Impella®-Supported PCI in High-Risk Patients With Complex Coronary Artery Disease and Reduced Left Ventricular Function (NCT04763200)

Check every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).

1. Age ≥18 years and ≤90 years
2. Clinical presentation and baseline left ventricular function are as follows: Either 2A or 2B must be present A. Subject has CCS or NSTEMI with an LVEF ≤40% NOTE: The LVEF must be quantitatively measured as ≤40% by echo within 30 days assuming no change in clinical condition. If multiple echos have been performed within 30-days, the most recent test must be used to qualify the patient. NOTE: Subject qualifies if the quantitative site read LVEF is ≤30%; if the quantitative site read is \>30% - ≤40% the Echo Core Lab must confirm the LVEF is ≤40% before subject enrollment (Core Lab will provide \<48-hour turnaround). Similarly, if the site read is qualitative only (i.e., only provides broad ranges without detailed LVEF quantification), the Echo Core Lab must confirm the LVEF is ≤40% before subject enrollment. OR B. Subject has STEMI ≥24 hours and \<30 days after symptom onset with an LVEF ≤30% NOTE: In patients qualifying with recent STEMI, the LVEF must be demonstrated to be ≤30% by quantitative echocardiography after the primary PCI procedure (if performed) and within 72-hours prior to the planned randomization. If primary PCI was not performed, the qualifying echocardiogram will be the one taken during the index hospitalization closest to the index procedure. If the site read is qualitative only (i.e., only provides broad ranges without detailed LVEF quantification), the Echo Core Lab must confirm the LVEF is ≤30% before subject enrollment.
3. Local heart team (interventional cardiologist and cardiac surgeon) has determined that PCI is indicated and is the most appropriate management for the patient
4. Complex PCI will be performed: Either 4A or 4B must be met A. One of the following must be present: i. Triple vessel disease is present (visually-assessed angiographic DS ≥80% \[or ≥40% if non-invasive evidence of ischemia on a localizing stress test or invasive evidence of ischemia (FFR ≤0.80 or iFR ≤0.89)\] is present in all 3 epicardial coronary artery distributions in a main vessel or branch with visually-assessed reference vessel diameter ≥2.5 mm) with PCI planned in ≥2 of these vessels in the proximal or mid LAD, proximal or mid-LCX or proximal, mid- or distal RCA \[i.e., not a branch vessel\]) OR ii. Left main distal bifurcation or trifurcation disease (visually-assessed DS ≥50% \[or DS ≥30% if non-invasive evidence of ischemia in both the anterior and posterolateral distributions or left main IVUS MLA ≤6.0 mm2 or FFR ≤0.80 or iFR ≤0.89\] is present) with planned intervention of the left main plus at least 2 branch vessels (i.e., the ostial LAD, ostial LCX or ostial ramus) OR iii. Left main equivalent disease with both ostial LAD and ostial LCX having visually-assessed angiographic DS ≥80% \[or ≥40% if non-invasive evidence of ischemia on a localizing stress test or invasive evidence of ischemia (FFR ≤0.80 or iFR ≤0.89\] and requiring intervention in both branches OR iv. Intervention of the last remaining vessel (native coronary artery or bypass graft) OR B. Multivessel disease is present (visually-assessed angiographic DS ≥80% \[or ≥40% if non-invasive or invasive evidence of ischemia is present\] in ≥2 of the 3 epicardial coronary artery distributions in a main vessel or branch with visually-assessed reference vessel diameter ≥2.5 mm) and PCI is planned of at least 2 separate complex lesions in main vessels or branch vessels each having one or more of the following characteristics: i. Long lesion (≥28 mm visually assessed) requiring ≥30 mm stent length (single or multiple) ii. Severe angiographic calcification (see Protocol definition) or requiring atheroablation iii. Any left main morphology not in Criterion A requiring intervention (e.g., isolated ostial or mid-shaft left main lesion or distal left main bifurcation lesion with a planned single provisional stent technique) iv. Non-left main bifurcation lesion requiring intervention in both the main branch and side branch v. CTO (TIMI 0 Flow) vi. Giant thrombus (length ≥3x vessel diameter) vii. SVG (other than focal (\<5 mm) disease of the proximal or distal anastomosis or in-stent restenosis) NOTES:
5. The multiple lesions can be in the same vessel if separated by ≥10 mm - however, each separate lesion has to have one or more of the above characteristics
6. PCI may be performed on additional non-qualifying lesions (i.e., without 1 or more of the above high-risk characteristics) as long as there are at least two lesions also undergoing PCI with each having 1 or more of the above characteristics)
7. There are 2 exceptions to the rule that each separate lesion must have one or more of the above characteristics (as in Inclusion Criterion 4B above): The subject may qualify if undergoing complex PCI of a single lesion that has 2 or more of the above complex characteristics (as in Inclusion Criterion 4B above) if also: i. There is a CTO of a proximal or mid-LAD, proximal or mid-LCX or proximal, mid- or distal RCA (i.e., not a branch vessel) that will not be treated OR ii. The subject qualifies with recent STEMI with an LVEF ≤30% and the complex PCI is planned in a non-infarct vessel (i.e., a complex PCI in the infarct vessel does not qualify)
8. Subject or legal guardian (permitted at US sites only) agrees to randomization and to follow all study procedures and provides informed, written consent
