Transcarotid arterial revascularization (TCAR) with flow reversal offers a less invasive option for carotid revascularization in high-risk surgical patients. TCAR has been shown to have similar complication rates for stroke and mortality compared with carotid endarterectomy and lower complication rates compared with transfemoral carotid artery stenting. A relative contraindication for carotid stenting includes heavily calcified lesions. Intravascular lithotripsy has been approved for use in other vascular beds for endovascular treatment of heavily calcified lesions. In the present report, we have demonstrated the application of intravascular lithotripsy for heavily calcified carotid lesions, enabling treatment with TCAR for those who otherwise might be at high risk of transfemoral carotid artery stenting or carotid endarterectomy.
