Symptomatic severe aortic stenosis is a serious life-threatening condition that requires surgical intervention. Until recently, the only available treatment options were through an open-heart surgery technique. A transcatheter aortic valve replacement is a minimally invasive aortic valve replacement procedure that is available for symptomatic patients with severe aortic stenosis and who are considered high-risk surgical candidates. It is an effective procedure for individuals with multiple comorbidities and high risk for mortality. This article reviews aortic stenosis and associated morbidity and mortality, treatment options, complications, education, and implications.
