case_images: Cardio Ankle Vascular Index and its derived pulse wave morphology in aortic valve stenosis. A print of the original cardio ankle vascular index (CAVI) measurement, before and after surgical valve replacement (AVR). The pulse wave morphology was enlarged without changing the ratio of the picture. To highlight the change of the slope of the upstroke of the pulse, a blue line was inserted for the upstroke angle before AVR, and an Orange line was inserted for the upstroke angle after AVR.

case_images: Before surgery, CAVI was 4.7 (average of left and right CAVI) with an ejection time of 386ms (Figure 1). Finally, the morphology of the brachial pulse wave changed after the relief of the left ventricular obstruction to a steeper upstroke signal compared to a prolonged and flattened pattern before (Figure 1).
