Figure 5: Low-dose dobutamine stress echocardiography data of Case C, a case of CR − ve classical low-flow low-gradient aortic stenosis. Aortic valve area in square centimeter (Y-axis) plotted against transvalvular flow rate in ml/s (X-axis) for each stage of low-dose dobutamine stress echocardiography
