Comparison of Clinical Effectiveness and Safety of Drug-Coated Balloons versus Percutaneous Transluminal Angioplasty in Arteriovenous Fistulae: A Review of Systematic Reviews and Updated Meta-Analysis. J Vasc Interv Radiol 2024; 35:949-962.e13. [PMID: 38554948 DOI: 10.1016/j.jvir.2024.03.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 02/14/2024] [Accepted: 03/23/2024] [Indexed: 04/02/2024] Open
Abstract
PURPOSE To evaluate the clinical effectiveness and safety of drug-coated balloons (DCBs) compared with those of percutaneous transluminal angioplasty (PTA) for arteriovenous fistula (AVF) stenosis via a review of systematic reviews (SRs) and an update of the current meta-analysis. MATERIALS AND METHODS Literature was searched to retrieve SRs comparing DCBs and PTA for AVFs. A narrative review of SRs and pooled analysis were performed. RESULTS Eleven SRs were included. DCBs demonstrated favorable outcomes at 6 and 12 months compared with PTA, with improved patency in 7 SRs and a trend toward favorable outcomes without statistical significance in 3 SRs. Target lesion revascularization (TLR) was reported in 3 SRs; 2 reviews reported a significantly lower incidence in the DCB group than in the PTA group, whereas 1 review reported no significant differences at 12 months. Four studies reporting all-cause mortality revealed no significant difference between the 2 treatments. In the updated meta-analysis including 23 studies, DCBs demonstrated improved primary patency at 6 months (risk ratio [RR], 1.27; 95% CI, 1.07-1.50) and 12 months (RR, 1.36; 95% CI, 1.19-1.55) and were associated with a lower incidence of TLR at 6 months (RR, 0.54; 95% CI, 0.41-0.73) and 12 months (RR, 0.78; 95% CI, 0.62-0.99). There was no difference in mortality between the 2 groups for 24 months. CONCLUSIONS A review of SRs and meta-analysis update revealed the consistent benefits of DCBs over PTA in treating AVFs in terms of primary patency and TLR. Compared with PTA, DCBs do not increase mortality risk.

Abstract
While blood-contacting materials are widely deployed in medicine in vascular stents, catheters, and cannulas, devices fail in situ because of thrombosis and restenosis. Furthermore, microbial attachment and biofilm formation is not an uncommon problem for medical devices. Even incremental improvements in hemocompatible materials can provide significant benefits for patients in terms of safety and patency as well as substantial cost savings. Herein, a novel but simple strategy is described for coating a range of medical materials, that can be applied to objects of complex geometry, involving plasma-grafting of an ultrathin hyperbranched polyglycerol coating (HPG). Plasma activation creates highly reactive surface oxygen moieties that readily react with glycidol. Irrespective of the substrate, coatings are uniform and pinhole free, comprising O─C─O repeats, with HPG chains packing in a fashion that holds reversibly binding proteins at the coating surface. In vitro assays with planar test samples show that HPG prevents platelet adhesion and activation, as well as reducing (>3 log) bacterial attachment and preventing biofilm formation. Ex vivo and preclinical studies show that HPG-coated nitinol stents do not elicit thrombosis or restenosis, nor complement or neutrophil activation. Subcutaneous implantation of HPG coated disks under the skin of mice shows no evidence of toxicity nor inflammation.

Vascul Pharmacol 2024; 155:107366. [PMID: 38479462 DOI: 10.1016/j.vph.2024.107366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 02/24/2024] [Accepted: 03/08/2024] [Indexed: 03/22/2024]
Abstract
Below-the-knee (infrapopliteal) atherosclerotic disease, which presents as chronic limb-threatening ischemia (CLTI) in nearly 50% of patients, represents a treatment challenge when it comes to the endovascular intervention arm of management. Due to reduced tissue perfusion, patients usually experience pain at rest and atrophic changes correlated to the extent of the compromised perfusion. Unfortunately, the prognosis remains unsatisfactory with 30% of patients requiring major amputation and a mortality rate of 25% within 1 year. To date, randomized multicentre trials of endovascular intervention have shown that drug-eluting stents (DES) increase patency rate and lower target lesion revascularization rate compared to plain balloon angioplasty and bare-metal stents. The majority of these trials recruited patients with focal infrapopliteal lesions, while most patients requiring endovascular intervention have complex and diffuse atherosclerotic disease. Moreover, due to the nature of the infrapopliteal arteries, the use of long DES is limited. Following recent results of drug-coated balloons (DCBs) in the treatment of femoropopliteal and coronary arteries, it was hoped that similar effective results would be achieved in the infrapopliteal arteries. In reality, multicentre trials have failed to support the proposed hypothesis and no advantage was found in using DCBs in comparison to plain balloon angioplasty. This review aims to explore anatomical, physiological and pathological differences between lesions of the infrapopliteal and coronary arteries to explain the differences in outcome when using DCBs.

