Answer

Radionuclide studies to evaluate myocardial perfusion at rest and during exertion and exercise may be considered as part of the complete workup of aortic stenosis. Radionuclide ventriculography may provide information on LV function, including LVEF, ESV, and EDV. Perform these tests cautiously on symptomatic patients. [23]
