Prediction of Post-stenting Lumen Dimensions Using High-Definition Intravascular Ultrasound
- development and validation of a patient-specific HD IVUS-based computational framework
Authors' conclusion
We presented and validated a patient-specific computational simulation framework that uses high-resolution intracoronary imaging of plaque components to precisely predict the lumen dimensions post-stenting.
Study context
- Population
- Patients who underwent HD IVUS and coronary angiography before and after stenting
- Participants
- Nine patients
- Comparison
- post-simulation lumen dimensions were compared with the actual post-stenting HD IVUS lumen dimensions

Stent geometry assessed by eccentricity
- Predicted stent geometry showed high agreement with HD IVUS-derived stent shape
Stent apposition
- Stent apposition was accurately predicted by the computational simulations
