AIMS: Percutaneous coronary intervention (PCI) of severe coronary artery calcification (CAC) is challenging. The ORBIT II study demonstrated the safety and efficacy of orbital atherectomy (OA) in patients with severe CAC. Microparticulate liberated during OA may disturb coronary microcirculation. We evaluated OA treatment in patients with left ventricular systolic dysfunction. METHODS AND RESULTS: Patients were grouped by left ventricular ejection fraction (LVEF): 26-40% (n=33), 41-50% (n=90), and >50% (n=314)...

Severe coronary artery calcifications pose an ongoing challenge when performing percutaneous coronary interventions, resulting in an increased likelihood of procedural complications. Orbital atherectomy (OA) has emerged as a promising technology that helps improve outcomes in this complex patient population. Its safety and efficacy are yet to be demonstrated in the setting of acute myocardial infarction. We present a case of a patient with acute ST-elevation myocardial infarction (STEMI) evaluated with emergent transradial coronary angiography...

BACKGROUND/PURPOSE: The presence of heavy coronary artery calcification increases the complexity of percutaneous coronary intervention (PCI) and increases the incidence of major adverse cardiac events (MACE): death, myocardial infarction (MI), target vessel revascularization (TVR), and stent thrombosis. The ORBIT II (Evaluate the Safety and Efficacy of OAS in Treating Severely Calcified Coronary Lesions) trial reported low rates of procedural, 30-day, 1-year, and 2-year ischemic complications after treatment of de novo, severely calcified lesions with the Diamondback 360° Coronary Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc...

OBJECTIVE: We analyzed the incidence of bradycardia and the safety of patients with severely calcified coronary lesions who underwent orbital atherectomy without the insertion of a temporary pacemaker. BACKGROUND: The presence of severely calcified coronary lesions can increase the complexity of percutaneous coronary intervention due to the difficulty in advancing and optimally expanding the stent. High-pressure inflations to predilate calcified lesions may cause angiographic complications like perforation and dissection...

OBJECTIVES: We evaluated the clinical outcomes of elderly patients who underwent orbital atherectomy for the treatment of severe coronary artery calcification (CAC) prior to stenting. BACKGROUND: Percutaneous coronary intervention (PCI) of severe CAC is associated with worse clinical outcomes including death, myocardial infarction (MI), and target vessel revascularization (TVR). The elderly represents a high-risk group of patients, often have more comorbid conditions, and have worse outcomes after PCI compared to younger patients...

OBJECTIVES: We evaluated the clinical outcomes of patients with chronic kidney disease (CKD) who underwent orbital atherectomy for severe coronary artery calcification (CAC) prior to stent implantation. BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with severe CAC is associated with increased rates of adverse clinical events. Patients with CKD are at increased risk for atherosclerotic cardiovascular disease, including vascular calcification, and have worse outcomes after PCI...

Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery...

BACKGROUND: The presence of coronary artery calcification is associated with a significant burden of coronary artery disease along with being a predictor of increased adverse ischemic events. The Diamondback 360® Coronary Orbital Atherectomy System (OAS) is a novel device designed to facilitate treatment of calcified lesions. This study aimed to evaluate the cost-effectiveness of OAS compared to standard treatment. METHODS: A decision tree model utilizing ORBIT II clinical trial and Medicare data from the health system perspective was constructed...

We present a case of a 67-year-old man with stage III chronic kidney disease, uncontrolled diabetes mellitus, coronary artery disease, and high surgical risk who presented with two episodes of acute coronary syndrome attributed to in-stent restenosis (ISR) associated with heavily calcified lesions. In this case, we were able to improve luminal patency with orbital atherectomy system (OAS); however, withdrawal of the device resulted in a device/stent interaction, causing failure of the device. Given limitations in current evidence and therapies, managing ISR can be a technical and cognitive challenge...

BACKGROUND/PURPOSE: Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. METHODS/MATERIALS: A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed...

OBJECTIVES: We evaluated the relationship between gender and angiographic and clinical outcomes in patients with severely calcified lesions who underwent orbital atherectomy. BACKGROUND: Female gender is associated with increased risk of adverse clinical events after percutaneous coronary intervention (PCI). Severe coronary artery calcification increases the complexity of PCI and increases the risk of adverse cardiac events. Orbital atherectomy is effective in plaque modification, which facilitates stent delivery and expansion...

REVIEW
Paul N Fiorilli, Saif Anwaruddin
Despite significant advances in treatment of coronary artery disease and improvements in interventional devices and techniques, the subset of obstructive calcified coronary artery disease remains challenging to treat. Percutaneous treatment of these lesions results in increased rates of procedural complications, as well as a higher risk of stent underexpansion and malapposition. This is associated with higher rates of restenosis, target lesion revascularization (TLR), and major adverse cardiac events (MACE)...

AIMS: Recently, favourable procedural 30-day and one-year outcomes with the Diamondback 360 Orbital Atherectomy System (OAS) in the treatment of severely calcified lesions have been reported. The purpose of this study was to assess the therapeutic mechanism and efficacy of the OAS with optical coherence tomography (OCT) imaging. METHODS AND RESULTS: This was an observational imaging study in 18 patients with complex calcified coro-nary artery lesions who underwent percutaneous coronary intervention with the OAS...

OBJECTIVES: To investigate the safety and efficacy of the coronary Orbital Atherectomy System (OAS) to prepare severely calcified lesions for stent deployment in patients grouped by renal function. BACKGROUND: Percutaneous coronary intervention (PCI) of severely calcified lesions is associated with increased rates of major adverse cardiac events (MACE), including death, myocardial infarction (MI), and target vessel revascularization (TVR) compared with PCI of non-calcified vessels...
