Stent underexpansion is a major contributing factor to stent failure, be that restenosis or stent thrombosis. Intracoronary imaging is increasingly being used to optimise the results of percutaneous coronary intervention (PCI) and has been shown to decrease the rate of underexpansion. However, optimal imaging-defined expansion criteria vary across studies. Furthermore, the correlation between these expansion criteria and the physiological results of stenting have not been extensively investigated.
In this issue of EuroIntervention, Belguidoum and colleagues present a post hoc analysis of the optical coherence tomography (OCT) cohort of the DOCTORS study1.
The DOCTORS study randomised non-ST-elevation acute coronary ...
