Optical coherence tomography (OCT) has become the invasive imaging modality of choice for coronary stent assessment due to its unmatched spatial resolution. Neointimal calcification (NC) is a rare finding, observed in 5-10% of in-stent restenosis (ISR) neointima. The impact of NC on percutaneous coronary intervention of ISR is unknown. We therefore present the outcome of six unique cases of ISR and NC in which OCT was used to evaluate the impact of NC on the quality of stent-in-stent deployment for the treatment of ISR. This series demonstrates for the first time the impact of NC on stent expansion, a finding which might help guiding percutaneous coronary intervention for ISR with NC.
光学相干断层扫描（OCT）因其无与伦比的空间分辨率，已成为冠状动脉支架评估的侵入性成像方式。新生内膜钙化（NC）是一种罕见的发现，在5%-10%的支架内再狭窄（ISR）新生内膜中可见。NC对ISR经皮冠状动脉介入治疗的影响尚不清楚。因此，我们展示了6例ISR合并NC的独特病例的结果，其中使用OCT评估NC对用于治疗ISR的支架内支架置入质量的影响。该系列首次证明了NC对支架扩张的影响，这一发现可能有助于指导对合并NC的ISR进行经皮冠状动脉介入治疗。
