A substantial proportion of patients submitted to transcatheter aortic valve replacement (TAVR) continues to be affected by procedure-related neurological events, with 30-day clinical stroke rates in the range of 4-7%. Also, routine neuroimaging studies reveal that ischaemic cerebral infarction caused by showers of cerebral emboli during valve instrumentation and placement affect virtually all patients undergoing TAVR1,2,3.
