ObjectiveWe hypothesised that frailty assessment is of additional value to predict delirium and mortality after transcatheter aortic valve implantation (TAVI).MethodsObservational study in 89 consecutive patients who underwent TAVI. Inclusion from November 2012 to February 2014, follow-up until April 2014. Measurement of the association of variables from frailty assessment and cardiological assessment with delirium and mortality after TAVI, respectively.ResultsIncidence of delirium after TAVI: 25/89 (28%). Variables from frailty assessment protectively associated with delirium were: Mini Mental State Examination, (OR 0.79; 95% CI 0.65 to 0.96; p=0.02), Instrumental Activities of Daily Living (OR 0.79; 95% CI 0.63 to 0.99; p=0.04) and gait speed (OR 0.05; 95% CI 0.01 to 0.50; p=0.01). Timed Up and Go was predictively associated with delirium (OR 1.14; 95% CI 1.03 to 1.26; p=0.01). From cardiological assessment, pulmonary hypertension was protectively associated with delirium (OR 0.34; 95% CI 0.12 to 0.98; p=0.05). Multivariate logistic analysis: Nagelkerke R2=0.359, Mini Mental State Examination was independently associated with delirium. Incidence of mortality: 11/89 (12%). Variables predictively associated with mortality were: the summary score Frailty Index (HR 1.66, 95% CI 1.06 to 2.60; p=0.03), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II (HR 1.14, 95% CI 1.06 to 1.22; p<0.001) and complications (HR 4.81, 95% CI 1.03 to 22.38; p=0.05). Multivariate Cox proportional hazards analysis: Nagelkerke R2=0.271, Frailty Index and EuroSCORE II were independently associated with mortality.ConclusionsDelirium frequently occurs after TAVI. Variables from frailty assessment are associated with delirium and mortality, independent of cardiological assessment. Thus, frailty assessment may have additional value in the prediction of delirium and mortality after TAVI.

The EuroSCORE II, based on a recently updated database, reduces the overestimation of the calculated risk by the initial EuroSCORE. This difference is statistically significant and the EuroSCORE II may also reflect better current surgical performance.

BACKGROUND/OBJECTIVES Prospectively collected data on postoperative delirium (POD) after transcatheter aortic valve implantation (TAVI) are scarce. The aim of this study was to report the incidence and risk factors of delirium after TAVI under general anesthesia and to assess the association of POD with clinical outcome and short‐ and long‐term survival. DESIGN Prospective cohort study. SETTING Academic medical center. PARTICIPANTS A total of 703 subsequent patients undergoing TAVI under general anesthesia between 2008 and 2017. MEASUREMENTS Delirium was assessed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV), criteria. Outcomes were postprocedural clinical outcome and short‐ and long‐term survival (30 days and 5 years, respectively). RESULTS POD was observed in 16.5% (116/703), was the strongest independent predictor of long‐term mortality (hazard ratio = 1.91; 95% confidence interval [CI] = 1.36‐2.70), and was associated with impaired 30‐day and 5‐year survival (92.2% vs 96.8% [P = .025] and 40.0% vs 50.0% [P = .007], respectively). Stroke and new onset of atrial fibrillation were more often observed in delirious patients (6.9% vs 1.9% and 12.1% vs 5.1%, respectively). Strongest independent predictors of POD were prior delirium (odds ratio [OR] = 2.56; 95% CI = 1.52‐4.31) and aortic valve area less than 0.75 cm2 (OR = 2.39; 95% CI = 1.53‐3.74). CONCLUSION One in six patients experienced POD after TAVI under general anesthesia. POD was the strongest predictor of long‐term mortality and was associated with impaired short‐ and long‐term survival. Prior delirium and a more calcified aortic valve were the strongest independent predictors of POD. J Am Geriatr Soc 67:2325–2330, 2019

Intermediate to high-risk women enrolled in this first ever all-women contemporary TAVR registry experienced a 1-year VARC-2 composite efficacy endpoint of 16.5%, with a low incidence of 1-year mortality and stroke. Prior revascularization and EuroSCORE I were independent predictors of the VARC-2 efficacy endpoint, whereas EuroSCORE I, baseline atrial fibrillation, and prior percutaneous coronary intervention were independent predictors of the 1-year death or stroke.
