Abstract
Patients with severe aortic stenosis are commonly elderly and with significant comorbidity. Surgical intervention can improve symptoms and survival in severe aortic stenosis. However, a large proportion of patients do not undergo surgical intervention because they are deemed to be inoperable or too high risk. Over the last decade, transcatheter aortic valve replacement (TAVR) has been developed, providing an effective, less-invasive alternative to open cardiac surgery for inoperable or high-risk patients. The purpose of this review is to provide an overview of risk assessment in TAVR. Specifically, this article reviews the epidemiology of aortic stenosis, describes the risks and benefits of TAVR across multiple outcome measures, explores frailty and other elderly risk factors as metrics for improved risk assessment and discusses the application of improved risk assessment in TAVR decisions.
