Physiologic Compensation Is Supranormal in Compensated Aortic Stenosis: Does it Return to Normal After Aortic Valve Replacement or Is it Blunted by Coexistent Coronary Artery Disease?

Abstract

In AS patients after AVR, reverse remodeling of the supranormal systolic function parallels improvement in cardiovascular MRI-derived regression of LV hypertrophy and LV intramyocardial strain. However, discordant effects are evident after AVR, driven by CAD status, suggesting that the typical AVR benefits are experienced disproportionately by those without CAD and not by those obliged to undergo concomitant coronary artery bypass grafting/AVR.
