Dynamic aortic evaluation in planning thoracic endovascular aortic repair (TEVAR)
is important to provide optimal stent graft sizing. Static imaging protocols do
not consider normal aortic dynamics and may lead to stent graft to aorta
mismatch, causing stent graft related complications, such as type I endoleak and
stent graft migration. Dynamic imaging can assist in accurate stent graft
selection and sizing preoperatively, and evaluate stent graft performance during
follow-up. To create new imaging technologies, integration of knowledge between
diverse scientific fields is essential (i.e., engineering, informatics and
medicine). Different dynamic imaging modalities, such as
electrocardiographic-gated computed tomography angiography (ECG-gated CTA) and
four-dimensional phase-contrast MRI (4D PC-MRI), are progressively investigated
and implemented into clinical practice as important instruments in preoperative
planning for TEVAR. In time, further application of dynamic imaging tools for
preoperative screening and follow-up after TEVAR might lead to better outcomes
for patients. The advances in dynamic imaging for evaluation of the thoracic
aorta using new imaging modalities and their future perspectives are addressed in
this manuscript.
