[When orbital exceeds its limits!]

Abstract

High calcified PCI are challenging because immediate and follow-up results are not optimal. We recommend using a specific preparation of these lesions, especially using atherectomy which can itself provide complications. We illustrate our comments with a clinical case where we have decided to treat a long-calcified lesion from left main to distal left artery descending with a specific preparation according orbital atherectomy. Procedure was complicated by a coronary perforation with favorable evolution. This case allows to report how to prevent a such complication and to remember how should we have to treat it.
