Evaluation of Changes in Functional Status in the Year After Aortic Valve Replacement

In this prospective single-institution study, functional status trajectory one year after intervention was compared for transcatheter (TAVR) versus surgical aortic valve replacement (SAVR).  A moderate/large decline compared to preintervention status occurred in 23% of TAVR patients and 4% of SAVR patients.  A frailty index, postoperative delirium, and procedure-related complications were associated with postintervention decline.
