Fractured Guidewire in Calcified Chronic Total Occlusion: Is Rotational Atherectomy Contraindicated?

Puntos clave

To evaluate the use of rotational atherectomy as a technique to address fractured guidewires during PCI for calcified CTOs.
Describes a case where a fractured guidewire was entrapped in a CTO during PCI.
Utilized rotational atherectomy to recanalize the CTO and ablate the guidewire fragment.
Monitored outcomes related to the procedure's safety and effectiveness.
Rotational atherectomy successfully recanalized the CTO.
The entrapped guidewire fragment was effectively ablated.
Demonstrates the viability of RA as a rescue option in such cases.

Resumen

Background: Fracture of guidewires may occur during attempts to recanalize severely calcified chronic total occlusions (CTOs) via percutaneous coronary intervention (PCI). When a fractured guidewire becomes entrapped within the lesion, rotational atherectomy (RA) may serve as a safe rescue strategy. Case: We report a case in which RA was utilized both to recanalize the heavily calcified CTO and to simultaneously ablate the entrapped guidewire fragment. Conclusions: RA may serve as a safe rescue strategy to manage the fractured guidewires within CTO segments.
