Angio-based 3DStent for evaluation of stent expansion

A 66-year-old male with diabetes, dyslipidaemia and arterial hypertension was referred because of Canadian Cardiovascular Society (CCS) class III stable angina, despite optimal medical treatment. Coronary angiography showed severe stenosis of the left circumflex artery, which was successfully treated during the index procedure with a drug-eluting stent, and of the left anterior descending artery (Moving image 1, Moving image 2), which was scheduled for staged percutaneous coronary intervention (PCI). Staged PCI consisted of predilatation and implantation of a 2.5x39 mm drug-eluting stent, which was postdilated in the proximal part with a 3.0x15 mm non-compliant (NC) balloon (Moving image 3). Stent expansion was evaluated by optical coherence tomography (OCT) (Moving image 4) and by 3DStent (GE HealthCare). 3DStent image acquisition was performed by a 200° rotational angiography with the balloon of the stent inside the implanted stent (Moving image 5). 3DStent images are shown as volume-rendering reconstruction (Figure 1A, Moving image 6) and as two orthogonal longitudinal views in which the operator may scroll to select a specific cross-section (Figure 1B, Figure...
