Coronary Orbital Atherectomy Through Newly Deployed Left Main Coronary Stent.

Percutaneous coronary intervention (PCI) in complex, calcified coronary lesions can be assisted with orbital atherectomy (OA). OA is generally avoided when there are lesions amendable to OA distal to a newly deployed stent due to the risk of device-stent interaction, burr entrapment, and stent avulsion. We present a case documenting the successful passage of an OA system through a recently deployed left main stent to prepare a chronically occluded left anterior descending for PCI.