Abstract
OBJECTIVE Local Liquid drug (LLD) delivery devices have recently emerged as a novel approach to treat peripheral arterial disease. This systemic review aims to identify and evaluate the clinical utility of the most commonly used delivery devices. METHODS A systemic review was performed using the Medical Subjects Heading terms of "drug delivery," "liquid," "local," and "cardiovascular disease" in PubMed, Google Scholar, and Scopus. RESULTS Four commonly used delivery devices were identified, including (1) the Bullfrog Micro-Infusion Device, (2) the ClearWay RX Catheter, (3) the Occlusion Perfusion Catheter, and (4) the Targeted Adjustable Pharmaceutical Administration. All have shown to successfully deliver liquid therapeutic into the target lesion and have exhibited favorable safety and efficacy profiles in preclinical and clinical trials. The LLD devices have the ability to treat very long or multiple lesions with a single device, providing a more economical option. The safety profile in LLD clinical studies is also favorable in view of recent concerns regarding adverse events with crystalline-paclitaxel-coated devices. CONCLUSION There is clear clinical evidence to support the concept of local liquid delivery to treat occlusive arterial disease. CLINICAL IMPACT The 'leave nothing behind' strategy has been at the forefront of the most recent innovations in the field of interventional cardiology and vascular interventions. Although drug coated balloons have overcome limitations associated with plain old balloon angioplasty and peripheral stents, recent safety concerns and cost considerations have impacted their usage. In this review, various liquid drug delivery devices are presented, showcasing their capabilities and success in both preclinical and clinical settings. These innovative liquid delivery devices, capable of targeted delivery and their ability to be re-used for multiple treatment sites, may provide solutions for current unmet clinical needs.

Ann Vasc Surg 2024; 101:164-178. [PMID: 38154491 PMCID: PMC11293953 DOI: 10.1016/j.avsg.2023.11.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/15/2023] [Accepted: 11/17/2023] [Indexed: 12/30/2023]
Abstract
BACKGROUND The aims of this study were: i) to assess fragility indices (FIs) of individual randomized controlled trials (RCTs) that compared paclitaxel-based drug-coated balloons (DCBs) or drug-eluting stents (DESs) versus standard endovascular devices, and ii) to meta-analyze mid-term and long-term safety and efficacy outcomes from available RCT data while also estimating the FI of pooled results. METHODS This systematic review has been registered in the PROSPERO public database (CRD42022304326 http://www.crd.york.ac.uk/PROSPERO). A query of PubMed (Medline), EMBASE (Excerpta Medical Database), Scopus, and CENTRAL (Cochrane Central Register of Controlled Trials) databases was performed to identify eligible RCTs. Rates of primary patency (PP) and target lesion revascularization (TLR) were assessed as efficacy outcomes, while lower limb amputation (LLA) consisting of major amputation that is. below or above the knee and all-cause mortality were estimated as safety outcomes. All outcomes were pooled with a random effects model to account for any clinical and study design heterogeneity. The analyses were performed by dividing the RCTs according to their maximal follow-up length (mid-term was defined as results up to 2-3 years, while long-term was defined as results up to 4-5 years). For each individual outcome, the FI and reverse fragility index (RFI) were calculated according to whether the outcome results were statistically significant or not, respectively. The fragility quotient (FQ) and reverse fragility quotient (RFQ), which are the FI or RFI divided by the sample size, were also calculated. RESULTS A total of 2,337 patients were included in the systematic review and meta-analysis. There were 2 RCTs examining DES devices and 14 RCTs evaluating different DCBs. For efficacy outcomes, there was evidence that paclitaxel-based endovascular therapy increased the PP rate and reduced the TLR rate at mid-term, with a calculated pooled risk ratio (RR) of 1.66 for patency (95% CI, 1.55-1.86; P < 0.001), with a corresponding number needed-to-treat (NNT) of 3 patients (95% CI, 2.9-3.8) and RR of 0.44 for TLR (95% CI, 0.35-0.54; P = 0.027), respectively. Similarly, there was evidence that paclitaxel-based endovascular therapy both increased PP and decreased TLR rates at long-term, with calculated pooled RR values of 1.73 (95% CI, 1.12-2.61; P = 0.004) and 0.53 (95% CI, 0.45-0.62; P = 0.82), respectively. For safety outcomes, there was evidence that paclitaxel-based endovascular therapy increased all-cause mortality at mid-term, with a calculated pooled RR of 2.05 (95% CI, 1.21-3.24). However, there was no difference between treatment arms in LLA at mid-term (95% CI, 0.1-2.7; P = 0.68). Similarly, neither all-cause mortality nor LLA at long-term differed between treatment arms, with a calculated pooled RR of 0.66, 1.02 (95% CI, 0.31-3.42) and 1.02 (95% CI, 0.30-5.21; P = 0.22), respectively. The pooled estimates of PP at mid-term were robust (FI = 28 and FQ = 1.9%) as were pooled rates of TLR (FI = 18 and FQ = 0.9%). However, when safety outcomes were analyzed, the robustness of the meta-analysis decreased significantly. In fact, the relationship between the use of paclitaxel-coated devices and all-cause mortality at mid-term showed very low robustness (FI = 4 and FQ = 0.2%). At 5 years, only the benefit of paclitaxel-based devices to reduce TLR remained robust, with an FI of 32 and an FQ of 3.1%. CONCLUSIONS The data supporting clinical efficacy endpoints of RCTs that examined paclitaxel-based devices in the treatment of femoral-popliteal arterial occlusive disease were robust; however, the pooled safety endpoints were highly fragile and prone to bias due to loss of patient follow-up in the original studies. These findings should be considered in the ongoing debate concerning the safety of paclitaxel-based devices.

