Rotational Atherectomy Is Trending Again: The Precision Play for Calcified Coronary PCI
Percutaneous transluminal coronary rotational atherectomy is back in the spotlight because the case mix in PCI is changing. As populations age and more patients present with diabetes, chronic kidney disease, and prior stents, operators are encountering heavily calcified coronary lesions that resist balloon expansion and limit stent deliverability. In these moments, rotational atherectomy becomes a precision tool: it modifies calcium to restore vessel compliance so definitive therapy can be deployed predictably, rather than forcing hardware through an unprepared segment.
The clinical conversation has moved beyond “can we cross?” to “can we optimize?” Success depends on strategy and discipline: careful lesion assessment, appropriate burr sizing, short controlled runs that avoid thermal injury, and vigilant management of slow-flow or spasm. Just as important is integration with contemporary imaging and physiology. Intravascular imaging clarifies calcium arc and thickness, guides atherectomy intensity, and confirms adequate modification before stenting. When teams align technique with imaging, they reduce underexpansion risk, improve acute luminal gain, and increase confidence that the final result will endure.
For decision-makers, the opportunity is operational as much as technical. Building a reliable atherectomy program requires standardized protocols, simulation-based training, and cath lab readiness for hemodynamic support in complex patients. It also demands clear criteria for when to escalate from balloons or other calcium-modifying options to rotational atherectomy. The organizations that invest in these pathways will treat more complex disease safely, expand PCI capability, and deliver consistent outcomes in the era of calcified coronary artery disease.
