Once a patient with aortic stenosis becomes symptomatic, aortic valve replacement should be performed as long as the patient can tolerate surgery and has no co-morbidities. If severe left ventricular dysfunction is present in the setting of aortic stenosis, it is of utmost importance to differentiate between true severe aortic stenosis and pseudo-severe aortic stenosis as these two entities have different pathophysiologies and different outcomes after aortic valve replacement.
Medical therapy reduces symptoms but does not prolong life. If a patient has extensive co-morbidities, transcatheter aortic valve implantation can be considered.  Aortic valvuloplasty can be considered in those patients who are too sick for surgery or transcatheter aortic valve implantation.
