Exercise may artifactually increase computed aortic valve area in aortic stenosis; this Level 4 observation leaves open optimal assessment timing.
Does supine leg exercise alter hemodynamic parameters in patients with isolated valvular aortic stenosis?
In patients with isolated valvular aortic stenosis, exercise increases systolic aortic blood flow and pressure gradients, leading to an apparent increase in computed aortic valve area, while exercise-induced LVEDP changes correlate with age rather than stenosis severity.
Bache et al. (1971) studied this question.
