Filter neuroprotection of a single patent internal carotid artery during transapical aortic valve implantation

The finding of a mobile calcific plaque attached to the aortic valve cusp during transcatheter aortic valve implantation (TAVI/TAVR) necessitated utilization of an embolic protection device, for cerebral protection. We report the urgent but successful deployment of such a filter in a patient with a single patent internal carotid artery. Although stroke rates observed in first-generation TAVI trials were higher than those reported following conventional open aortic valve replacement, adjunctive neuroprotective measures, particularly in patients with a large amount of threatened cerebral territory, may minimize potential neurologic injury.
