Moderate chronic kidney disease and left ventricular hypertrophy after aortic valve replacement for aortic valve stenosis.

Objective: Left ventricular hypertrophy regression is assumed to be one of the most important goals after aortic valve replacement for aortic stenosis. A moderate decrease in the glomerular filtration rate is associated with a significantly increased risk of left ventricular hypertrophy in hypertensive patients. The effect of moderate kidney disease on left ventricular hypertrophic remodeling in other conditions of chronic left ventricular pressure overload, such as aortic stenosis, remains unknown. Therefore we tested the hypothesis that moderate chronic kidney disease affects left ventricular mass regression in patients undergoing isolated aortic valve replacement for aortic stenosis. Methods: In 157 patients with aortic stenosis, left ventricular mass regression was assessed at 18 months after aortic valve replacement. Among them, 73 (46%) had a moderate chronic kidney disease (glomerular filtration rate between 60 and 30 mL/min per 1.73 m2). Patients with severely impaired kidney function (glomerular filtration rate of
