Aortic Stenosis

Purpose of Review: Aortic stenosis is the most prevalent valvular heart disease. The purpose of this paper is to review the epidemiology, pathophysiology, and diagnosis of aortic valve stenosis. Recent Findings: The diagnosis of aortic stenosis has evolved over time. Originally diagnosed with cardiac catheterization and echocardiography, more advance imaging techniques including computed tomography, magnetic resonance imaging, and 3D printing have improved our understanding of the physiology and hemodynamic effects of aortic stenosis. Summary: Valvular heart disease affects a broad patient population, and the most common form of severe valve dysfunction is aortic valve stenosis. It is important to understand the prevalence of the disease and the pathophysiology of aortic stenosis. Both traditional and modern imaging modalities are used to accurately identify aortic stenosis, to define the severity, and to select patients best suited for valve replacement therapy.
