Data on patients with diabetes who were treated for aortic stenosis revealed those who underwent transcatheter aortic valve replacement had lower rates of all-cause mortality and renal failure at one year than those treated with surgery, although the difference in mortality disappeared after two years. "[A] less invasive method of valve replacement that avoids the injurious effects of cardiopulmonary bypass may lead to improved clinical outcomes among these high-risk patients with diabetes," researchers wrote in the Journal of the American College of Cardiology.
