydration for the prevention of CIN.
Device: CINCOR™ System
Catheter based system to reduce and remove contrast media.
Active Comparator: Standard of Care
Peri-procedural hydration with isotonic saline or sodium bicarbonate for at least 2 hours prior to the procedure and 6-12 hours post-procedure.
Drug: Peri-procedural hydration
Parenteral administration of fluids (saline or bicarbonate solutions) prior to and after a PCI procedure. This is considered to be minimum standard of care for CIN prevention.

Detailed Description:

The CINCOR™ Catheter System to retrieve contrast media from the coronary sinus following injection during percutaneous coronary interventions.
