Key result
Intracoronary imaging techniques such as IVUS, OCT, and NIRS allow for detailed longitudinal evaluation of bioresorbable scaffolds and the vessel wall to aid in improving their design and behavior.
Intracoronary imaging techniques such as IVUS, OCT, and NIRS are valuable for the detailed longitudinal evaluation of bioresorbable coronary scaffolds and their interaction with the vessel wall.
May guide scaffold design research; leaves open impact on clinical outcomes.
Various fully bioresorbable stents (BRS) have been recently developed, allowing for temporary scaffolding of the vessel wall. The potentially unique advantage of BRS to temporary scaffold the vessel could reduce the risk of adverse clinical outcomes caused by acute vessel geometry changes, late malapposition, jailed side branches or inflexibility of permanent stents. The design of BRS is, however, not similar for all stents, resulting in differences in degradation and behaviour. To assess the performance of BRS, the effect of degradation and behaviour on the vessel wall should be accurately evaluated. Intracoronary imaging techniques such as intravascular ultrasound (IVUS), optical coherence tomography (OCT) and near-infrared spectroscopy (NIRS) allow for detailed longitudinal evaluation of the stent and the vessel wall and might therefore aid in improving design and behaviour of BRS.
