Abstract
Objective: This study aims to elucidate the differences in vessel patency rates, procedural complications, and the need for repeat interventions between these two techniques, thereby providing insights into the optimal atherectomy strategy for managing peripheral arterial disease in the femoropopliteal segment. Material and Methods: This retrospective study investigated the long-term effectiveness of two atherectomy techniques, rotational atherectomy (RA) and directional atherectomy (DA), in treating lower extremity peripheral artery disease (LE-PAD) affecting the superficial femoral artery (SFA) and popliteal arteries. A total of 134 patients with symptomatic LE-PAD and significant stenosis (70%-99%) were included and divided into two groups based on the atherectomy method used. Both groups underwent similar pre- and post-atherectomy procedures, including drug-coated balloon angioplasty. The primary outcome measure was clinical success, defined as procedural success and an improvement in Rutherford classification at 1 year. Results: Baseline characteristics were similar between the two groups, with no significant differences in demographics or lesion characteristics, except for a higher proportion of right-sided lesions in the DA group. While both RA and DA effectively improved ankle-brachial index (ABI) and Rutherford classification at 12 months, RA demonstrated superior long-term benefits, with significantly higher ABI at 24 months and a greater proportion of asymptomatic patients. Although RA had a longer procedural duration and a higher incidence of dissection, it resulted in lower residual stenosis and fewer cases of treated segment thrombosis than DA. Both RA and DA are effective treatment options for femoropopliteal lesions, but RA may offer advantages in long-term symptom management and vessel patency. Conclusion: Both rotational and directional atherectomy effectively treat femoropopliteal lesions, with rotational atherectomy demonstrating superior long-term outcomes in terms of symptom management and vessel patency. Despite longer procedural times and a slightly higher risk of dissection, rotational atherectomy resulted in lower residual stenosis and fewer cases of treated segment thrombosis than directional atherectomy.

Abstract
Atherosclerosis affects human health in many ways, leading to disability or premature death due to ischemic heart disease, stroke, or limb ischemia. Poststenotic blood flow disruption may also play an essential role in artery wall impairment linked with hemolysis related to shear stress. The maximum shear stress in the atherosclerotic plaque area is the main parameter determining hemolysis risk. In our work, a 3D internal carotid artery model was built from CT scans performed on patients qualified for percutaneous angioplasty due to its symptomatic stenosis. The obtained stenosis geometries were used to conduct a series of computer simulations to identify critical parameters corresponding to the increase in shear stress in the arteries. Stenosis shape parameters responsible for the increase in shear stress were determined. The effect of changes in the carotid artery size, length, and degree of narrowing on the change in maximum shear stress was demonstrated. Then, a correlation for the quick initial diagnosis of atherosclerotic stenoses regarding the risk of hemolysis was developed. The developed relationship for rapid hemolysis risk assessment uses information from typical non-invasive tests for treated patients. Practical guidelines have been developed regarding which stenosis shape parameters pose a risk of hemolysis, which may be adapted in medical practice.

Abstract
Catheter-based atherectomy has been discussed for some years, although the conclusions have been controversial. Recent study data did show the feasibility of multifunctional atherectomy devices for complex lesion morphologies, with moderate material use. This is then thus an alternative to bypass surgery, although a direct comparison is lacking.The results of the ByCross approval study were compared to technical and clinical data from various atherectomy systems in terms of range of indication, limitations as defined by the manufacturer, the success and complication rate and the instructions for use. As in many recent studies, a residual stenosis ≤ 50% after atherectomy and ≤ 30% in the completion imaging was defined as the primary endpoint and proof of technical success.Lesions recruited for the ByCross study were more complex than in other studies, with respect to the lesion length (124.7 mm vs. 34 mm in the EASE study and 67.2 mm in the VISION study) and the degree of stenosis (99.4% vs. 88.5% in the EASE and 78,7% in the VISION study). Calcification was also more severe - as defined by the PACSS (Peripheral Artery Calcification Severity Score). ByCross allowed recanalisation of lesions without wire passage prior to atherectomy (26.82%), which is a must for all other systems. The variable tip diameter of the ByCross can achieve a lumen gain of 4.7 mm without tip or wire exchange or run time limits. The 0% rate of embolic events, which is unique for atherectomy device approval studies, can be explained by the working principle and the high aspiration rate. No vessel injuries occurred, and the 6-month follow-up results showed 0% revascularisation rate.New generation atherectomy systems offer safe and effective enlargement of the endovascular portfolio. The ByCross device is an atherectomy, thrombectomy and crossing device free from investment and has a wider range of indications for the iliac and the femorodistal segments, which supports ByCross atherectomy as an alternative for bypass surgery.