Abstract
PURPOSE This follow-up study was designed as a reopen of the completed Freeway Stent Study and collected mortality and clinical outcome data for at least 5 years after enrollment to evaluate long-term patient safety and treatment efficacy. The primary study enrolled 204 patients with stenosis or occlusion in the superficial femoral artery and proximal popliteal artery. Patients were randomized to primary nitinol stenting followed by standard PTA or primary nitinol stenting followed by FREEWAY™ paclitaxel-eluting balloon PTA. METHODS Previous patients were recontacted by phone or during a routine hospital visit, and medical records were reviewed. Vital and clinical status information was collected. RESULTS No increased late mortality was observed at 5 years, with an all-cause mortality rate of 12.0% in the FREEWAY drug-eluting balloon group versus 15.0% in the non-paclitaxel PTA group. No accumulation of any cause of death was observed in either group, nor was there any correlation with the dose of paclitaxel used. Freedom from clinically driven target lesion revascularization at 5 years was significantly higher in the FREEWAY drug eluting balloon group (85.3%) compared to standard PTA group (72.7%) Log-rank p = 0.032. CONCLUSION The safety results presented support the recent conclusions that the use of paclitaxel technology does not lead to an increase in mortality. At the same time, the efficacy results clearly demonstrate that the potential benefits of drug-eluting balloon treatment are maintained over a 5-year period.

[PMID: 38092496 DOI: 10.1016/j.jcin.2023.10.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/30/2023] [Accepted: 10/30/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND There is a scarcity of published head-to-head comparisons between different paclitaxel-coated angioplasty balloons. More prospective safety data to support the health care economic reimbursement processes are needed. OBJECTIVES The aim of this study was to report the safety and efficacy of the Passeo-18 Lux drug-coated balloon (DCB) (Biotronik AG) for the treatment of symptomatic peripheral artery disease caused by stenosis, restenosis, or occlusion of the femoral and/or popliteal arteries. METHODS A total of 302 patients were randomized 1:1 and assigned to the Passeo-18 Lux DCB (study device) group or the IN.PACT Admiral DCB (control device, Medtronic Vascular) group for testing of noninferiority. The primary efficacy endpoint was freedom from clinically driven target lesion revascularization at 12 months. The primary safety endpoint was a composite of freedom from device-/procedure-related death through 30 days postindex procedure, major target limb amputation, and clinically driven target vessel revascularization at 12 months. RESULTS At 12 months, 130 of 134 patients in the IN.PACT Admiral group had freedom from clinically driven target lesion revascularization (97.0%) compared with 137 of 141 patients in the Passeo-18 Lux group (97.2%). The primary safety endpoint showed 96.3% in the control group vs 95.7% in the study device group. The null hypothesis of inferiority on both efficacy and safety was rejected. The Kaplan-Meier estimate of primary patency at 1 year was 88.7% in the control arm vs 91.5% in the study device arm. CONCLUSIONS The Passeo-18 Lux and the IN.PACT Admiral DCBs demonstrate comparable results with excellent effectiveness and safety through 12 months for femoropopliteal interventions.

Mortality in randomised controlled trials using paclitaxel-coated devices for femoropopliteal interventional procedures: an updated patient-level meta-analysis. Lancet 2023; 402:1848-1856. [PMID: 37890499 DOI: 10.1016/s0140-6736(23)02189-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 09/22/2023] [Accepted: 09/27/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Numerous randomised clinical trials and real-world studies have supported the safety of paclitaxel-coated devices for the treatment of femoropopliteal occlusive disease. However, a 2018 summary-level meta-analysis suggested an increased mortality risk for paclitaxel-coated devices compared with uncoated control devices. This study presents an updated analysis of deaths using the most complete and current data available from pivotal trials of paclitaxel-coated versus control devices. METHODS Ten trials comparing paclitaxel-coated versus control devices were included in a patient-level pooled analysis. Cox regression models were used to evaluate the effect of paclitaxel exposure on risk of death in both intention-to-treat (ITT; primary analysis) and three as-treated analysis sets accounting for treatment group crossover at the index procedure and over time. The effect of paclitaxel dose and baseline covariates were also evaluated. FINDINGS A total of 2666 participants were included with a median follow-up of 4·9 years. No significant increase in deaths was observed for patients treated with paclitaxel-coated devices. This was true in the ITT analysis (hazard ratio [HR] 1·14, 95% CI 0·93-1·40), the as-treated analysis (HR 1·13, 95% CI 0·92-1·39), and in two crossover analyses: 1·07 (0·87-1·31) when late crossovers were censored and 1·04 (0·84-1·28) when crossovers were analysed from the date of paclitaxel exposure. There was no significant effect of paclitaxel dose on mortality risk. INTERPRETATION This meta-analysis found no association between paclitaxel-coated device exposure and risk of death, providing reassurance to patients, physicians, and regulators on the safety of paclitaxel-coated devices.

