Study Arms (1)
Calcified Carotid Artery
EXPERIMENTALUp to 160 subjects with calcified carotid arteries to be treated with intravascular lithotripsy (IVL) prior to stenting with commercially available trans-carotid stent systems in patients at high risk for complications from carotid endarterectomy (CEA) will be enrolled in the study.
Interventions
The Shockwave Medical Intravascular Lithotripsy (IVL) System with the Shockwave SkyRunner Carotid IVL Catheter is intended for lithotripsy- enhanced balloon dilatation of ≥ 3 mm thick calcified lesions in the carotid arteries prior to stenting. Not for use for treating massive exophytic (mushroom-like) or irregular endoluminal carotid calcification, or in the coronary or cerebral arteries.
Eligibility Criteria
You may qualify if:
- Age ≥ 18 years.
- Patient is able and willing to comply with all assessments in the study.
- Patient has been informed of the nature of the study, agrees to participate and has signed the approved informed consent form.
- Patient must have a life expectancy \> 1 year at the time of the index procedure with no planned major cardiac intervention or surgery within 30 days following the index procedure.
- Patient has a discrete lesion located in the internal carotid artery (ICA) with or without involvement of the carotid bifurcation.
- Target lesion must meet all requirements for commercially available trans-carotid stent systems (refer to IFU for requirements) and investigator intends to treat the target lesion with a single stent.
- Patient must meet one of the following criteria regarding neurological symptom status and degree of stenosis by duplex ultrasound in combination with CT or MR angiography:
- Symptomatic: ≥ 50% stenosis of the internal carotid artery and the patient has a history of stroke, TIA and/or amaurosis fugax within 180 days of the procedure ipsilateral to the carotid artery to be treated.
- Asymptomatic: ≥ 70% stenosis of the internal carotid artery without any neurological symptoms.
- Patient has evidence of circumferential calcification of the stenotic lesion defined as ≥ 3 mm thickness of calcification as determined by Computed Tomography Angiography (CTA).
- Patient is high risk for CEA defined as meeting at least one anatomic or clinical high-risk condition listed below:
- Contralateral Carotid artery occlusion.
- Tandem Stenoses \> 70%.
- High cervical carotid artery stenosis.
- Restenosis after carotid endarterectomy.
- +15 more criteria
You may not qualify if:
- Patient has alternative source of cerebral embolus, including but not limited to:
- a history of chronic atrial flutter or atrial fibrillation, or paroxysmal atrial flutter or atrial fibrillation requiring chronic anticoagulation
- knowledge of cardiac sources of emboli (e.g., left ventricular aneurysm, intracardiac filling defect, cardiomyopathy, aortic or mitral prosthetic heart valve, hemodynamically significant aortic stenosis, endocarditis, mitral stenosis, or left atrial myxoma)
- recently (\< 60 days) replaced/repaired heart valve (either surgically or percutaneously).
- Patient has a history of spontaneous intracranial hemorrhage within the past 12 months, a hemorrhagic transformation of an ischemic stroke within the past 60 days or has had a recent stroke (\< 7 days) of sufficient size (on CT or MRI) to place the patient at risk of hemorrhagic conversion during the procedure.
- Patient with a history of major stroke with substantial neurological deficit (NIHSS ≥ 5 or mRS ≥ 3) within 1 month of index procedure.
- Patient has had a TIA, or amaurosis fugax within 48 hours prior to the procedure.
- Patient has neurologic illnesses within the past 2 years characterized by fleeting or fixed neurologic or cognitive deficit which cannot be distinguished from TIA or stroke.
- Patient has an intracranial tumor.
- Patient has an isolated hemisphere.
- Patient has an open stoma in the neck.
- Patient has an unresolved/uncorrected bleeding disorder.
- Patient had a myocardial infarction (MI) within last 72 hours prior to index procedure.
- Patient has contralateral laryngeal, lateral recurrent, or vagus nerve injury.
- Patient has history of intolerance or allergic reaction to contrast material that cannot be adequately premedicated or to any of the required study medications (i.e., antiplatelet agents, statins) or device materials (refer to IFUs).