Abstract
Peripheral arterial disease is an increasingly prevalent condition with significant associated morbidity, mortality, and health care expenditure. Endovascular interventions are appropriate for most patients with either ongoing symptoms of intermittent claudication despite lifestyle and medical optimization or chronic limb-threatening ischemia. The femoropopliteal segment is the most common arterial culprit responsible for claudication and the most commonly revascularized segment. Endovascular approaches to revascularization of the femoropopliteal segment are advancing with an evolving landscape of techniques for arterial access, device-based therapies, vessel preparation, and intraprocedural imaging. These advances have been marked by debate and controversy, notably related to the safety of paclitaxel-based devices and necessity of atherectomy. In this review, we provide a critical overview of the current evidence, practice patterns, emerging evidence, and technological advances for endovascular intervention of the femoropopliteal arterial segment.

Abstract
Atherectomy is an effective vessel prepping device but not all atherectomy devices are equal. The depth of vessel injury and residual narrowing vary considerably among atherectomy devices with significant implications on outcome. Precision imaging is critical to optimize outcome using atherectomy as a vessel prepping technique. Prospective trials need to test the hypothesis that precision imaging has a significant impact on how operators approach the treatment of infrainguinal arterial disease.

Abstract
Peripheral arterial disease is estimated to affect more than 200 million people worldwide. Although more than 50% of those affected are asymptomatic, it accounts for 3-4% of amputations and a crude five-year death rate of 82.4 deaths per 1000 patient-years when adjusted for duration of follow-up. Additionally, peripheral artery disease is often an indicator of obstructive atherosclerotic disease involvement of cerebral and coronary vessels, consequently increasing the risk of stroke, cardiovascular death, and myocardial infarction in these patient populations. The management of peripheral arterial disease includes conservative therapies, pharmacological treatments, interventional and surgical revascularization of blood vessels. Percutaneous transluminal angioplasty with balloons and stents has improved clinical outcomes compared to medical treatment alone. Despite these advances, the prevalence of peripheral arterial disease remains high. This review article aims to provide focused, up-to-date information on the clinical course, diagnosis, medical and interventional approach of the management of peripheral artery disease.

Abstract
BACKGROUND Optical coherence tomography (OCT) is a novel adjunct in the field of medicine. The objective of this systematic review was to evaluate the role of OCT in the field of contemporary endovascular surgery in terms of its utility in diagnostics and interventions in peripheral arterial disease (PAD). METHOD A systematic search of literature published from 1st January 2009 to 1st August 2019 was identified from PubMed, Ovid and Cochrane library database with reference to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The pre-defined selection inclusion criteria were clinical applications of OCT in vascular surgery in relation to diagnostics and interventions. Keywords used included OCT, PAD, endovascular procedures and atherectomy. RESULTS From an initial search of 310 articles, 27 articles were included in this systematic review: 15 articles were related to diagnostics: peripheral arterial disease was the most studied condition (n = 8), other conditions included in-stent restenosis (n = 4), fibromuscular dysplasia (n = 2) and acute limb ischaemia (n = 1); 12 articles were related to intervention: an OCT-guided crossing catheter was the most used assisting device (n = 10), with an OCT-guided atherectomy device used in four of these studies. CONCLUSION Although there is currently no level 1 evidence to suggest routine use of OCT in the diagnosis and treatment of PAD, current literature suggests that the use of OCT is safe and effective. The OCT real-time vessel wall structural images clearly distinguish normal anatomy from plaque pathology, and are of great advantage both in the accurate diagnosis and treatment of target lesion, especially in reducing the amount of radiation in the endovascular procedure.

