Transcranial Doppler-Guided Resuscitation during Transcatheter Aortic Valve Replacement

Abstract

Introduction: Transcatheter aortic valve replacement (TAVR) has become an optimal substitute treatment for subjects with severe aortic stenosis who cannot undergo open chest surgery or who have a high surgical risk. Transcranial Doppler (TCD) provides monitoring of microembolic signals and cerebral blood flow during TAVR and detects ongoing fluctuations of intracerebral hemodynamics during each phase of the procedure.