Abstract
Registry Assessment of Peripheral Interventional Devices (RAPID) initiated the Pathways Program to provide a transparent, collaborative forum in which to pursue insights into multiple unresolved questions on benefit-risk of paclitaxel-coated devices, including understanding the basis of the mortality signal, without a demonstrable potential biological mechanism, and whether the late mortality signal could be artifact intrinsic to multiple independent prospective randomized data sources that did not prespecify death as a long-term end point. In response to the directive, the LEAN-Case Report Form working group focused on enhancements to the RAPID Phase I Minimum Core Data set through the addition of key clinical modifiers that would be more strongly linked to longer-term mortality outcomes after peripheral arterial disease intervention in the drug-eluting device era, with the goal to have future mortality signals more accurately examined.

Abstract
OBJECTIVE Drug eluting stents (DES) might improve the results of stenting in the femoropopliteal (FP) segment, but randomized data between DES and BMS in the treatment of patients with chronic limb threatening ischemia (CLTI) is lacking. The aim of this study was to perform a randomized comparison, between DES and bare metal stent (BMS) implantation in a subgroup of CLTI patients with lesions in the superficial femoral artery (SFA) and the P1-P2 portion of the popliteal artery. METHODS Patients presenting with CLTI scheduled for endovascular treatment of FP lesions were randomly assigned by blinded envelopes 1:1 in a single blinded, parallel group design to DES or BMS after lesion crossing. Primary endpoints were target lesion revascularization (TLR) at 12 and 24 months and primary patency at 12 and 24 months. Secondary endpoints were technical success (TS), clinical success, secondary patency at 12 and 24 months, limb salvage, serious adverse events (SAE) at 24 month and survival at five years. RESULTS A total of 48 CLTI patients and 49 limbs, were enrolled, 22 in the BMS group and 27 in the DES group. Demographics, comorbidities, and Rutherford class were similar in both treatment arms. The overall rate of total occlusions was 96% and the corresponding overall median lesion length was 240 mm. No patients were lost to follow up. No significant differences were detected between groups regarding TLR and primary patency. The overall primary patency at 12 and 24 months was 42.9% and 36.7% respectively and the overall freedom from TLR was 67.3% and 61.2% respectively. The results in the two groups were also similar regarding secondary outcomes. CONCLUSIONS This single centre, randomized study could not demonstrate superiority of DES compared to BMS when treating long FP lesions in patients with CLTI but was limited by insufficient patient inclusion.

Abstract
Arteriovenous fistula (AVF) stenosis is a common problem leading to dialysis access dysfunction. The conventional balloon (CB) is the most commonly used device during angioplasty but suffers from poor durability of results due to neointimal hyperplasia-mediated recurrence. The drug-coated balloon (DCB) is an adjunct to balloon angioplasty that reduces neointimal hyperplasia, thereby improving post-angioplasty patency. Despite the heterogeneity of DCB clinical trials to date, the evidence suggests that DCBs of different brands are not necessarily equal, and that patient selection, adequate lesion preparation and proper DCB procedural technique are important to realize the benefit of DCB angioplasty.

Abstract
As the number of patients affected by peripheral arterial disease continues to increase, new technical approaches and devices have been developed to provide effective and durable treatment options that will lead to improved outcomes. While the mainstay of endovascular intervention remains mostly balloon-based, several innovative techniques and technologies are in development that may provide new solutions. This review highlights recent endovascular advancements in the management of chronic limb-threatening ischemia and additional adjunctive devices that are needed to improve lesion patency, reduce the need for reintervention, and lead to better patient-centered functional outcomes.

Abstract
BACKGROUND We aimed to describe patient and limb outcomes in the decade after endovascular revascularization for chronic lower-extremity peripheral artery disease (PAD). METHODS We assessed outcomes in patients having endovascular revascularization of the superficial femoral artery in two centers between 2003 and 2011 and followed for a median 9.3 (25-75%: 6.8, 11.1) years. Outcomes included death, myocardial infarction, stroke, repeat limb revascularizations, and amputations. We used competing risks analysis with clustering by patient to determine the hazard ratios (HR) and 95% CI for patients, and procedural characteristics for cause of death, cardiovascular events, and major adverse limb events (MALE). RESULTS There were 253 index limb revascularizations in 202 patients followed for a median 9.3 years. Patients had intensive medical treatment with 90% on statins and 80% on beta-blockers. During follow up there were 57 (28%) cardiovascular deaths and 62 (31%) noncardiovascular deaths. Of the 253 limbs, 227 (90%) were free of MALE over follow up and 93 (37%) had MALE or minor repeat revascularization. In multivariable models, cardiovascular death significantly associated with critical limb ischemia (HR = 3.21, 95% CI = 1.84, 5.61) and noncardiovascular death with chronic kidney disease (HR = 2.69, 95% CI = 1.68, 4.30), and smoking (HR = 2.75, 95% CI = 1.01, 7.52). MALE or minor repeat revascularization associated with critical limb ischemia (HR = 1.43, 95% CI = 0.84, 2.43), smoking (HR = 2.49, 95% CI = 1.26, 4.90), and lesion length > 200 mm (HR = 1.51, 95% CI = 0.98, 2.33). CONCLUSIONS Among patients with intensive medical therapy, the risk of noncardiovascular death was high and similar to cardiovascular death. Endovascular intervention can have acceptable long-term results. Future studies should evaluate strategies to reduce both cardiovascular and noncardiovascular deaths.

