Left Main PCI in Severely Calcified Lesions
Percutaneous coronary intervention of the unprotected left main coronary artery remains one of the most challenging scenarios in interventional cardiology, particularly in the presence of severe coronary calcification, which may compromise device deliverability, optimal stent expansion, and adequate stent apposition.
In this setting, plaque modification techniques, particularly rotational atherectomy, play a pivotal role in lesion preparation by modifying calcified plaque and improving vessel compliance.
This case ulstrates the value of rotational atherectomy in optimizing lesion preparation in complex calcified left main disease, enabling optimal stent deployment and favorable procedural outcomes.