Abstract
BACKGROUND Carbon dioxide angiography with addition of optical coherence tomography imaging may improve procedural success and clinical outcomes in patients with peripheral artery disease and chronic kidney disease. METHODS Single-center, retrospective analysis of patients with chronic kidney disease who underwent carbon dioxide angiography and optical coherence tomography-guided chronic total occlusion crossing and/or optical coherence tomography-guided directional atherectomy was performed. Patient and procedure-related characteristics, along with peri- and one-year post-procedural major adverse events, were analyzed. RESULTS A total of 18 vessels in 11 patients, with mean age 70 years were treated. All had co-morbidities such as hypertension, hyperlipidemia, had history or were current smokers with baseline peripheral artery disease. Majority were diabetic with coronary disease (82%); 55% baseline chronic kidney disease IV, 55% Rutherford class III and 45% class IV. Contrast was used in only two patients. Mean total fluoroscopy time and radiation dose was 24.1 min and 249.2 mGY, respectively. Half of the lesions were femoro-popliteal chronic total occlusions, and Ocelot catheter was used to cross seven of nine chronic total occlusions and was successful in six. Adjunctive optical coherence tomography-guided directional atherectomy was performed in 8 of 11 patients. Only two adverse events occurred: one clinically significant event of slow-flow intra-procedurally and one target limb revascularization within one year of index procedure in a vessel different than prior treated. Optical coherence tomography imaging in both chronic total occlusion-crossing and atherectomy resulted in 10-min mean fluoroscopy reduction time and 32 mGY reduction in radiation dose. CONCLUSION Carbon dioxide angiography with the addition of optical coherence tomography imaging for chronic total occlusion crossing and/or optical coherence tomography-guided directional atherectomy reduced the need for contrast agents, total fluoroscopy time, and radiation exposure in patients with peripheral artery disease and baseline chronic kidney disease.

Abstract
Background Plain balloon angioplasty has traditionally been used to treat lower limb arterial disease but can be limited by significant residual stenosis, vessel recoil, dissection, and by late restenosis. Appropriate vessel preparation may significantly improve short and long-term outcomes. We aim to give an overview of some of the devices currently available, or under investigation, for vessel preparation in the lower limb. Main text Vessel preparation devices include those that remove plaque (atherectomy devices) and those that modify plaque. The four groups of plaque removing atherectomy devices are defined by their plaque removal method: Directional, rotational orbital and excimer laser are categories of devices investigated for plaque modification. Intravascular lithotripsy devices generate sonic pulsatile pressure waves that pass into the vessel wall cracking calcified plaques whilst sparing soft tissue. This enables dilatation of calcified lesions at low pressure by conventional balloons and enables full stent expansion. Other balloon based vessel preparation devices were designed to modify plaque and produce more controlled, lower pressure luminal expansion without major dissections and potentially with less recoil than conventional angioplasty balloons. Scoring balloons have a helical nitinol element attached to the balloon that scores plaque facilitating uniform luminal enlargement. Further specialty balloons have been developed in recent years, including the Chocolate, Phoenix and Serranator balloons. Finally, the temporary Spur self-expanding retrievable nitinol stent has a series of radially aligned spurs that are driven into the vessel wall by post-dilatation, potentially improving drug delivery. Conclusion Lesion specific vessel preparation aims to improve both short and long term outcomes through improved penetration of anti-proliferative drug, maximising luminal gain, reducing the need for stent placement and minimising intimal injury. Some forms of vessel preparation appear to improve short term outcomes; long-term outcomes remain uncertain. An overview of some of the multiple devices available for vessel preparation is presented.

Abstract
Symptomatic peripheral arterial disease management involves medical treatment and interventional procedures. Intermittent claudication and critical limb threatened ischemia (CLTI) should be individually considered with specific outcomes and procedures. When intervention is required, an endovascular approach is usually the first-line option. Plain balloon angioplasty was previously used to dilate clinically significant femoropopliteal lesions with variable results. However, over recent years, the use of self-expanding nitinol stents has enabled treatment of long lesions, yielding significantly improved clinical results. Drug-eluting technology has also exhibited a capacity to limit in-stent restenosis and to drive target revascularization. Nevertheless, calcifications and elastic recoil of the arterial wall remain risk factors for early restenosis and failure. Therefore, vessel preparation using specific devices is required to modify vessel compliance and debulk obstructive calcification. In this short review, we provide an overview of the options for gaining lumen before stenting or dilation using drug-coated balloons.