Abstract
Background There is a need to evaluate the latest information regarding a potential late safety signal in patients treated with paclitaxel-coated devices for peripheral artery disease. We evaluated the 5-year all-cause mortality rate of the Stellarex drug-coated balloon (DCB) compared with percutaneous transluminal angioplasty (PTA). Methods An independent third-party performed a patient-level meta-analysis of the pooled ILLUMENATE Pivotal and EU randomized controlled trials. The primary outcome was time to death. Kaplan-Meier estimates of all-cause mortality were compared with the log-rank test. Predictors of mortality were assessed with Cox proportional hazard modeling. A blinded clinical events committee adjudicated all serious adverse events (including death). The follow-up was 60 months. Results A total of 589 patients were followed for a median of 4.9 years (IQR, 4.8, 5.1 years); 419 were randomized to Stellarex DCB and 170 to PTA. Vital status was obtained for 93.8%. The 5-year Kaplan-Meier estimates of freedom from all-cause death were 80.4% (95% CI, 76.7%-84.3%) in the Stellarex DCB arm versus 80.4% (95% CI, 74.3%-86.5%) in the PTA arm (log-rank, P = .7754). There was no difference in all-cause mortality when stratified by paclitaxel dose terciles. Predictors of mortality included renal insufficiency, reference vessel diameter, age, and lesion length, but not paclitaxel dose nor paclitaxel exposure. Conclusions There was no difference in all-cause mortality between the Stellarex DCB and PTA through the final 5-year follow-up window of 2 ILLUMENATE randomized controlled trials. These long-term data build on the previously reported safety of the Stellarex DCB for treating symptomatic femoropopliteal peripheral artery disease.

Abstract
PURPOSE To investigate the real-world safety of paclitaxel (PTX)-coated devices for treating lower extremity peripheral artery disease using a commercial claims database. MATERIALS AND METHODS Data from FAIR Health, the largest commercial claims data warehouse in the United States, were used for this study. The study consisted of patients who underwent femoropopliteal revascularization procedures between January 1, 2015, and December 31, 2019, with PTX and non-PTX devices. The primary outcome was 4-year survival following treatment. The secondary outcomes included 2-year survival, 2- and 4-year freedom from amputation, and repeat revascularization. Propensity score matching was used to minimize confounding, and the Kaplan-Meier methods were used to estimate survival. RESULTS A total of 10,832 procedures were included in the analysis, including 4,962 involving PTX devices and 5,870 involving non-PTX devices. PTX devices were associated with a reduced hazard of death following treatment at 2 and 4 years (hazard ratio [HR], 0.74 [95% confidence interval {CI}, 0.69-0.79]; P <.05, and HR, 0.89 [95% CI, 0.77-1.02]; log-rank P =.018, respectively). The risk of amputation was also lower following treatment with PTX devices than with non-PTX devices at 2 and 4 years (HR, 0.82 [95% CI, 0.76-0.87]; P =.02, and HR, 0.77 [95% CI, 0.67-0.89]; log-rank P =.01, respectively). In addition, the odds of repeat revascularization were similar with PTX and non-PTX devices at 2 and 4 years. CONCLUSIONS In the real-world commercial claims database, no short- or long-term signal for increased mortality or amputations was observed following treatment with PTX devices.

Endovascular revascularization strategies for aortoiliac and femoropopliteal artery disease: a meta-analysis. Eur Heart J 2023; 44:935-950. [PMID: 36721954 PMCID: PMC10011342 DOI: 10.1093/eurheartj/ehac722] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 10/24/2022] [Accepted: 11/22/2022] [Indexed: 02/02/2023] Open
Abstract
AIMS Optimal endovascular management of intermittent claudication (IC) remains disputed. This systematic review and meta-analysis compares efficacy and safety outcomes for balloon angioplasty (BA), bare-metal stents (BMS), drug-coated balloons (DCB), drug-eluting stents (DES), covered stents, and atherectomy. METHODS AND RESULTS Electronic databases were searched for randomized, controlled trials (RCT) from inception through November 2021. Efficacy outcomes were primary patency, target-lesion revascularization (TLR), and quality-of-life (QoL). Safety endpoints were all-cause mortality and major amputation. Outcomes were evaluated at short-term (<1 year), mid-term (1-2 years), and long-term (≥2 years) follow-up. The study was registered on PROSPERO (CRD42021292639). Fifty-one RCTs enrolling 8430 patients/lesions were included. In femoropopliteal disease of low-to-intermediate complexity, DCBs were associated with higher likelihood of primary patency [short-term: odds ratio (OR) 3.21, 95% confidence interval (CI) 2.44-4.24; long-term: OR 2.47, 95% CI 1.93-3.16], lower TLR (short-term: OR 0.33, 95% CI 0.22-0.49; long-term: OR 0.42, 95% CI 0.29-0.60) and similar all-cause mortality risk, compared with BA. Primary stenting using BMS was associated with improved short-to-mid-term patency and TLR, but similar long-term efficacy compared with provisional stenting. Mid-term patency (OR 1.64, 95% CI 0.89-3.03) and TLR (OR 0.50, 95% CI 0.22-1.11) estimates were comparable for DES vs. BMS. Atherectomy, used independently or adjunctively, was not associated with efficacy benefits compared with drug-coated and uncoated angioplasty, or stenting approaches. Paucity and heterogeneity of data precluded pooled analysis for aortoiliac disease and QoL endpoints. CONCLUSION Certain devices may provide benefits in femoropopliteal disease, but comparative data in aortoiliac arteries is lacking. Gaps in evidence quantity and quality impede identification of the optimal endovascular approach to IC.

