©2013 UpToDate ® Print Email Survival after aortic valve replacement in aortic stenosis with left ventricular dysfunction Kaplan-Meier survival curves show that patients with aortic stenosis and left ventricular dysfunction who undergo aortic valve replacement have a survival which is similar to that expected in the overall population in the absence of significant coronary artery disease (CAD, defined as ≥2 vessel disease or left main disease). In contrast, survival is reduced when significant CAD is present. Data from Connolly HM, Oh JK, Orszulak TA, et al. Circulation 1997; 95:2395.