Abstract
The treatment of isolated calcified lesions involving the popliteal artery are demanding and they often require stent placement to achieve acceptable luminal gain. This study evaluates the safety and performance of the orbital atherectomy system (Cardiovascular Systems Inc.) and percutaneous transluminal angioplasty with a drug-coated balloon (PTA-DCB) for the treatment of chronic atherosclerotic lesions within the popliteal artery segment. From November 2018 to November 2019, a series of six patients with Rutherford classification stage III peripheral arterial disease with isolated, focal, calcified occlusions of the popliteal artery were treated with orbital atherectomy followed by PTA-DCB. No embolic protection devices were used. The technical success rate was 100%, the primary patency rate was 100% at 7.0 (±4.2) months of follow-up. The Rutherford classification improved in all patients from stage III to stage II and the mean ankle brachial pressure index after the procedure was 0.97 (±0.08), with a preoperative mean ankle brachial pressure index of 0.69 (±0.21). In one instance, spasm was noted in a distal arterial bed and it was successfully treated with local nitroglycerine. No distal embolisation, perforation or aneurysmal degeneration was observed. During follow-up there were no deaths, major amputations or revascularisation of target lesions. The use of orbital atherectomy system in combination with PTA-DCB was found to be safe and effective in modifying focal, chronic, calcified plaques in the popliteal artery segment in these six cases.

Abstract
Objectives The aim was to report the mid-term outcomes of Jetstream™ rotational atherectomy device in complex femoropopliteal lesions. Methods Between November 2016 and April 2018, 55 patients who were treated with rotational atherectomy and adjunctive balloon angioplasty due to complex femoropopliteal lesions were retrospectively scanned. Results Fifty-five patients who underwent endovascular treatment with rotational atherectomy for chronic total occlusive femoropopliteal lesions were included in the study. Technical success rate was 100%. The mean age was 63 (±10.5) years. The cohort included 25 (45.4%) diabetics and 45 (81.8%) current smokers. The mean length of the lesions was 20.8 ± 11.2 cm. Chronic total occlusive lesions were detected in 35 (63.6%) patients, and mixed-type steno-occlusive lesions were detected in 20 patients (36.4%). Thirty-three (60%) lesions were moderate or severely calcified. Adjunctive balloon angioplasty was performed with plain old balloon angioplasty (POBA) on 31 (56.4%) patients and with drug-coated balloon angioplasty on 24 (43.6%) patients. After adjunctive balloon angioplasty, flow limiting dissection was observed in 20 (36.3%) patients, and 17 (30.9%) patients needed stent implantation. The Kaplan–Meier analysis method estimated that the overall primary patency rates at 12 and 24 months were 81.8% and 70.9%, respectively. Overall, secondary patency rates at 12 and 24 months were 94.5% and 80%. No statistically significant differences of 24-month primary patency and secondary patency rates were found between patients treated with drug-coated balloon angioplasty and POBA as an adjunctive therapy, even though primary patency (83.3% vs. 61.3%, p = .06) and secondary patency (91.7% vs. 71%, p = .56) rates of drug-coated balloon angioplasty were slightly higher than POBA. Patients with claudication had better primary patency (90.5% vs. 58.8%, p = .001) and secondary patency (100% vs. 67.6%, p = .004) rates than patients with critical limb ischemia at 24 months. Significant differences between patients who did and did not stop smoking were found in 24-month primary patency (57% vs. 88%, p = .007) and secondary patency (67% vs. 96%, p = .007). Six patients underwent unplanned amputation. There were eight (14.5%) mortalities during follow-up. Conclusions Rotational atherectomy with adjunctive balloon angioplasty has satisfactory technical success rates and mid-term outcomes. As an adjunctive method, there was no difference between drug-coated balloon angioplasty s and POBAs. Smoking cessation is always the first-step treatment to improve mid-term patency results. Patients with critical limb ischemia have worse patency results compared to the patients with claudication.

