Aortic valve replacement is the most commonly performed valve operation. It has been shown to be an effective therapy in all age groups, including the very elderly (age > 90 years). The most common etiologies for aortic stenosis are calcific degeneration, rheumatic disease, and congenital bicuspid valves. The most common causes of pure aortic regurgitation include annuloaortic ectasia and associated dilation of the aortic root, endocarditis, aortic dissection, and rheumatic disease. The indications for surgery depend on the pathophysiology and symptoms. The choice of the prosthesis can be difficult and depends on multiple clinical and lifestyle considerations. Early and late outcomes are generally quite good, even in high-risk patients.
