Aortic stenosis: From diagnosis to treatment: A review (2021 update)

As the aging population increases, a concurrent rise in the incidence of aortic stenosis (AS) is projected. Early recognition and diagnosis of AS are cardinal in preventing the progression of the disease into its more fatal effects. Precision in diagnosis and risk stratification is paramount, as therapy can be opted accordingly. Current therapeutic advances aim to target an elderly population with minimally invasive procedures such as transcatheter aortic valve replacement (TAVR), transforming conventional management in a more at-risk population. Despite dismal outcomes without treatment, therapy in the form of surgical aortic valve replacement or TAVR is proven to improve survival in cases of AS, with such therapeutic benefit being observable at the extreme end of the spectrum with inoperable cases. In this review, we will address the latest recommendations and guidelines on AS, with emphasis on diagnosis and treatment.