Abstract
BACKGROUND Symptomatic peripheral arterial disease (PAD) has several treatment options, including angioplasty, stenting, exercise therapy, and bypass surgery. Atherectomy is an alternative procedure, in which atheroma is cut or ground away within the artery. This is the first update of a Cochrane Review published in 2014. OBJECTIVES To evaluate the effectiveness of atherectomy for peripheral arterial disease compared to other established treatments. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Allied and Complementary Medicine (AMED) databases, and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 12 August 2019. SELECTION CRITERIA We included all randomised controlled trials that compared atherectomy with other established treatments. All participants had symptomatic PAD with either claudication or critical limb ischaemia and evidence of lower limb arterial disease. DATA COLLECTION AND ANALYSIS Two review authors screened studies for inclusion, extracted data, assessed risk of bias and used GRADE criteria to assess the certainty of the evidence. We resolved any disagreements through discussion. Outcomes of interest were: primary patency (at six and 12 months), all-cause mortality, fatal and non-fatal cardiovascular events, initial technical failure rates, target vessel revascularisation rates (TVR; at six and 12 months); and complications. MAIN RESULTS We included seven studies, with a total of 527 participants and 581 treated lesions. We found two comparisons: atherectomy versus balloon angioplasty (BA) and atherectomy versus BA with primary stenting. No studies compared atherectomy with bypass surgery. Overall, the evidence from this review was of very low certainty, due to a high risk of bias, imprecision and inconsistency. Six studies (372 participants, 427 treated lesions) compared atherectomy versus BA. We found no clear difference between atherectomy and BA for the primary outcomes: six-month primary patency rates (risk ratio (RR) 1.06, 95% confidence interval (CI) 0.94 to 1.20; 3 studies, 186 participants; very low-certainty evidence); 12-month primary patency rates (RR 1.20, 95% CI 0.78 to 1.84; 2 studies, 149 participants; very low-certainty evidence) or mortality rates (RR 0.50, 95% CI 0.10 to 2.66, 3 studies, 210 participants, very low-certainty evidence). One study reported cardiac failure and acute coronary syndrome as causes of death at 24 months but it was unclear which arm the participants belonged to, and one study reported no cardiovascular events. There was no clear difference when examining: initial technical failure rates (RR 0.48, 95% CI 0.22 to 1.08; 6 studies, 425 treated vessels; very low-certainty evidence), six-month TVR (RR 0.51, 95% CI 0.06 to 4.42; 2 studies, 136 treated vessels; very low-certainty evidence) or 12-month TVR (RR 0.59, 95% CI 0.25 to 1.42; 3 studies, 176 treated vessels; very low-certainty evidence). All six studies reported complication rates (RR 0.69, 95% CI 0.28 to 1.68; 6 studies, 387 participants; very low-certainty evidence) and embolisation events (RR 2.51, 95% CI 0.64 to 9.80; 6 studies, 387 participants; very low-certainty evidence). Atherectomy may be less likely to cause dissection (RR 0.28, 95% CI 0.14 to 0.54; 4 studies, 290 participants; very low-certainty evidence) and may be associated with a reduction in bailout stenting (RR 0.26, 95% CI 0.09 to 0.74; 4 studies, 315 treated vessels; very low-certainty evidence). Four studies reported amputation rates, with only one amputation event recorded in a BA participant. We used subgroup analysis to compare the effect of plain balloons/stents and drug-eluting balloons/stents, but did not detect any differences between the subgroups. One study (155 participants, 155 treated lesions) compared atherectomy versus BA and primary stenting, so comparison was extremely limited and subject to imprecision. This study did not report primary patency. The study reported one death (RR 0.38, 95% CI 0.04 to 3.23; 155 participants; very low-certainty evidence) and three complication events (RR 7.04, 95% CI 0.80 to 62.23; 155 participants; very low-certainty evidence) in a very small data set, making conclusions unreliable. We found no clear difference between the treatment arms in cardiovascular events (RR 0.38, 95% CI 0.04 to 3.23; 155 participants; very low-certainty evidence). This study found no initial technical failure events, and TVR rates at six and 24 months showed little difference between treatment arms (RR 2.27, 95% CI 0.95 to 5.46; 155 participants; very low-certainty evidence and RR 2.05, 95% CI 0.96 to 4.37; 155 participants; very low-certainty evidence, respectively). AUTHORS' CONCLUSIONS This review update shows that the evidence is very uncertain about the effect of atherectomy on patency, mortality and cardiovascular event rates compared to plain balloon angioplasty, with or without stenting. We detected no clear differences in initial technical failure rates or TVR, but there may be reduced dissection and bailout stenting after atherectomy although this is uncertain. Included studies were small, heterogenous and at high risk of bias. Larger studies powered to detect clinically meaningful, patient-centred outcomes are required.

