The delivery of the rotational atherectomy burr can sometimes be hindered in distal calcified lesions complicated by proximal vessel tortuosity or other obstacles. This problem may result procedural failure fatal complications, including coronary perforation, entrapment, driveshaft fracture. To prevent these catastrophic outcomes and ensure successful delivery, we introduce DELIVER (Deep Engagement guide catheter 5-F chiLd-guIde for deliVEry subsequent Rotational atherectomy) technique. method involves deep insertion beyond obstacles, using strategies such as balloon anchoring Once is positioned, advanced through it to facilitate target lesion. report presents 3 cases where technique was applied successfully treat lesions. enabled smooth atraumatic even tortuous arterial segments challenging anatomical structures.
