Optical coherence tomography and intravascular ultrasound of double kissing crush coronary bifurcation stenting

摘要

A 55-year-old male underwent percutaneous coronary intervention (PCI) of a Medina 1,1,1 circumflex (LCx) and a first obtuse marginal (OM1) bifurcation lesion. A double kissing crush technique was performed, utilising a 2.75x12 mm everolimus-eluting stent (EES) in OM1 and a XIENCE V~R 4.0x15 mm EES (Abbott Vascular, Santa Clara, CA, USA) in the LCx (Online Figure 1). Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) runs were performed (Online Figure 2, Oniine Figure 3, Moving image 1). 3D reconstruction of the OCT further clarified the reconstruction of the bifurcation carina and paving, in particular in the crushed segment. Quantitative analysis showed only 10/327 struts to be malapposed (Figure 1, Moving image 2). We demonstrated the utility of OCT imaging in a complex bifurcation intervention.
