Study Design

Observational model cohort
Time perspective prospective
Arm
Presence of readily apparent radiopacities within the vascular wall at the site of the stenosis, or Presence of ≤180° of calcium at one (1) cross section.
Presence of radiopacities only during the cardiac cycle before contrast injection with calcium extended partially into the target lesion, or Presence of 181° to 269° of calcium at one (1) cross section.
Presence of radiopacities noted without cardiac motion prior to contrast injection involving both sides of the arterial wall in at least one location, total length of calcium (including segmented) must be at least 15mm and extend partially into the target lesion, or Presence of ≥270° of calcium at one (1) cross section.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: 1. Subjects must be at least 18 years of age. 2. Subjects must be scheduled for percutaneous coronary revascularization involving stent deployment in de novo coronary lesions. Percutaneous coronary revascularization is defined as treatment with commercially available devices that may include but not limited to balloon angioplasty, cutting balloon, rotablation, etc. followed by the stent placement. 3. Subjects CK-MB must be less than or equal to the upper limit of lab normal value within eight (8) hours prior to procedure. If CK-MB results are not yet available prior to initiating procedure, subjects Troponin I or Troponin T must be less than or equal to the upper limit of lab normal value within eight (8) hours prior to the procedure. 4. The target lesion must be a de novo coronary lesion that has not been previously treated with any interventional procedure. 5. The target vessel must be a native coronary artery with: 1. A stenosis ≥ 70% and < 100%, or 2. A stenosis ≥ 50% < 70% with evidence of clinical ischemia 6. The target vessel reference diameter must be ≥ 2.5mm and ≤ 4.0 mm. 7. The lesion length must not exceed 40 mm. 8. The target vessel must have a Thrombolysis In Myocardial Infarction (TIMI) flow three (3) at baseline. Exclusion Criteria: 1. Inability to understand the study or a history of non-compliance with medical advice. 2. Unwilling or unable to sign the MACE clinical study ICF. 3. History of any cognitive or mental health status that would interfere with study participation. 4. Currently enrolled in any other pre-approval investigational study. This does not apply to long-term post-market studies unless these studies might clinically interfere with the current study endpoints (e.g., limit use of study-required medication, etc.). 5. Female subjects who are pregnant or planning to become pregnant within the study period. 6. Known hypersensitivity or contraindication to aspirin, heparin, ticlopidine or clopidogrel without adequate alternative medications. 7. Known sensitivity to contrast media, which cannot be adequately pre-medicated. 8. Diagnosed with chronic renal failure unless under hemodialysis, or has a serum creatinine level >2.5 mg/dl. 9. History of major cardiac intervention within 30-day, not including a PCI procedure for a staging purpose. 10. Evidence of heart failure by one of the following: i. Left Ventricular Ejection Fraction (LVEF) ≤ 25% ii. New York Heart Association (NYHA) class III or IV iii. Clinical symptoms 11. History of a stroke or transient ischemic attack (TIA) within six (6) months 12. Active peptic ulcer or upper gastrointestinal (GI) bleeding within six (6) months. 13. History of bleeding diathesis or coagulopathy or intention to refuse blood transfusion if one should become necessary. 14. Concurrent medical condition with a life expectancy of < 36 months. 15. History of immune deficiency. 16. Uncontrolled insulin dependent diabetes. 17. Evidence of active infections on the day of the index procedure. 18. Subject has planned cardiovascular intervention within 60 days post index procedure. 19. Subject with angiographically confirmed evidence of more than two (2) lesions within one (1) vessel or more than one (1) vessel requiring intervention, unless the treatment is staged. See Section 10.1 for more details. 20. Target lesion is located in a native vessel distal to anastomosis with a saphenous vein graft or Left Internal Mammary Artery/ Right Internal Mammary Artery (LIMA/RIMA) bypass. 21. Target vessel has angiographically visible or suspected thrombus. 22. Target vessel appears to be/is excessively tortuous at baseline. 23. Target lesion is an ostial location (within 5mm of ostium) or an unprotected left main lesion. 24. Target lesion is a bifurcation (side branch ≥ 1.5mm). 25. Treatment of the target lesion with the CSI coronary Diamondback Orbital Atherectomy System (OAS).

Additional Information

Official title Multi-center Prospective Study to Evaluate Outcomes of the Moderate to Severely Calcified Coronary Lesions (MACE)
Principal investigator Samin K Sharma, MD
Description This prospective, non-randomized, multi-center study includes subjects who meet all of the inclusion and none of the exclusion criteria and sign the ICF. This study may treat up to approximately 500 subjects at up to 50 active sites in the U.S. Subjects will be followed up to three (3) years. Subjects will be stratified into one (1) of three (3) arms based on the degree of calcification in the coronary lesion as defined by this protocol. An interim analysis of standard of care treatment used will be performed after an arm has 40 subjects whom have completed the discharge visit. The duration of the study is expected to be approximately four (4) years.
