Measurements of the mean systolic left ventricular-brachial artery gradient and cardiac output at rest and during exercise in four subjects with aortic stenosis were made in the course of combined right and left heart catheterization. Only minimal elevations were noted in the aortic systolic gradient during exercise despite significant flow increases in three of the four patients.
