Frailty assessment and impact of frailty on outcomes after transcatheter aortic valve replacement.

Certain frail patients fail to achieve adequate functional or mortality benefit despite successful transcatheter aortic valve replacement (TAVR). Therefore, frailty assessment methods are becoming an important tool to identify and intervene on this high-risk patient subset for improving clinical outcomes. Areas covered: The authors provide an overview of frailty and frailty assessment tools being used in clinical practice and discuss the impact of frailty on the cardiac patients, particularly among the TAVR population. Expert commentary: Available evidence suggests that frailty assessment is critical for identifying patients at high risk of morbidity and mortality after TAVR procedures. However, there is lack of consensus for the best methodology to determine frailty and its optimal management in TAVR populations. Although, physical exercise is a commonly employed intervention to reduce frailty, a greater attention towards improving nutrition may convey more benefit than either intervention alone. Ongoing studies are investigating the benefits of a multicomponent approach to improve clinical outcomes in frail patients undergoing TAVR.
