Cardiovascular diseases (CVD) causes 17.7 million deaths globally every year and aortic aneurysm is a key contributor. Aortic aneurysms typically occur in the abdominal aorta, and but can also occur in the descending aorta. The Frozen Elephant Trunk stent (FET) is one of the leading treatments for the aneurysms of the aorta, extending into the descending aorta. This presentation focuses on the in-vitro experimentation of a stented descending aorta, investigating the haemodynamics in a compliant phantom. A silicone phantom of the descending aorta and PVC stent was manufactured using a lost core casting method. Particle imaging velocimetry (PIV) was used to visualise the flow for pulsatile conditions, focusing specifically on the passive fixation at the distal end of the FET where the stent it known to fail on occasion. The results of this investigation are still ongoing with post-processing to be carried out.