The Relationship Between Hospital Procedure Volume and Outcomes After Endovascular or Open Surgical Revascularisation for Peripheral Arterial Disease: An Analysis of Health Insurance Claims Data. Eur J Vasc Endovasc Surg 2023; 65:370-378. [PMID: 36464221 DOI: 10.1016/j.ejvs.2022.11.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 08/22/2022] [Accepted: 11/29/2022] [Indexed: 12/03/2022]
Abstract
OBJECTIVE There is a paucity of data on the relationship between hospital procedure volume and outcomes after inpatient treatment of symptomatic peripheral arterial disease (PAD). This study aimed to generate meaningful hypotheses to support the ongoing discussion. METHODS Data derived from BARMER, Germany's second largest insurance provider, were linked with nationwide hospital procedure volumes from mandatory hospital quality reports. All endovascular (EVR) and open surgical revascularisations (OSR) provided to patients (≥ 40 years) with symptomatic PAD between 1 January 2013 and 31 December 2018 were included. Hospital volume was defined as the number of procedures performed by a hospital in the previous calendar year (in quartiles). Freedom from re-intervention, amputation, and overall mortality rate within 12 months after discharge were analysed using multivariable Cox proportional hazards models. In hospital mortality was determined by generalised estimating equations logistic regression models. RESULTS There were 88 187 revascularisations (72.4% EVR; EVR: 72.7 years and 45.2% females; OSR: 71.9 years and 41.9% females) registered by 668 hospitals. No statistically significant association was found between 12 month freedom from re-intervention and hospital volume (EVR: 4; quartile HR 1.05; 95% CI 0.94 - 1.16. OSR: 4; quartile HR 1.05; 95% CI 0.92 - 1.21). Patients with OSR had a decreased hazard of 12 month mortality in a high volume hospital compared with a low volume hospital (HR 0.85; 95% CI 0.73 - 0.98), but not with EVR (HR 1.03; 95% CI 0.91 - 1.16). Patients who were treated in hospitals with highest volumes showed decreased hazards of 12 month freedom from amputation when compared with low volume hospitals (EVR: HR 0.72; 95% CI 0.52 - 0.99. OSR: HR 0.61; 95% CI 0.44 - 0.85). CONCLUSION This large retrospective analysis of insurance claims suggests that higher procedure volume is associated with lower major amputation rates, although there is a need for standardisation of the definition of volume stratification. Future studies should address the impact of subsequent outpatient care and surveillance to further examine the complex interaction between treatment and outcomes.

J Vasc Surg 2023; 77:1742-1750. [PMID: 36754247 DOI: 10.1016/j.jvs.2023.01.195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/17/2023] [Accepted: 01/20/2023] [Indexed: 02/08/2023]
Abstract
OBJECTIVE Data regarding the safety and efficacy of paclitaxel (PTX)-coated peripheral arterial devices for femoropopliteal artery (FPA) atherosclerotic disease is derived from studies that mainly evaluated patients with claudication. Outcomes of PTX treatment for patients with chronic limb-threatening ischemia (CLTI) is incompletely defined. This study compares outcome in patients with CLTI treated with and without PTX. METHODS We retrospectively studied patients who underwent FPA intervention for an indication of CLTI in the Vascular Quality Initiative peripheral vascular intervention database from 2016 to 2020. Patients who had concomitant iliac or tibial interventions were included. One limb per patient was studied. Propensity score matching based on demographics, comorbidities, indication, and pharmacological therapy was performed to generate balanced cohorts. Kaplan-Meier survival analysis and multivariate Cox regression compared limb salvage, overall survival, primary patency, and major adverse limb events (MALE) between patients treated with and without PTX. RESULTS Demographics, comorbidities, indications, and procedural details were similar between 14,065 PTX and 14,065 non-PTX propensity-matched patients. Kaplan-Meier analysis at 18-month follow-up demonstrated that the PTX group compared with the non-PTX group had a significantly higher rates of limb salvage (89.2% vs 86.5%; P < .001), primary patency (80.3% vs 76.9%; P < .001), and freedom from MALE (72.6% vs 67.9%; P < .001). Multivariate analysis also showed that PTX treatment was associated with a lower risk of major amputation (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.67-0.82; P < .001), loss of primary patency (HR, 0.80; 95% CI, 0.74-0.87; P < .001), and MALE (HR, 0.77; 95% CI, 0.72-0.82; P < .001). Overall, 21% of patients had a prior ipsilateral peripheral vascular intervention. Removing these patients from the analysis yielded similar results at 18 months. Overall survival at 54 months was not statistically different between the PTX and non-PTX groups in the overall cohort (73.5 vs 71.3%; P = .07), but significant in the de-novo treated patients (73.9% vs 70.7%; P = .02).Multivariate analyses showed a lower mortality risk in the PTX patients (HR, 0.93; 95% CI, 0.87-0.98; P = .02). CONCLUSIONS FPA intervention with a PTX-coated device is associated with improved limb salvage, primary patency, and freedom from MALE at the 18-month follow-up compared with uncoated devices. This benefit was not associated with an increase in all-cause mortality out to 4.5 years. Further study is necessary to determine the optimal role for PTX in the treatment of the FPA for patients with CLTI and to understand its long-term outcome.

