ABSTRACT
					
	Patients who undergo transcatheter aortic valve replacement often are 
frail and elderly. Delirium is a frequently observed complication, 
associated with impaired recovery, prolonged hospital stay, and 
mortality. In different hospital settings, interventions that reduced 
the incidence of delirium resulted in improved clinical outcome and 
reduced costs. In that context, prevention, early recognition, and 
timely interventions could be the next step toward better outcomes of 
transcatheter aortic valve replacement. This review is focused on 
awareness and recognition of delirium, including predisposing 
“vulnerability” factors (such as cognitive impairment and carotid artery
 disease) and “trigger” factors (such as anesthesia, hemodynamic 
imbalance, and complications). For prevention and treatment, clinicians 
should focus on sleep hygiene, orientation, pain management, and early 
mobilization. In case of delirium, a thorough search and treatment of 
trigger factors is warranted. Future studies should focus on risk 
assessment, preventive and therapeutic interventions, and their 
potential benefit in terms of costs and clinical outcomes.
