Peripheral arterial disease (PAD), caused by atherosclerotic processes, is allied with an increased risk of ischemic events, limb loss, and death. Recently, the use of a solid-state laser at 355 nm within a hybrid catheter was suggested for that purpose. In this work, short nanosecond pulses of a solid-state laser at 355 nm delivered through a hybrid catheter, composed of optical fibers and a blunt mechanical blade, are used to conduct a pre-clinical study and two clinical cases. The pre-clinical study consisted of an atherosclerotic calcified cadaveric leg and a porcine in vivo trial within the iliac artery, respectively...

In this substudy of the ADAPT-DES trial Généreux et al. compared two years outcomes according to the presence or absence of coronary artery calcification (CAC) as assessed by coronary angiography. Coronary calcification was an independent predictor of interventional treatment failure and a higher incidence of both ischemic events and bleeding. The cohort with CAC was older with a higher prevalence of risk factors and comorbidities and an increased anatomical complexity of the target lesions, explaining only in part the worse outcome of the CAC population that persisted at multivariate analysis...

PURPOSE: Directional atherectomy (DA) was introduced for the management of infrainguinal arterial stenosis or occlusive lesions. The procedure success rate in the DEFINITIVE LE study was determined using radiologic imaging. The aim of our study was to determine the usefulness of intraoperative ultrasonography (USG) during DA for evaluating the early results of this procedure. METHODS: Patients who underwent DA from January to December 2014 were reviewed retrospectively...

BACKGROUND: The impact of endovascular revascularization of the lower extremity arteries with atherectomy (AT) compared with percutaneous transluminal angioplasty (PTA) is still unclear. Therefore, the aim of the study was to compare long-term outcomes after percutaneous PTA and AT in patients requiring endovascular revascularization.Methods and Results:This was a single-center, retrospective registry of obstructive and symptomatic PAD patients who underwent endovascular revascularization...

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...

We present two cases with chronic total occlusion of the saphenous vein graft in two patients with a history of previous bypass surgery with unfavorable anatomic features for recanalization of the native coronary artery. In the first case, two dedicated attempts for recanalization of chronic total occlusion of the native artery failed and in the second case there was not an adequate visualization of the native vessel beyond the occlusion point, not even by contralateral injection. Excimer laser atherectomy was used in both cases as an adjuvant therapy during recanalization of the saphenous vein graft in combination with a distal protection device in order to reduce distal embolization...

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...

OBJECTIVES: To study the long-term outcomes of rotational atherectomy (RA) for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: There is little evidence on the incidence, procedural results and long-term outcomes of RA for CTO PCI. METHODS: This registry included data from consecutive patients undergoing CTO PCI at four specialized centers. Major adverse cardiac events (MACE: cardiac death, target-vessel myocardial infarction and ischemia-driven target-vessel revascularization) on follow-up were the primary endpoint...

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...

PURPOSE: To report a single-center study comparing drug-coated balloon (DCB) angioplasty vs directional atherectomy with antirestenotic therapy (DAART) for isolated lesions of the popliteal artery. METHODS: Seventy-two patients were treated with either DCB angioplasty alone (n=31) or with DAART (n=41) for isolated popliteal artery stenotic disease between October 2009 and December 2015. The majority of patients presented with lifestyle-limiting claudication (74% vs 86%, respectively)...

AIMS: The safety and efficacy of rotational atherectomy (RA) in patients presenting with non-ST-elevation myocardial infarction (NSTE-ACS) remain to be defined. The aim of our study was to assess the safety and efficacy of RA in NSTE-ACS patients with reference to both short- and long-term follow-up. METHODS AND RESULTS: This was an observational retrospective registry which enrolled all consecutive patients undergoing RA, comparing patients with stable angina (SA) and NSTE-ACS...

AIMS: The aim of this multicentre study was to investigate the in-hospital and midterm outcomes of rotational atherectomy (RA) followed by metallic stent implantation. METHODS AND RESULTS: Between 2002 and 2013, 1,176 de novo lesions with calcified coronary lesions treated by RA and metallic stent implantation at nine institutions were assessed. Patients with ST-segment elevation myocardial infarction (STEMI) within 30 days, cardiogenic shock before the procedure, lesions with thrombus, and in-stent restenosis were excluded from the current analysis...

OBJECTIVES: The aim of this study was to compare outcomes of bailout and planned rotational atherectomy (RA) in the treatment of calcified coronary lesions. BACKGROUND: Current guidelines recommend RA as a bailout procedure for calcified or fibrotic lesions that cannot be adequately dilated before stenting. Nonetheless, planned RA is sometimes performed in certain challenging anatomies. METHODS: Data of patients treated with RA between 2002 and 2014 at a single-center registry were retrospectively analyzed...

OBJECTIVE: The purpose of this study was to evaluate the trends in procedure volume, clinical sites of care, and Medicare expenditure for peripheral vascular interventions (PVIs) for lower extremity occlusive disease since the Centers for Medicare and Medicaid Services instituted reimbursement policy changes that broadened payment for procedures performed in physician-owned office-based laboratories (OBLs). METHODS: We analyzed fee-for-service Medicare claims data from 2011 to 2014 to obtain the frequency of use of PVI by type, care setting, and physician specialty...

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: The usage of rotational atherectomy (RA) is growing in the current percutaneous coronary intervention (PCI) because of the expansion of PCI indication to more complex lesions. However, the complications after RA have been linked to procedure-related morbidity and mortality. The purpose of this study was to investigate the incidence and determinants of complications in RA using a large nationwide registration system in Japan (J-PCI). METHODS AND RESULTS: The primary composite outcome of this study was defined as the occurrence of in-hospital death, cardiac tamponade, and emergent surgery after RA...
