Purpose: To demonstrate the safety and feasibility of carotid artery stenting (CAS) in a patient with a continuous-flow left ventricular assist device (LVAD). Case Report: A 54-year-old woman with a LVAD was referred for a 90% stenosis of the right internal carotid artery (ICA). The patient was offered CAS, and oral anticoagulant was not discontinued in the periprocedural period. Because of absent arterial pulses, percutaneous transfemoral access was obtained under ultrasound guidance. Particular attention was paid to cannulation of the innominate artery; a 7-F guiding catheter was advanced from the descending aorta into the innominate artery under road-mapping, avoiding maneuvers in the ascending aorta where the outflow Dacron graft of the LVAD was anastomosed. To avoid cerebral flow modifications, the Angioguard RX was used as the cerebral protection device rather than other devices such as the flow reversal or flow-clamping systems. At this point, CAS was performed in a standard fashion using the 7×30-mm Precise ProRX stent. The computed tomography angiogram at 6 months showed patency of the stented right ICA. Conclusion: With adequate planning, CAS appears feasible in patients with a LVAD.

Abstract
Purpose: To demonstrate the safety and feasibility of carotid artery stenting (CAS) in a patient with a continuous-flow left ventricular assist device (LVAD). Case Report: A 54-year-old woman with a LVAD was referred for a 90% stenosis of the right internal carotid artery (ICA). The patient was offered CAS, and oral anticoagulant was not discontinued in the periprocedural period. Because of absent arterial pulses, percutaneous transfemoral access was obtained under ultrasound guidance. Particular attention was paid to cannulation of the innominate artery; a 7-F guiding catheter was advanced from the descending aorta into the innominate artery under road-mapping, avoiding maneuvers in the ascending aorta where the outflow Dacron graft of the LVAD was anastomosed. To avoid cerebral flow modifications, the Angioguard RX was used as the cerebral protection device rather than other devices such as the flow reversal or flow-clamping systems. At this point, CAS was performed in a standard fashion using the 7×30-mm Precise ProRX stent. The computed tomography angiogram at 6 months showed patency of the stented right ICA. Conclusion: With adequate planning, CAS appears feasible in patients with a LVAD.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