Abstract
Lumivascular optical coherence tomography (OCT) is a novel adjunct in the field of medicine. It offers clear real-time imaging of artery walls before and during endovascular intervention. This study reports our initial experience on the use of lumivascular OCT-guided atherectomy in the management of two patients with recurrent restenosis in their femoropopliteal arteries associated with in-stent restenosis. Endovascular procedures were successful with a Pantheris atherectomy device (Avinger, Redwood City, CA, USA) and drug-eluting balloons. The OCT images clearly distinguished normal anatomy from plaque pathology, were of great advantage in both the accurate diagnosis and treatment of target lesions, and may reduce radiation during the endovascular procedure. However, the price of the device and its need for contrast infusion limit its routine clinical use.

Abstract
INTRODUCTION The rate of atherectomy utilization in peripheral artery diseases (PAD) is growing. The two atherectomy devices available on the market and used most frequently are the directional and rotational ones. Nonetheless, there is a lack of direct comparison between these two types of atherectomy in PAD. AIM To compare the long-term outcomes after PAD endovascular revascularization with two types of atherectomies: rotational (AR) (Phoenix Philips) and directional (AD) (SilverHawk Medtronic). MATERIAL AND METHODS This was a single-center, retrospective study of obstructive and symptomatic PAD patients who underwent revascularization with atherectomy. The endpoints were considered as target lesion revascularization (TLR), death, amputations and bailout stenting (BS). RESULTS The AR group consisted of 97 patients, while the AD group consisted of 85 individuals. There were no significant differences between the groups in terms of baseline characteristics except for an increased critical limb ischemia (CLI) prevalence in the AR group. The mean follow-up for AD and AR was 282.6 ±147.4 and 255.7 ±186.1 days, respectively (p = 0.44). There were no significant differences in the death rate (AD: 1 (1.7%) vs. AR: 5 (5.7%); p = 0.54), amputations (AD: 2 (2.3%) vs. AR: 5 (5.7%); p = 0.45) or bailout stenting (AD: 2 (2.3%) vs. AR: 3 (3.2%); p = 0.74), whereas TLR was more frequent in the AD group (AD: 25 (29%) vs. AR: 15 (15.9%; p = 0.03). The Kaplan-Meier analysis showed no significant differences between the groups in time to TLR, amputation or death. CONCLUSIONS In this hypothesis-generating study the AR had a lower rate of TLR when compared to the AD. Nevertheless, this should be confirmed in further controlled randomized trials.

Abstract
Background Intravascular imaging plays an important part in diagnosis of vascular conditions and providing insight for treatment strategy. Two main imaging modalities are intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The objective of this study was to prove non-inferiority of OCT imaging to IVUS images in matched segments of peripheral vessels in patients with suspected peripheral vascular disease. Methods The SCAN study was a prospective, non-inferiority clinical study of matched IVUS and OCT images collected along defined segments of peripheral vessels from twelve subjects (mean age 68 ± 10.3 years; 10 men) displaying symptoms of vascular disease. Luminal diameters were measured by both imaging systems at the distal, middle, and proximal points of the defined segments. Three blinded interventional radiologists evaluated the quality of both imaging modalities in identifying layered structures (3-point grading), plaque (5-point grading), calcification (5-point grading), stent structure (3-point grading), and artifacts (3-point grading) from 240 randomly ordered images. Mean grading scores and luminal diameters were calculated and analyzed with Student’s t-Test and Mann-Whitney-Wilcoxon testing. Intrareader reproducibility was calculated by intraclass correlation (ICC) analysis. Results The mean scoring of plaque, calcification, and vascular stent struts by the three readers was significant better in terms of image quality for OCT than IVUS (p < 0.001, p = 0.001, p = 0.004, respectively). The mean scores of vessel wall component visibility and artifacts generated by the two imaging systems were not significantly different (p = 0.19, p = 0.07, respectively). Mean vessel luminal diameter and area at three specific locations within the vessels were not significantly different between the two imaging modalities. No patient injury, adverse effect or device malfunction were noted during the study. Conclusions Imaging by OCT provides the physician with better visualization of some vessel and plaque chacteristics, but both IVUS and OCT imaging are safe and effective methods of examining peripheral vessels in order to perform diagnostic assessment of peripheral vessels and provide information necessary for the treatment strategy of peripheral artery disease. Trial registration NCT03480685 registered on 29 March 2018.

