Transverse partial stent ablation with rotational atherectomy for suboptimal culotte technique in left main stem bifurcation

Keywords: coronary intervention; optical coherence tomography; rotational atherectomy


Longitudinal rotational atherectomy of metal struts is well described as bail-out strategy to treat undilatable instent restenosis. Ablation of metal stent struts jailing the ostium of a major side branch in a coronary bifurcation is not described. In the current report, we describe a case of "transverse" rotational atherectomy to treat a failure of culotte stenting in a left main stem bifurcation. We document for the first time in vivo and in man the effect of this strategy using optical coherence tomography.