Editor's Choice - Real World Study of Mortality After the Use of Paclitaxel Coated Devices in Peripheral Vascular Intervention. Eur J Vasc Endovasc Surg 2023; 65:131-140. [PMID: 36007713 PMCID: PMC9839562 DOI: 10.1016/j.ejvs.2022.08.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 07/27/2022] [Accepted: 08/09/2022] [Indexed: 01/17/2023]
Abstract
OBJECTIVE This observational cohort study examined outcomes after peripheral vascular intervention (PVI) with paclitaxel coated devices (PCD) and non-PCD, and evaluated heterogeneity of treatment effect in populations of interest. METHODS The study included patients undergoing percutaneous transluminal angioplasty and or stent placement between 1 October 2015 and 31 December 2018 in the Vascular Quality Initiative Registry linked to Medicare claims. It determined differences in patient mortality and ipsilateral major amputation after PVI with PCD and non-PCD using Kaplan-Meier analyses and Cox regressions with inverse probability weighting in three cohorts: (A) patients treated for femoropopliteal or infrapopliteal occlusive disease with or without any other concurrent treatment (n = 11 452); (B) those treated for isolated superficial femoral or popliteal artery disease (n = 5 519); and (C) patients with inclusion criteria designed to approximate RCT populations (n = 2 278). RESULTS The mean age of patients was 72.3 (SD = 10.9) years, and 40.6% were female. In cohort A, patients receiving PCD had a lower mortality rate (HR 0.88, 95% CI 0.79 - 0.98) than those receiving non-PCD. There was no significant difference in mortality between groups in cohort B (HR 0.91, 95% CI 0.80 - 1.04) and cohort C (HR 1.10, 95% CI 0.84 - 1.43). Patients receiving PCD did not have a significantly elevated risk of major amputation compared with those receiving non-PCD (cohort A: HR 0.84, 95% CI 0.70 - 1.00; cohort B: HR 0.84, 95% CI 0.67 - 1.06; and cohort C: HR 1.05, 95% CI 0.51 - 2.14). CONCLUSION No increased patient mortality or major amputation was found at three years after PVI with PCD vs. non-PCD in this large, linked registry claims study, after accounting for heterogeneity of treatment effect by population. The analysis and results from three cohorts intended to mirror the cohorts of previous studies provide robust and niche real world evidence on PCD safety and help to understand and reconcile previously discrepant findings.

Abstract
BACKGROUND A clear patency benefit of a drug-eluting stent (DES) over bare metal stents (BMSs) for treating peripheral artery disease of the femoropopliteal segment has not been definitively demonstrated. The EMINENT study (Trial Comparing Eluvia Versus Bare Metal Stent in Treatment of Superficial Femoral and/or Proximal Popliteal Artery) was designed to evaluate the patency of the Eluvia DES (Boston Scientific, Marlborough, MA), a polymer-coated paclitaxel-eluting stent, compared with BMSs for the treatment of femoropopliteal artery lesions. METHODS EMINENT is a prospective, randomized, controlled, multicenter European study with blinded participants and outcome assessment. Patients with symptomatic peripheral artery disease (Rutherford category 2, 3, or 4) of the native superficial femoral artery or proximal popliteal artery with stenosis ≥70%, vessel diameter of 4 to 6 mm, and total lesion length of 30 to 210 mm were randomly assigned 2:1 to treatment with DES or BMS. The primary effectiveness outcome was primary patency at 12 months, defined as independent core laboratory-assessed duplex ultrasound peak systolic velocity ratio ≤2.4 in the absence of clinically driven target lesion revascularization or surgical bypass of the target lesion. Primary sustained clinical improvement was a secondary outcome defined as a decrease in Rutherford classification of ≥1 categories compared with baseline without a repeat target lesion revascularization. Health-related quality of life and walking function were assessed. RESULTS A total of 775 patients were randomly assigned to treatment with DES (n=508) or commercially available BMSs (n=267). Baseline clinical, demographic, and lesion characteristics were similar between the study groups. Mean lesion length was 75.6±50.3 and 72.2±47.0 mm in the DES and BMS groups, respectively. The 12-month incidence of primary patency for DES treatment (83.2% [337 of 405]) was significantly greater than for BMS (74.3% [165 of 222]; P<0.01). Incidence of primary sustained clinical improvement was greater among patients treated with the DES than among those who received a BMS (83.0% versus 76.6%; P=0.045). The health-related quality of life dimensions of mobility and pain/discomfort improved for the majority of patients in both groups (for 66.4% and 53.6% of DES-treated and for 64.2% and 58.1% of BMS-treated patients, respectively) but did not differ significantly. At 12 months, no statistical difference was observed in all-cause mortality between patients treated with the DES or BMS (2.7% [13 of 474] versus 1.1% [3 of 263]; relative risk, 2.4 [95% CI, 0.69-8.36]; P=0.15). CONCLUSIONS By demonstrating superior 1-year primary patency, the results of the EMINENT randomized study support the benefit of using a polymer-based paclitaxel-eluting stent as a first-line stent-based intervention for patients with symptomatic peripheral artery disease attributable to femoropopliteal lesions.

