Patient description: A 46-year-old man presents with dizziness and frequent headaches. He has a family history of CAD, but no other cardiovascular risk factors such as smoking, high blood pressure, and diabetes mellitus and is physically active. The patient's LDL-C and HDL-C levels were 545 and 53 mg/dL, respectively. His fasting glucose and triglyceride levels (85 and 158 mg/dL, resp.) were within normal limits. The patient reported no use of lipid-lowering medications. Neck auscultation revealed a systolic murmur 3+/6+ in the neck, radiating to the skull. Ultrasonography of the carotid arteries, revealed severe stenosis in the left internal carotid artery (LICA), as well as moderate stenosis in the right internal carotid artery (RICA) estimated between 40% and 50%. For the LICA, the peak-systolic (PSV) and end-diastolic velocity (EDV) cutoff values were 208.5 cm/s and 54.5 cm/s, respectively; RICA PSV was 91.72 cm/s and RICA EDV was 37.37 cm/s. Plaque was observed in the anterior and posterior walls of the internal carotid artery and common carotid artery, which were characterized as bulky plates extending to the middle third of the internal coronary arteries (ICAs) and as predominantly echogenic and hyperechoic, with less than 50% of the area being echolucent with uneven surfaces.

Clinical trial eligibility criteria: eligible ages (years): 18.0-999.0,  Coronary Artery Disease General 1. Patient must be at least 18 years of age. 2. Patient is able to verbally confirm understanding of risks, benefits and treatment alternatives of receiving the DynamX Novolimus Eluting Coronary Stent System (CSS) and he/she provides written informed consent, as approved by the appropriate Ethics Committee of the respective clinical site, prior to any clinical study related procedure. 3. Patient must have evidence of myocardial ischemia (e.g., stable or unstable angina, silent ischemia, positive functional study or electrocardiogram (ECG) changes consistent with ischemia) 4. Patient must be an acceptable candidate for coronary artery bypass graft (CABG) surgery 5. Patient must agree to undergo all clinical study required follow-up visits, angiograms, and IVUS testing 6. Patient must agree not to participate in any other clinical study for a period of one year following the index procedure. Angiographic Target Lesion/Vessel 1. Target lesion must be located in a native coronary artery with a nominal vessel diameter of ≥ 2.5 and ≤3.5 mm assessed visually or by online QCA 2. Target lesion must measure ≤ 24 mm in length 3. Target lesion must be in a major artery or branch with a visually estimated stenosis of ≥ 50% and < 90% with a TIMI flow of ≥ 2 4. The lesion must be successfully pre-dilated (less than 35% DS) prior to enrollment Angiographic non-Target Lesion/Vessel Treatment 1. Treatment of a single, non-target lesion located in a separate major epicardial vessel (defined as LAD with septal and diagonal branches, LCX with obtuse marginal and/or ramus intermedius branches and RCA and any of its branches) attempted during the index procedure must be completed first using an approved 'olimus drug eluting stent. The segment must be located such that any injury that might occur during intervention can be clearly attributable to the treated non-target vessel. If the procedure is deemed uncomplicated and optimal, treatment of the target lesion with the DynamX stent can be considered. Optimal lesion/vessel treatment defined as < 10% but no more than 15% residual diameter stenosis by visual assessment no evidence of dissection no evidence of thrombus in the treated lesion or vessel TIMI 3 flow Stent completely covers lesion and extends to healthy vessel on both sides (healthy to healthy) General  Patient has a known diagnosis of acute myocardial infarction (AMI) within 72 hours preceding the index procedure and CK and CK-MB have not returned within normal limits at the time of procedure 2. Patient is currently experiencing clinical symptoms consistent with AMI 3. Patient requires the use of any rotablator intervention during the index procedure 4. Patient has current unstable arrhythmias 5. Patient presenting with heart failure, chronic arrhythmia, COPD or lung function impairment 6. Patient has a known left ventricular ejection fraction (LVEF) < 30% 7. Patient has received a heart transplant or any other organ transplant or is on a waiting list for any organ transplant 8. Patient is receiving or scheduled to receive chemotherapy for malignancy within 30 days prior to or after the procedure 9. Patient is receiving immunosuppression therapy and has known immunosuppressive or autoimmune disease (e.g. human immunodeficiency virus, systemic lupus erythematosus etc.) 10. Patient is receiving chronic anticoagulation therapy (e.g., heparin, coumadin) that cannot be stopped and restarted according to local hospital standard procedures. 11. Patient has a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, clopidogrel, prasugrel or ticagrelor, Novolimus, CoCr alloys, PLLA polymers or contrast sensitivity that cannot be adequately pre-medicated 12. Elective surgery is planned within the first 6 months after the procedure that will require discontinuing either aspirin or clopidogrel or other P2Y12 inhibitors. 13. Patient has a platelet count < 100,000 cells/mm3 or > 700,000 cells/mm3, a WBC of < 3,000 cells/mm3, or documented or suspected liver disease. 14. Patient has known renal insufficiency (e.g., serum creatinine level of more than 2.5 mg/dL, or patient on dialysis) 15. Patient has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions 16. Patient has had a cerebrovascular accident (CVA) or transient ischemic neurological attack (TIA) within the past six months 17. Patient has had a significant GI or urinary bleed within the past six months 18. Patient has extensive peripheral vascular disease that precludes safe 6 French sheath insertion 19. Patient has other medical illness (e.g., cancer or congestive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the clinical study plan, confound the data interpretation or is associated with a limited life expectancy (i.e., less than one year) 20. Patient is already participating in another clinical study which has not reached the primary endpoint (long-term follow-up is not an exclusion) 21. Women of childbearing potential who have not undergone surgical sterilization or are not post-menopausal (defined as amenorrheic for at least one year) as well as women who are pregnant or nursing 22. Patient is unable to give their consent, is legally incompetent, or is institutionalized by virtue of an order issued by the courts or other authority Angiographic Target lesion(s) meets any of the following 1. Aorto-ostial location 2. Left main location 3. Tapering within target segment of 0.5mm or greater 4. Located within 10 mm of the origin of the LAD or LCX 5. Located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft 6. Lesion involving a side branch >2mm in diameter or bifurcation 7. Previous placement of a stent proximal to or within 10 mm of the target lesion 8. Total or sub-total occlusion (TIMI flow ≤ 1) 9. Excessive tortuosity or angulation (≥ 45o) proximal to or within the lesion 10. The proximal target vessel or target lesion is moderately or severely calcified by visual assessment, or lesion prevents full pre-dilatation balloon expansion 11. Previous intervention restenosis 2. The target vessel contains visible thrombus 3. Another clinically significant lesion (>40%) is located in the same major epicardial vessel as the target lesion (including side branches) 4. Patient has a high probability that a procedure other than pre-dilatation and stenting and (if necessary) post-dilatation will be required at the time of index procedure for treatment of the target vessel (e.g. atherectomy, cutting balloon) 5. Target vessel was previously treated with any type of PCI < 6 months prior to index procedure 6. Non-Target vessel was previously treated with any type of PCI < 30 days prior to the index procedure
