 The purpose of the study is to see if statin therapy will optimize myocardial response to cardiopulmonary bypass during aortic valve replacement AVR for aortic valve stenosis AVS Phase I and optimize left ventricular reverse remodeling following AVR Phase II. Preliminary evidence indicates that perioperative statin therapy reduce mortality and morbidity following cardiac surgery. Pleiotropic effects of statins may induce myocardial preconditioning and optimize myocardial and systemic responses to cardiopulmonary bypass during AVR. Furthermore statin therapy after AVR may contribute to an optimal left ventricular reverse remodeling.
