ABSTRACT
A 64-year-old man presented with previous non-ST elevation myocardial infarction and cardiogenic shock. Due to hemodynamic instability, percutaneous coronary intervention (PCI) was performed with implantation of two everolimus-eluting stents by V-stenting technique to LM-LAD and LM-LCX. After 9 months without symptoms, he developed progressive angina. Non-selective LM coronary angiography was performed due to stents protrusion in the aortic root. A 128-slice dual-source coronary CT angiography showed severe LM-LAD stent underexpansion with critical in-stent restenosis at the proximal third. Two days later, selective angiography and optical coherence tomography depicted stent underexpansion and confirmed the in-stent restenosis. This case is illustrative of the potential role of the complementary use of invasive and non-invasive imaging techniques. The coronary CT angiography was very useful to identify the severity and mechanism of restenosis, and thus guiding the PCI procedure in a case of especially difficult catheterization.
