Abstract
Aortic stenosis (AS) is the most frequent valvular heart disease in western industrialized countries. AS is caused by age related degenerative calcific disease. The mechanism is believed to be similar to that of atherosclerosis. The treatment of symptomatic AS is surgical replacement of the aortic valve. Medical treatment is often utilized in optimizing patients before surgery but has limited utility in treating symptoms. Transcatheter aortic valve replacement (TAVR) has become an established treatment for symptomatic severe AS. Careful patient selection, valve sizing, and meticulous technique result in good outcomes. Palliative management of symptomatic AS was appropriate for patients who were not candidates for aortic valve surgery. This new approach is discussed in this chapter.
