Role of Optical Coherence Tomography in Optimizing Percutaneous Coronary Intervention

Abstract

deliver balloon/stent the risk of in-stent (Fig. 1B) 6) . can accurately measure calcium thickness, calcium arc, and calcium length ; and accordingly can guide the selection of cutting balloon or rotational atherectomy. Also, OCT can accurately detects occurrence of calcium fracture following balloon angioplasty and thus predict adequate stent expansion. Maejima N. et al. concluded that the optimal thresholds for the prediction of calcium fracture Intravascular optical coherence tomography (OCT) is a recently developed technology that is becoming more and more increasingly available in the catheter laboratories. OCT is an easy and safe tool that can provide the operator with many valuable information aiding intervention and making the intervention safer and more predictable. OCT can guide all steps of intervention including target lesion assessment before intervention, stent selection, stent optimization, and post-stenting assessment. This review will summarize the role of OCT in guiding percutaneous coronary intervention.
