Summary
Subvalvular aortic stenosis is a progressive left-sided obstructive lesion, usually consisting of a discrete membrane, fibromuscular ridge, or tunnel. Surgical intervention is preferred over catheter intervention when the gradient across the lesion is greater than 40 mm Hg or aortic insufficiency has developed across the aortic valve. Perioperative anesthetic goals include maintaining adequate preload, afterload, and a low to normal heart rate.
