Study Population
High thrombus burden patients presenting with acute coronary vessel occlusion who are referred for standard of care (SOC) PCI
Criteria
Inclusion Criteria:
- Patient age ≥ 18 years
- Patient presents to treating facility within 12 hours of symptom onset
- High thrombus burden at coronary angiography, defined as TIMI thrombus grade 4 or 5 by physician visual estimate after the guidewire crosses the target lesion
- Frontline treatment with the Indigo® Aspiration System using the CAT RX Aspiration Catheter, prior to standard of care PCI
- Target lesion is located in a native coronary artery
- Informed consent is obtained from either patient or legally authorized representative (LAR)
Exclusion Criteria:
- New onset of stroke symptoms and NIHSS > 2, prior to index procedure
- Treatment with fibrinolytic therapy for index coronary vessel occlusion
- Life expectancy less than 6 months due to any comorbidities
- Patient is unwilling or unable to comply with protocol follow up schedule and/or based on the Investigator's judgment the patient is not a good study candidate
- Participation in another investigational drug or device study that may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies.
- Patient is pregnant
