    In Vivo Flow Simulation at Coronary Bifurcation Reconstructed by Fusion of 3-Dimensional X-ray Angiography and Optical Coherence Tomography [Images and Case Reports in Interventional Cardiology

    High-quality reconstruction of coronary bifurcations is crucial in the evaluation of lesions, dedicated bifurcation stents, and stent techniques. Although 3-dimensional (3D) X-ray angiography restores natural bending of vascular structures, optical coherence tomography (OCT) provides an ultra–high resolution of the vessel wall morphology and stents at baseline and follow-up. We present a new method for 3D fusion of the 2 imaging modalities combined with flow simulation at the target bifurcation. A 63-year-old woman was admitted for percutaneous coronary intervention attributable to severe stenosis (Figure 1A) in the left anterior descending artery (LAD) at the bifurcation of the first diagonal branch ...
