Cine loops of pulse wave propagation for the mice in Figure 1 show the abdominal aortas of (a) a normal mouse with no AAA disease, (b) a mouse with a stable aneurysm, and (c) a mouse with an unstable aneurysm that ruptured between 18 and 20 days after the start of angiotensin II infusion. The color overlay on the B-mode images represents the axial wall displacement induced by the pulse wave, while the time stamp in each frame indicates the time elapsed since the start of the cardiac cycle (ie, the R wave of the ECG signal).
