Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Osprey Medical CINCOR System utilizes catheter system along with institutional vacuum in which contrast media (CM) injected into the left coronary arteries is retrieved from the coronary sinus (CS). The
investigational device works by retrieving contrast agent prior to reaching the systemic circulation and the kidneys thereby helping to avoid the development of contrast induced nephropathy (CIN).
The removal catheter will be in place in the coronary sinus for the duration of the PCI procedure (approximately 1 to 2 hours). Each collection episode will require that the vacuum is activated for approximately 8-12 seconds. It is anticipated that up to 12 collection episodes will occur during a PCI procedure.

Comparator / control treatment
Single arm study, no comparator. All patients will undergo standard of care treatment, peri-procedural hydration, for the prevention of CIN.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 257864 0
Retrieval of contrast agent. Success criterion for this endpoint is 40% or greater retrieval of contrast agent. This criterion will be assessed by analyzing collected blood for iodine content by inductively coupled plasma optical emission spectroscopy (ICP-OES)
Timepoint [1] 257864 0
Measured on the day of the coronary procedure.
Secondary outcome [1] 263317 0
To describe the safety of the device by summarising all system- and procedure-related adverse events and estimating the serious system- and procedure-related serious adverse event free rate. Adverse events evaluated include:

Death, Arrhythmia (including ventricular tachycardia and ventricular fibrillation), Myocardial infarction, Pericardial hemorrhage/tamponade requiring treatment, Coronary sinus perforation, dissection, or occlusion, Blood loss requiring transfusion, Other events related to partial coronary sinus occlusion and suction. These events will be evaluated using standard medical techniques including electrocardiogram (ECG), angiography, clinical laboratory tests, and patient interview.
Timepoint [1] 263317 0
Evaluated through 30 days post-procedure. This endpoint will be evaluated at all scheduled and unscheduled study visits. Scheduled post-procedure visits occur at 1, 4, and 30 days post-procedure.

Key exclusion criteria
1. The subject is currently undergoing renal dialysis.
2. The subject is in acute renal failure or has unstable renal function based on clinical findings and/or a known change in serum creatinine of greater than or equal to 0.5mg/dL or greater than or equal to 25% within 7 days prior to enrolment compared to the last serum creatinine measurement on record.
3. The subject has received contrast media within 7 days prior to the procedure day or a second imaging study of any type which will require iodinated contrast is planned within the 4 days following the protocol-defined procedure.
4. The subject has a known allergy to iodine-based contrast agents that cannot be adequately pre-medicated (patients with a history of true anaphylaxis may not be enrolled).
5. The subject has a known bleeding diathesis (e.g. thrombocytopenia [<100,000 cells/mm3], heparin-induced thrombocytopenia, haemophilia, or von Willebrand disease, any history of intracranial bleeding, or gastrointestinal bleeding gross genitourinary bleeding).
6. The subject is currently on intravenous heparin that cannot be discontinued at least 4 hours before the procedure, intravenous bivalirudin that cannot be discontinued at least 4 hours before the procedure, intravenous abciximab that cannot be discontinued at least 24 hours before the procedure, intravenous tirofiban or eptifibatide that cannot be discontinued at least 6 hours before the procedure, or has received any low molecular weight heparin within 12 hours or factor Xa antagonist (including fondaparinux) within 24 hours of the procedure.
7. The subject is hypotensive (systolic blood pressure < 90 mmHg not corrected by intravenous saline) or requiring intravenous pressors and/or intra-aortic balloon counterpulsation.
8. The subject has decompensated heart failure requiring intravenous diuretic, inotropic, vasopressor or intraaortic balloon support in the previous 7 days.
9. The subject has had recent (within last 72 hours) acute myocardial infarction as defined in the “Universal Definition of Myocardial Infarction”:
a. Detection of rise and/or fall of cardiac biomarkers (preferably troponin) with at least one value above the 99th percentile of the upper reference limit and at least one of the following
i. Symptoms of ischemia
ii. Electrocardiogram (ECG) changes indicative of new ischemia (new ST-T changes or new left bundle branch block)
iii. Development of pathological Q waves in the ECG
iv. Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality

15. The subject has a life expectancy of less than twelve (12) months.
16. The subject has a pacemaker lead, percutaneous mitral annuloplasty or other device placed within the coronary sinus that would limit the ability to successfully cannulated the coronary sinus.
