Delirium After TAVR: Crosspassing the Limit of Resilience
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
Prognostic Value of Preprocedural LVÂ Global Longitudinal Strain for Post-TAVR-Related Morbidity and Mortality: A Meta-Analysis
BACKGROUND
Left ventricular ejection fraction (LVEF) demonstrates limited prognostic value for post-transcatheter aortic valve replacement (TAVR) outcomes. Evidence regarding the potential role of left ventricular global longitudinal strain (LV-GLS) in this setting is inconsistent.
OBJECTIVES
The aim of this systematic review and meta-analysis of aggregated data was to evaluate the prognostic value of preprocedural LV-GLS for post-TAVR-related morbidity and mortality.
METHODS
The authors searched PubMed, Embase, and Web of Science for studies investigating the association between preprocedural 2-dimensional speckle-tracking-derived LV-GLS and post-TAVR clinical outcomes. An inversely weighted random effects meta-analysis was adopted to investigate the association between LV-GLS vs primary (ie, all-cause mortality) and secondary (ie, major cardiovascular events [MACE]) post-TAVR outcomes.
RESULTS
Of the 1,130 identified records, 12 were eligible, all of which had a low-to-moderate risk of bias (Newcastle-Ottawa scale). On average, 2,049 patients demonstrated preserved LVEF (52.6% ± 1.7%), but impaired LV-GLS (-13.6% ± 0.6%). Patients with a lower LV-GLS had a higher all-cause mortality (pooled HR: 2.01; 95% CI: 1.59-2.55) and MACE (pooled odds ratio [OR]: 1.26; 95% CI: 1.08-1.47) risk compared with patients with higher LV-GLS. In addition, each percentage point decrease of LV-GLS (ie, toward 0%) was associated with an increased mortality (HR: 1.06; 95% CI: 1.04-1.08) and MACE risk (OR: 1.08; 95% CI: 1.01-1.15).
CONCLUSIONS
Preprocedural LV-GLS was significantly associated with post-TAVR morbidity and mortality. This suggests a potential clinically important role of pre-TAVR evaluation of LV-GLS for risk stratification of patients with severe aortic stenosis.
