Predictors of target lesion revascularisation after drug-eluting stent implantation for calcified nodules: an optical coherence tomography study.

ABSTRACT:

Background

Evidence of prognostic factors for stent failure after drug-eluting stent implantation for calcified nodules (CNs) is limited.

Aims

We aimed to clarify the prognostic risk factors associated with stent failure among patients who underwent drug-eluting stent implantation for CN lesions using optical coherence tomography (OCT).

Methods

This retrospective, multicentre, observational study included 108 consecutive patients with CNs who underwent OCT-guided percutaneous coronary intervention (PCI). To evaluate the quality of CNs, we measured their signal intensity and analysed the degree of signal attenuation. All CN lesions were divided into dark or bright CNs according to the half width of signal attenuation, greater or lower than 332, respectively.
