Coronary Artery Disease Myocardial Infarction | Device: Lithotripsy | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 384 participants |
Allocation: | N/A |
Intervention Model: | Single Group Assignment |
Intervention Model Description: | The Coronary IVL System is a proprietary balloon catheter system designed to enhance stent outcomes by enabling delivery of the calcium disrupting capability of lithotripsy prior to balloon dilatation at low pressures. The Coronary IVL System consists of an IVL Balloon Catheter with two integrated pairs of lithotripsy emitters, a Lithotripsy Generator, and Connector Cable. |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |

Experimental: Coronary Lithotripsy System
All subjects will receive lithotripsy treatment from the Shockwave Medical Coronary IVL System
|
Device: Lithotripsy
Deliver Lithotripsy to the target vessel prior to placing a coronary stent. |
- No. of participants with treatment and device related adverse events. Adverse Events must meet definition of (MACE) Major Adverse Cardiac Events [ Time Frame: within 30 days of index procedure ]
Definition of MACE:
- Cardiac death; or
- Myocardial Infarction (MI) defined as CK-MB level > 3 times the upper limit of lab normal (ULN) value with or without new pathologic Q wave at discharge (periprocedural MI) and using the Fourth Universal Definition of Myocardial Infarction beyond discharge (spontaneous MI); or
- Target Vessel Revascularization (TVR) defined as revascularization at the target vessel (inclusive of the target lesion) after the completion of the index procedure
- No. of participants that had a successful index procedure and without in-hospital MACE [ Time Frame: at the end of the procedure ]Successful procedure is defined as delivering lithotripsy to the target vessel and placing a coronary stent with residual stenosis of less than 50% (Core lab assessed) and without in-hospital MACE. MACE definition is defined in outcome 1

Inclusion Criteria:
- Subject is ≥18 years of age

- For patients with unstable ischemic heart disease, biomarkers (troponin or CK-MB) must be less than or equal to the upper limit of lab normal within 12 hours prior to the procedure (note: if both labs are drawn, both must be normal).
-
For patients with stable ischemic heart disease, biomarkers may be drawn prior to the procedure or at the time of the procedure from the side port of the sheath.
- If drawn prior to the procedure, biomarkers (troponin or CK-MB) must be less than or equal to the upper limit of lab normal within 12 hours of the procedure (note: if both labs are drawn, both must be normal).
- If biomarkers are drawn at the time of the procedure from the side port of the sheath prior to any intervention, biomarker results do not need to be analyzed prior to enrollment (note: CK-MB is required if drawn from the sheath).
- Left ventricular ejection fraction >25% within 6 months (note: in the case of multiple assessments of LVEF, the measurement closest to enrollment will be used for this criteria; may be assessed at time of index procedure)
- Subject or legally authorized representative, signs a written Informed Consent form to participate in the study, prior to any study-mandated procedures
-
Lesions in non-target vessels requiring PCI may be treated either:
- >30 days prior to the study procedure if the procedure was unsuccessful or complicated; or
- >24 hours prior to the study procedure if the procedure was successful and uncomplicated (defined as a final lesion angiographic diameter stenosis <30% and TIMI 3 flow (visually assessed) for all non-target lesions and vessels without perforation, cardiac arrest or need for defibrillation or cardioversion or hypotension/heart failure requiring mechanical or intravenous hemodynamic support or intubation, and with no post-procedure biomarker elevation >normal; or
- >30 days after the study procedure
Angiographic Inclusion Criteria
- The target lesion must be a de novo coronary lesion that has not been previously treated with any interventional procedure
-

- Stenosis of ≥70% and <100% or
- Stenosis ≥50% and <70% (visually assessed) with evidence of ischemia via positive stress test, or fractional flow reserve value ≤0.80, or iFR <0.90 or IVUS or OCT minimum lumen area ≤4.0 mm²
- The target vessel reference diameter must be ≥2.5 mm and ≤4.0 mm
- The lesion length must not exceed 40 mm
- The target vessel must have TIMI flow 3 at baseline (visually assessed; may be assessed after pre- dilatation)
- Evidence of calcification at the lesion site by, a) angiography, with fluoroscopic radio-opacities noted without cardiac motion prior to contrast injection involving both sides of the arterial wall in at least one location and total length of calcium of at least 15 mm and extending partially into the target lesion, OR by b) IVUS or OCT, with presence of ≥270 degrees of calcium on at least 1 cross section