Abstract
Introduction The population of patients with lower limb atherosclerosis includes a considerable proportion of individuals with long superficial femoral artery (SFA) lesions. Chronic total occlusions (CTOs) represent the "last frontier" of percutaneous interventions. While open strategies are considered earlier as standard management for these lesions, the results of a number of trials indicate that endovascular management might become an effective alternative to surgery. Material and methods This paper presents 5-year outcomes of a first-in-man (FIM) study (before CE mark) and the registry of OCT Guided Ocelot Catheter (Avinger) for chronic total occlusions of the superficial femoral artery. The study group comprised 10 patients with Rutherford 3 lower limb ischemia including nine men and one woman. Results The efficacy of the primary intervention was 90%. Angiography performed at 6 months of the procedure, according to the study protocol, revealed 3 and 1 cases of restenosis and reocclusion, respectively, repaired using PTA and open common and deep femoral artery patch plasty. Doppler ultrasound performed at 1, 2 and 5 years after the primary intervention did not reveal significant target vessel restenosis. The primary and primary-assisted patency was 89%. During a 5-year follow-up, four peripheral percutaneous interventions and one femoropopliteal bypass surgery were performed in non-target limbs. There were no cardiovascular deaths, myocardial infarction or stroke and no amputation was required. Conclusions This is a first-in-man study reporting long-term follow-up after SFA CTO revascularization using the Ocelot catheter. The catheter proved to have a satisfactory safety profile and a high proportion of CTO crossings. A 5-year follow-up revealed high primary and primary-assisted patency rates.

Abstract
Atherosclerosis is a chronic immunomodulated disease that affects multiple vascular beds and results in a significant worldwide disease burden. Conventional imaging modalities focus on the morphological features of atherosclerotic disease such as the degree of stenosis caused by a lesion. Modern CT, MR and positron emission tomography scanners have seen significant improvements in the rapidity of image acquisition and spatial resolution. This has increased the scope for the clinical application of these modalities. Multimodality imaging can improve cardiovascular risk prediction by informing on the constituency and metabolic processes within the vessel wall. Specific disease processes can be targeted using novel biological tracers and "smart" contrast agents. These approaches have the potential to inform clinicians of the metabolic state of atherosclerotic plaque. This review will provide an overview of current imaging techniques for the imaging of atherosclerosis and how various modalities can provide information that enhances the depiction of basic morphology.

Abstract
The standard of care for treating symptomatic peripheral arterial disease has been percutaneous transluminal angioplasty with or without stenting over the last couple of years. This endovascular treatment of claudicants or patients with critical limb ischemia has increased in numbers and has even surpassed open surgery. Our daily practice has evolved to an endovascular-first approach, especially in the femoropopliteal region, being the most frequently treated vessel. However, neointimal hyperplasia and elastic recoil leading to target lesion restenosis or occlusion after initial successful treatment is not uncommon. In recent years, drug-eluting technologies on balloons or stents have been investigated as a potential solution for this problem with excellent results compared to plain-old balloon angioplasty. Nonetheless in the majority of those trials, the bailout stenting rate increased with lesion complexity, albeit it in long or heavily calcified lesions due to flow-limiting dissections, elastic recoil or the calcium barrier preventing adequate drug uptake. There is a need for vessel preparation in order to ameliorate drug delivery, especially in complex lesions. Multiple devices are available to prepare even the most challenging lesions for drug uptake or stenting, by achieving maximal luminal gain and by minimizing dissections. This review aims to give an overview of the most common modalities for vessel preparation in the superficial femoral artery beside plain old balloon angioplasty together with an overview of the current literature of each device in the superficial femoral artery.

Abstract
An ageing population and the increasing prevalence of cardiovascular risk factors have aggravated the burden of peripheral artery disease (PAD). Despite advances in the pharmacological treatment of atherosclerosis, many patients with symptomatic PAD require invasive procedures to reduce the symptoms of claudication, salvage tissue and prevent amputation and subsequent disability in those with critical limb ischaemia. After significant advances in endovascular treatment over the past two decades, these techniques are widely accepted as first-choice treatment in the majority of patients with PAD. However, in patients with severely calcified lesions, standard endovascular treatment such as plain or drug-coated balloon (DCB) angioplasty may fail due to vessel recoil or severe dissection in the acute setting, and intimal hyperplasia in the long term. With the use of percutaneous plaque modification and debulking techniques based on atherectomy, such calcified lesions can be tackled more easily after removal or fragmentation of atherosclerotic plaque. More homogeneous balloon expansion at lower pressures can be achieved after atherectomy, which reduces barotrauma while allowing better drug delivery to the vessel wall during DCB angioplasty avoids the need for stent placement. There are four principal methods of direct atherectomy available at the present time: directional atherectomy, rotational atherectomy, orbital atherectomy and hybrid atherectomy. In this article, we provide a short overview of these techniques and the current evidence from clinical trials to support their use.

