Outcome Measures
Primary Outcomes (2)
Percentage of Participants Who Experienced Freedom From MACE Within 30 Days Post-procedure
The primary safety endpoint was freedom from major adverse cardiac events (MACE) at 30 days - a composite of cardiac death, myocardial infarction (MI) and target vessel revascularization (TVR). The primary endpoints were analyzed using the Intent To Treat (ITT) population.
Within 30 days of index procedure
Percentage of Subjects With Procedural Success
The primary effectiveness endpoint was Procedural Success defined as stent delivery with a residual in-stent stenosis \<50% (core laboratory assessed) and without in-hospital MACE
12-24 hours post procedure or at discharge, whichever is earlier, but at least 6 hours post procedure
Secondary Outcomes (64)
Number of Participants With Device Crossing Success
At end of procedure, with a mean total procedure time of 62.5 minutes
Number of Participants With Angiographic Success (Residual Stenosis <50%)
At end of procedure, with a mean total procedure time of 62.5 minutes
Number of Participants With Procedural Success (Residual Stenosis <=30%)
12-24 hours post procedure or at discharge, whichever is earlier, but at least 6 hours post procedure
Number of Participants With Angiographic Success (Residual Stenosis <=30%)
At end of procedure, with a mean total procedure time of 62.5 minutes
Number of Participants With Serious Angiographic Complications
At end of procedure, with a mean total procedure time of 62.5 minutes
- +59 more secondary outcomes
Study Arms (1)
Coronary Lithotripsy System
EXPERIMENTALAll subjects will receive lithotripsy treatment from the Shockwave Medical Coronary IVL System
Interventions
Deliver Lithotripsy to the target vessel prior to placing a coronary stent
Eligibility Criteria
You may qualify if:
- Subject is ≥18 years of age
- Subjects with native coronary artery disease (including stable or unstable angina and silent ischemia) suitable for PCI
- 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 prior to the index 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.
- 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
- The target lesion must be a de novo coronary lesion that has not been previously treated with any interventional procedure
- Single de novo target lesion stenosis of protected LMCA, or LAD, RCA or LCX (or of their branches) with:
- +7 more criteria
You may not qualify if:
- Any comorbidity or condition which may reduce compliance with this protocol, including follow-up visits
- Subject is a member of a vulnerable population including individuals with mental disability, persons in nursing homes, children, impoverished persons, persons in emergency situations, homeless persons, nomads, refugees, and those incapable of giving informed consent.
- Subject is participating in another research study involving an investigational agent (pharmaceutical, biologic, or medical device) that has not reached the primary endpoint
- Subject is pregnant or nursing (a negative pregnancy test is required for women of child-bearing potential within 7 days prior to enrollment)
- Unable to tolerate dual antiplatelet therapy (i.e., aspirin, and either clopidogrel, prasugrel, or ticagrelor) for at least 6 months
- Subject has an allergy to imaging contrast media which cannot be adequately pre-medicated
- Subject experienced an acute MI (STEMI or non-STEMI) within 30 days prior to index procedure, defined as a clinical syndrome consistent with an acute coronary syndrome with troponin or CK- MB greater than 1 times the local laboratory's upper limit of normal
- New York Heart Association (NYHA) class III or IV heart failure
- Renal failure with serum creatinine \>2.5 mg/dL, or chronic dialysis
- History of a stroke or transient ischemic attack (TIA) within 6 months, or any prior intracranial hemorrhage or permanent neurologic deficit
- Active peptic ulcer or upper gastrointestinal (GI) b≥leeding within 6 months
- Untreated pre-procedural hemoglobin \<10 g/dL or intention to refuse blood transfusions if one should become necessary
- Coagulopathy, including but not limited to platelet count \<100,000 or International Normalized ratio (INR) \>1.7 (INR is only required in subjects who have taken warfarin within 2 weeks of enrollment)
- Subject has a hypercoagulable disorder such as polycythemia vera, platelet count \>750,000 or other disorders
- Uncontrolled diabetes defined as a HbA1c ≥10%
- +19 more criteria
