Angiography-derived fractional flow reserve versus intravascular ultrasound to guide percutaneous coronary intervention in patients with coronary artery disease (FLAVOUR II): a multicentre, randomised, non-inferiority trial. Revascularisation decisions based on angiography-derived fractional flow reserve (FFR) or optimisation of stent implantation with intravascular ultrasound yield superior clinical outcomes compared with percutaneous coronary intervention (PCI) guided by angiography alone. However, the differences in outcomes when a single approach is used for both purposes remain unclear. We aimed to assess the non-inferiority of angiography-derived FFR versus intravascular ultrasound guidance in terms of clinical outcomes at 12 months in patients with angiographically significant

Experimental validation and clinical feasibility of 3D reconstruction of coronary artery bifurcation stents using intravascular ultrasound. The structural morphology of coronary stents and the local hemodynamic environment following stent deployment in coronary arteries are crucial determinants of procedural success and subsequent clinical outcomes. High-resolution intracoronary imaging has the potential to facilitate geometrically accurate three-dimensional (3D) reconstruction of coronary stents. This work presents an innovative algorithm for the 3D reconstruction of coronary artery stents, leveraging intravascular ultrasound (IVUS) and angiography. The accuracy and reproducibility of our method were tested in stented patient-specific silicone models, with micro-computed tomography serving

Intravascular ultrasound-guided versus angiography-guided percutaneous coronary intervention in acute coronary syndromes (IVUS-ACS): a two-stage, multicentre, randomised trial. Intravascular ultrasound-guided percutaneous coronary intervention has been shown to result in superior clinical outcomes compared with angiography-guided percutaneous coronary intervention. However, insufficient data are available concerning the advantages of intravascular ultrasound guidance for patients with an acute coronary syndrome. This trial aimed to investigate whether the use of intravascular ultrasound guidance, as compared with angiography guidance, improves the outcomes of percutaneous coronary intervention with contemporary drug-eluting stents in patients presenting with an acute coronary syndrome

Fractional flow reserve- and intravascular ultrasound-guided strategies for intermediate coronary stenosis and low lesion complexity in patients with or without diabetes: a post hoc analysis of the randomised FLAVOUR trial.

Intravascular Ultrasound-Guided vs Angiography-Guided Drug-Coated Balloon Angioplasty in Patients With Complex Femoropopliteal Artery Disease. Intravascular ultrasound (IVUS) guidance has been shown to yield favorable outcomes for endovascular treatment of femoropopliteal artery (FPA) disease with drug-coated balloon (DCB) angioplasty. However, the specific benefits of IVUS for treatment ; P = 0.44) or occurrence secondary endpoints between the IVUS-guidance and angiography-guidance groups for patients with noncomplex FPA. In endovascular treatment of FPA using DCB, IVUS guidance was significantly associated with improved 12-month clinical outcomes, particularly in patients with complex FPA lesions.(Intravascular Ultrasound-Guided Drug-Coated Balloon Angioplasty for Femoropopliteal

Intravascular Ultrasound Predictors of 12-month Patency Loss Following Drug-Coated Balloon Angioplasty for the Femoropopliteal Artery. Intravascular ultrasound (IVUS) has been shown to improve outcomes of drug-coated balloon (DCB) angioplasty for treatment of femoropopliteal artery (FPA) disease. However, the optimal IVUS criteria for achieving improved outcomes of DCB angioplasty for FPA

Continuous extracorporeal femoral perfusion model for intravascular ultrasound, computed tomography and digital subtraction angiography. We developed a novel human cadaveric perfusion model with continuous extracorporeal femoral perfusion suitable for performing intra-individual comparison studies, training of interventional procedures and preclinical testing of endovascular devices. Objective of this study was to introduce the techniques and evaluate the feasibility for realistic computed tomography angiography (CTA), digital subtraction angiography (DSA) including vascular interventions, and intravascular ultrasound (IVUS). The establishment of the extracorporeal perfusion was attempted using one formalin-fixed and five fresh-frozen human cadavers. In all specimens, the common femoral

Optical Coherence Tomography-Guided or Intravascular Ultrasound-Guided Percutaneous Coronary Intervention: The OCTIVUS Randomized Clinical Trial Intravascular imaging-guided percutaneous coronary intervention (PCI) with intravascular ultrasound (IVUS) or optical coherence tomography (OCT) showed superior clinical outcomes compared to angiography-guided PCI. However, comparative effectiveness

Prognostic Implications of Quantitative Flow Ratio and Plaque Characteristics in Intravascular Ultrasound-Guided Treatment Strategy. Quantitative flow ratio (QFR) is a method for evaluating fractional flow reserve without the use of an invasive coronary pressure wire or pharmacological hyperemic agent. The aim of this study was to investigate the prognostic implications of QFR and plaque characteristics in patients who underwent intravascular ultrasound (IVUS)-guided treatment for intermediate lesions. Among the IVUS-guided strategy group in the FLAVOUR (Fractional Flow Reserve and Intravascular Ultrasound for Clinical Outcomes in Patients with Intermediate Stenosis) trial, vessels suitable for QFR analysis were included in this study. High-risk features were defined as low QFR (≤0.90
