Brief summary
The FORWARD CAD IDE Study is a Prospective, Multicenter, Single-Arm, Investigational Device Exemption (IDE) Study conducted to assess the safety and effectiveness of the Shockwave Intravascular Lithotripsy (IVL) System with the Javelin Coronary IVL Catheter for the treatment of calcified, stenotic de novo coronary artery lesions prior to stenting.
Detailed description
The Shockwave Javelin Coronary IVL Catheter was developed to address the current challenges clinicians face when treating tight, difficult to cross, calcified coronary lesions and was designed as a rapid exchange catheter to deliver intravascular lithotripsy to those complex lesions in the coronary vasculature. The intended benefit of the Shockwave Javelin Coronary IVL Catheter is to allow the catheter to modify calcium in tight, difficult to cross lesions to increase the compliance of the vessel and allow further crossing of the device or additional treatment at the discretion of the physician. Up to 158 subjects (150 evaluable) subjects with moderate-to severely calcified, stenotic de novo coronary artery lesions presenting with stable angina or following stabilization after acute coronary syndrome (ACS) that are suitable for non-emergent percutaneous coronary intervention (PCI) will be enrolled at up to 35 sites. Once the pivotal cohort is fully enrolled (N=158), the study will continue to enroll an Extended Investigation cohort of up to 250 additional subjects.
Interventions
The Shockwave Intravascular Lithotripsy (IVL) System with the Shockwave Javelin Coronary Catheter is intended to treat calcified stenosis, including calcified stenoses that are anticipated to exhibit resistance to balloon crossing, full dilatation or subsequent uniform coronary stent expansion.

Inclusion criteria
General Inclusion Criteria: 1. Subject is ≥18 years of age 2. Subject is able and willing to comply with all assessments in the study. 3. Subjects with native coronary artery disease including stable angina or following stabilization after acute coronary syndromes (ACS) for non-emergent percutaneous coronary intervention (PCI) 4. Biomarkers (troponin) must be: 1. less than or equal to the upper limit of lab normal within 24 hours prior to the procedure or may be drawn from the side port of the sheath at the time of index if the PCI is a non-emergent procedure and has stable angina (result will not be known prior to procedure); OR 2. if above the upper limit of lab normal, biomarker result must be less than 5 times the upper limit of lab normal within 24 hours prior to the procedure and the following criteria must be met: • The procedure must not be emergent and the subject cannot have angina at rest. 5. Left ventricular ejection fraction (LVEF) \>30% within 6 months (note: in the case of an event (MI or Revascularization) the LVEF must be taken post-event and in the case of multiple assessments of LVEF, the measurement closest to enrollment will be used for this criterion; may be assessed at time of index procedure). 6. Subject, or legally authorized representative, signs a written Informed Consent form to participate in the study, prior to any study-mandated procedures. 7. Estimated life expectancy \>1 year. 8. Lesions in non-target vessels requiring PCI may be treated either: 1. \>30 days prior to the study procedure if the procedure was unsuccessful or complicated; OR 2. \>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 no evidence of elevated biomarkers post-procedure; OR 3. \>30 days after the study procedure Angiographic Inclusion Criteria 9. The target lesion must be a de novo coronary lesion that has not been previously treated successfully with any interventional procedure 10. Single de novo target lesion stenosis of protected LMCA, or LAD, RCA or LCX (or of their branches) 11. The target vessel reference diameter must be ≥2.5 mm and ≤4.0 mm 12. The target lesion must meet one of the following criteria: 1. Target lesion stenosis \>90% up to 40 mm in length and evidence of moderate or severe calcification at the lesion site. Moderate calcification defined as angiography with densities noted only during the cardiac cycle prior to contrast injection; severe calcification defined as angiography with fluoroscopic radio-opacities noted without cardiac motion prior to contrast injection involving both sides of the arterial wall; OR 2. Chronic total occlusion presenting with J-CTO score of 1 with evidence of calcification and occlusion length up to 20 mm. 13. Guidewire must be in true lumen, distal to the lesion, and not subintimal, prior to insertion of Shockwave Javelin Coronary IVL catheter (antegrade wire technique only) General
Exclusion criteria

Unable to tolerate antiplatelet/anticoagulation therapy per society guidelines 5. Subject has an allergy to imaging contrast media which cannot be adequately pre-medicated 6. Subject experienced an acute STEMI within 30 days prior to index procedure 7. New York Heart Association (NYHA) class III or IV heart failure 8. Subject has acute or chronic renal disease with eGFR \<30 ml/min/1.73m2 (using institutional formula) 9.

Subject has a hypercoagulable disorder such as polycythemia vera, platelet count \>750,000 or other disorders 14. Subject has an active systemic infection on the day of the index procedure with either fever, leukocytosis or requiring intravenous antibiotics 15. Subjects with clinical evidence of cardiogenic shock 16. Uncontrolled severe hypertension (systolic BP \>180 mm Hg or diastolic BP \>110 mm Hg) 17. Subjects with an estimated life expectancy of less than 1 year 18.

Planned non-coronary interventional or surgical structural heart procedures (e.g., TAVR, MitraClip, LAA or PFO occlusion, etc.) within 30 days after the index procedure 20. Subject refusing or not a candidate for emergency coronary artery bypass grafting (CABG) surgery 21.

MACE (Clinical Events Committee \[CEC\] adjudicated) is defined as: * 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 |
| Primary Performance Endpoint - Technical Success | Peri-procedural | Technical Success defined as successful Shockwave Javelin Coronary IVL-enabled lesion crossing without serious angiographic complications determined by angiographic core lab |