Abstract
Objective: The optimal antithrombotic regimen in peripheral arterial disease (PAD) is not known, leading to significant variations in antithrombotic treatment protocols in randomized trials and clinical practice. In device trials, antithrombotic regimens in patients receiving peripheral vascular interventions have not been clearly reported on. This review summarizes and discusses the most recent evidence on this topic to provide a potential guide to clinical practice. Methods: A search of the literature was done for publications that reported outcomes of major PAD device trials. Reported outcomes and various antithrombotic regimens were studied. Results: Use of antithrombotic therapy varied significantly between various device trials. Reporting of antithrombotic regimens at the time of follow-up is lacking. Conclusion: Outcome data on optimal antithrombotic regimens are presently lacking largely due to the significant heterogeneity and underreporting of antithrombotic regimens at follow-up among prior clinical trials. Standardization and reporting of precise antithrombotic regimens at various points of follow-up in device trials of patients with PAD should be attempted so as to minimize differences in treatment patterns when evaluating new devices.

Abstract
Objective Percutaneous revascularization for patients with peripheral arterial disease has become a treatment of choice for many symptomatic patients. The presence of severe arterial calcification presents many challenges for successful revascularization. Atherectomy is an adjunctive treatment option for patients with severe calcification undergoing percutaneous intervention. We sought to analyze the impact of atherectomy on in-hospital outcomes, length of stay, and cost in the percutaneous treatment of peripheral arterial disease. Methods Patients with lower extremity peripheral arterial disease undergoing percutaneous revascularization were assessed, utilizing the National Inpatient Sample (2012-2014) and appropriate International Classification of Diseases, 9th Revision, Clinical Modification diagnostic and procedural codes. Patients who were not treated with atherectomy ( n = 51,037) were compared to those treated with atherectomy ( n = 11,408). Propensity score-matched analysis was performed to address baseline differences. Results After performing propensity score-matched analysis, 11,037 patients were included in each group. Utilization of atherectomy was associated with lower in-hospital mortality (2% vs. 1.4% p = 0.0006). All secondary outcomes were lower when using atherectomy except acute renal failure. Length of stay was slightly lower when using atherectomy (7.2 vs. 7.0 days, p = 0.0494). However, median cost was higher in patients treated with atherectomy ($21,589 vs. $24,060, p = <0.0001). Conclusion The use of atherectomy was associated with significantly decreased in-hospital mortality, adverse events, and length of stay. Though, cost associated with atherectomy use is increased, this is offset by decreased in-hospital adverse outcomes. Appropriate use of atherectomy devices is an important tool in revascularization of peripheral arterial disease in select patients.

Abstract
AIMS The crossing of chronic total occlusions (CTOs) is the key step for an endovascular treatment. The Ocelot system is a novel device that combines a steerable drilling tip with optical coherence tomography (OCT) technology. It provides intraluminal imaging to help the crossing of CTOs in the femoropopliteal segment. Aim of the study was to determine early and midterm results after recanalization with this device. METHODS AND RESULTS During a period of 16 months, 84 CTOs were treated using the Ocelot system and prospectively registered. The primary end points were technical success and the primary and secondary patency of the lesion. Risk factors associated with early and midterm results were also analyzed. In all, 58 (69.0%) lesions were treated for intermittent claudication, 26 (31.0%) for critical limb ischemia, 34 (40.5%) were classified as Trans-Atlantic Inter-Society Consensus II D lesions, and 22 (26.2%) showed severe calcifications. The technical success rate was 72.6%. During 36 months of follow-up (mean 25.9), there were 10 reinterventions. The primary and secondary patency at 36 months were 54.2% and 68.1%, respectively. CONCLUSIONS In our experience, the Ocelot system would appear to be a safe and effective tool for increasing the applicability of endovascular techniques. However, the midterm results did not show drastic improvement.
