Background: Rotational atherectomy (RA) is used to improve procedural success of percutaneous catheter interventions (PCIs) of complex and heavily calcified coronary lesions. We report the clinical experience and outcomes in our institution with the use of RA, followed by drug-eluting stent implantation. Materials and Methods: Data of 81 patients treated with PCI and adjunctive RA were analyzed. Clinical follow-up for the occurrence of major adverse events (MAEs) was obtained in all patients and correlated with significant variables using multivariate Cox proportional hazards analysis...

We aimed to evaluate the optical frequency-domain imaging (OFDI) findings after rotational atherectomy (RA) that predict good stent expansion for severely calcified coronary lesions. Fifty consecutive calcified lesions were subjected to RA under OFDI guidance. We performed OFDI just after RA and stenting. We measured the morphology of calcium after RA, and assessed how these factors influence stent expansion. The stent expansion index was defined as the minimum stent area divided by the average of the proximal and distal reference lumen areas...

OBJECTIVES: To evaluate the short- and long-term clinical outcomes of RA in CTO coronary intervention. BACKGROUND: The application of rotational atherectomy (RA) may improve the success rate of percutaneous recanalization of chronic total occlusion (CTO) with heavy calcification. METHODS: From January 2011 to September 2014, we enrolled 285 patients with CTO who underwent successful percutaneous coronary intervention (PCI). Resistant CTO lesions were defined as those with heavy calcifications as well as those that no devices are able to pass after guide wire crossing...

BACKGROUND: Rotational atherectomy (RA) is an acknowledged method of percutaneous treatment of highly calcified or fibrotic coronary lesions. However, using the rotablator system in patients presenting with acute coronary syndromes (ACS) remains controversial and is considered as a relative contraindication. The aim of our study was to assess in-hospital and 1-year outcomes in patients undergoing RA presenting with ACS, in comparison to elective RA procedures. METHODS: This single-center observational study included all consecutive patients who underwent RA and PCI in our institution from April 2008 to October 2015...

INTRODUCTION: New-generation drug-eluting stents (NG-DES) are superior to early generation DES (EG-DES) in the majority of lesion and patient subsets, but comparative data in patients with severely calcified coronary lesions are lacking. This study aims to compare clinical outcomes of EG-DES and NG-DES in patients undergoing rotational atherectomy (RA) in calcified lesions. METHODS: Data of 268 patients (288 lesions) treated with EG-DES and 213 patients (225 lesions) receiving NG-DES after RA were retrospectively analyzed from a single-center registry...

Percutaneous coronary intervention for the treatment of a severe calcified lesion is still one of the most technically challenging areas of interventional cardiology. Calcified lesions are a cause of stent underexpansion, which significantly increases the subsequent risks of in-stent restenosis and thrombosis, even when drug-eluting stents are used. In this report, we describe the usefulness of prolonged inflations using a scoring balloon catheter (Scoreflex) for severe calcified lesions. Prolonged inflation using a scoring balloon enables an adequate dilation for treatment of a severe calcified plaque that was unresponsive to conventional technique with or without rotational atherectomy...

Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

Intravascular ultrasound (IVUS) is mainly used in PCI to treat complex lesions, such as left main bifurcation, chronic total occlusion and calcified lesions. Although IVUS yields useful information such as the presence of napkin-ring calcification, the role of IVUS in rotational atherectomy (RA) is not fully appreciated. Recently, since the deliverability and crossability of IVUS catheters have improved, IVUS should be attempted before RA. Even if the IVUS catheter cannot cross the lesion, IVUS provides information just proximal to the target lesion, which would be useful in the selection of the appropriate guidewire and burr size...

Longitudinal rotational atherectomy of metal struts is well described as bail-out strategy to treat undilatable instent restenosis. Ablation of metal stent struts jailing the ostium of a major side branch in a coronary bifurcation is not described. In the current report, we describe a case of "transverse" rotational atherectomy to treat a failure of culotte stenting in a left main stem bifurcation. We document for the first time in vivo and in man the effect of this strategy using optical coherence tomography...

The impact of lesion complexity on long-term vascular response to cobalt-chromium everolimus-eluting stent (CoCrEES) remains unclear. We sought to evaluate them using optical coherence tomography (OCT). A total of 47 patients with 58 lesions treated only with CoCrEES and no target-vessel events within 5 years after implantation were prospectively enrolled and underwent 5-year follow-up OCT. Quantitative parameters and qualitative characteristics of the neointima were evaluated using multilevel logistic or linear regression models with random effects at three levels: lesion, cross-section (CS), and strut...

Severe coronary artery calcification (CAC) increases the complexity of percutaneous coronary intervention (PCI) by inhibiting optimal stent expansion, leading to an increased risk of death, myocardial infarction, repeat revascularization, and stent thrombosis. Coronary atherectomy modifies and debulks calcified plaque to facilitate PCI. Although there is no clear consensus, and further studies are needed, the decision to perform atherectomy should be based upon the presence of fluoroscopic CAC or with the use of intravascular imaging...

INTRODUCTION: The efficacy of heparin based flush solutions in rotational atherectomy (RA) has not been validated. Recently, a single center study demonstrated the feasibility of an alternative flush solution with 10,000U of unfractionated heparin (UFH) in 1L of normal saline. We aimed to evaluate the safety and efficacy of an alternative flush solution intermittently utilized at our institution. METHODS: We retrospectively identified 150 patients undergoing RA over a three year period...

An 83-year-old man presented with recurrent acute coronary syndrome (ACS) at the left main coronary artery (LMCA) complicated with ostial chronic total occlusion (CTO) in the right coronary artery (RCA) (RCA-CTO). At the first LMCA-ACS approximately 1 year earlier, he had undergone LMCA-crossover stenting with a biolimus-eluting stent in the presence of RCA-CTO. At the second LMCA-ACS, we angiographically confirmed severe in-stent restenosis in the distal LMCA, in addition to angled severe stenosis in the just proximal LCx, and performed primary PCI for the LMCA bifurcation lesion under intra-aortic balloon pumping support...
