Retrograde Percutaneous Coronary Intervention in a Case of Takayasu Arteritis with Left Main Coronary Artery Chronic Total Occlusion

<div>OCT images of PCI optimization. Initial OCT run showed diffuse neointimal hyperplasia with LMCA MSA of 1.93 m<sup>2</sup> (a). Final OCT run showed MSA at proximal LMCA and ostial LAD as 9.94 mm<sup>2</sup> and 10.01 mm<sup>2</sup>, respectively (b, c). OCT 3D bifurcation mode (ILUMIEN™ Optis™ System—Abbott Vascular) showed adequate LCX ostial area (d).</div>
