Successful Orbital Atherectomy of Left Main Bifurcation Lesion Using Microcatheter Protection of Nonatherectomy Wire

-Optimal PCI may be challenging with calcified left main bifurcation lesions-Orbital atherectomy is a common strategy for lesion optimization-Side branch occlusion feared complication of orbital atherectomy-Utilizing microcatheter wire protection can minimize risk Corrigendum to “Successful Orbital Atherectomy Left Main Bifurcation Lesion Using Microcatheter Protection Nonatherectomy Wire”Journal the Society Cardiovascular Angiography & InterventionsVol. 1Issue 3100030PreviewFollowing publication, it was noted that several panels Figure 1 included contouring in IVUS images.
