Despite advances in technology, percutaneous coronary intervention (PCI) of severely calcified coronary lesions remains challenging. Rotational atherectomy is one of the current therapeutic options to manage calcified lesions, but has a limited role in facilitating the dilation or stenting of lesions that cannot be crossed or expanded with other PCI techniques due to unfavourable clinical outcome in long-term follow-up. However the results of orbital atherectomy presented in the ORBIT I and ORBIT II trials were encouraging. In addition to these encouraging data, necessity for sufficient lesion preparation before implantation of bioresorbable scaffolds lead to resurgence in the use of atherectomy. This article summarises currently available publications on orbital atherectomy (Cardiovascular Systems Inc.) and compares them with rotational atherectomy.

Previous observational studies and meta-analyses reported that the optimal strategy of coronary revascularization (percutaneous coronary intervention [PCI] and bypass surgery) for anatomically complex coronary artery lesions in the chronic hemodialysis setting is still controversial because the long-term outcomes were superior with coronary artery bypass grafting, especially with regard to repeat revascularization; however, short-term mortality with PCI was significantly lower because it is less invasive. Moreover, no guidelines show a strategy for this setting. We report the case of a patient with chronic dialysis and calcified left main true bifurcation lesion who underwent staged PCI with rotational atherectomy and minimally invasive direct coronary artery bypass for in-stent restenosis who died of non-occlusive mesenteric ischemia.

AbstractRotational atherectomy (RA) has been widely used for percutaneous coronary intervention (PCI) to severely calcified lesions. As compared to other countries, RA in Japan has uniquely developed with the aid of greater usage of intravascular imaging devices such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT). IVUS has been used to understand the guidewire bias and to decide appropriate burr sizes during RA, whereas OCT can also provide the thickness of calcification. Owing to such abundant experiences, Japanese RA operators modified RA techniques and reported unique evidences regarding RA. The Task Force on Rotational Atherectomy of the J apanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document to summarize the contemporary techniques and evidences regarding RA.
