When absence of evidence equates to evidence of absence: the case of routine use of cerebral embolic protection devices in transcatheter aortic valve implantation

Current-generation CEP devices are ineffective in reducing periprocedural TAVI-stroke risk to a clinically relevant degree, rendering future trials with these devices futile.
Study context