Safety of paclitaxel-coated devices in the femoropopliteal arteries: A systematic review and meta-analysis. PLoS One 2022; 17:e0275888.

Abstract
Background Clinical benefit of paclitaxel-coated devices for patients with peripheral arterial disease has been confirmed in randomized controlled trials (RCTs). A meta-analysis published in 2018 identified late mortality risk over a long follow-up period due to use of paclitaxel-coated devices in the femoropopliteal arteries, which caused enormous controversy and debates globally. This study aims to further evaluate the safety of paclitaxel-coated devices by incorporating the most recently published data. Methods We searched for candidate studies in PubMed (MEDLINE), Scopus, EMBASE (Ovid) online databases, government web archives and international cardiovascular conferences. Safety endpoints of interest included all-cause mortality rates at one, two and five years and the risk ratio (RR) was used as the summary measure. The primary analysis was performed using random-effects models to account for potential clinical heterogeneity. Findings Thirty-nine RCTs including 9164 patients were identified. At one year, the random-effects model yielded a pooled RR of 1.06 (95% CI [0.87, 1.29]) indicating no difference in short-term all-cause deaths between the paclitaxel and control groups (crude mortality, 4.3%, 214/5025 versus 4.5%, 177/3965). Two-year mortality was reported in 26 RCTs with 382 deaths out of 3788 patients (10.1%) in the paclitaxel arm and 299 out of 2955 patients (10.1%) in the control arm and no association was found between increased risk of death and usage of paclitaxel-coated devices (RR 1.08, 95% CI [0.93, 1.25]). Eight RCTs recorded all-cause deaths up to five years and a pooled RR of 1.18 (95% CI [0.92, 1.51]) demonstrated no late mortality risk due to use of paclitaxel-coated devices (crude mortality, paclitaxel 18.2%, 247/1360 versus control 15.2%, 122/805). Conclusions We found no significant difference in either short- or long-term all-cause mortalities between patients receiving paclitaxel-coated and uncoated devices. Further research on the longer-term safety of paclitaxel usage (e.g., 8- or 10-year) is warranted. Registration PROSPERO, CRD42021246291.

Abstract
Background and Objectives: Indications for the endovascular treatment of femoropopliteal lesions have steadily increased over the past decade. Accordingly, the number of devices has also increased, but the choice of the best endovascular treatment remains to be defined. Many devices are now available for physicians. However, in order to obtain a high success rate, it is necessary to respect an algorithm whose choice of device is only one step in the treatment. Materials and Methods: The first step is, therefore, to define the approach according to the lesion to be treated. Anterograde approaches (femoral, radial, or humeral) are distinguished from retrograde approaches depending on the patient’s anatomy and surgical history. Secondarily, the lesion will be crossed intraluminally or subintimally using a catheter or an angioplasty balloon. The third step corresponds to the preparation of the artery, which is essential before the implantation of the device. It has a crucial role in reducing the rate of restenosis. Several tools are available and are chosen according to the lesion requiring treatment (stenosis, occlusion). Among them, we find the angioplasty balloon, the atherectomy probes, or intravascular lithotripsy. Finally, the last step corresponds to the choice of the device to be implanted. This is also based on the nature of the lesion, which is considered short, up to 15 cm and complex beyond that. The choice of device will be between bare stents, covered stents, drug-coated balloons, and drug-eluting stents. Currently, drug-eluting stents appear to be the treatment of choice for short lesions, and active devices seem to be the preferred treatment for more complex lesions, although there is a lack of data. Results: In case of failure to cross the lesion, the retrograde approach is a safe and effective alternative. Balloon angioplasty currently remains the reference method for the preparation of the artery, the aim of which is to ensure the intraoperative technical success of the treatment (residual stenosis < 30%), to limit the risk of dissection and, finally, to limit the occurrence of restenosis. Concerning the treatment, the drug-eluting devices seem to present the best results, whether for simple or complex lesions. Conclusions: Endovascular treatment for femoropopliteal lesions needs to be considered upstream of the intervention in order to anticipate the treatment and the choice of devices for each stage.

Abstract
Was ist neu?
Paclitaxel-beschichtete Ballons bei femoropoplitealen Läsionen Für die Behandlung femoropoplitealer Gefäßläsionen, bei Verschlusslängen unter 25 cm sowie bei längeren Verschlüssen (wenn kein Venenmaterial vorliegt und/oder das Operationsrisiko hoch ist), wird die endovaskuläre Therapie empfohlen. Um Restenosierungen und Reinterventionen zu vermeiden, wird dabei die Verwendung von medikamentenbeschichteten Ballons empfohlen. Durch die Weiterentwicklung des Ballondesigns kann die Effektivität noch gesteigert werden.
Paclitaxel-beschichtete Ballons bei infrapoplitealen Läsionen Im Stadium der kritischen Extremitäten-Ischämie wird bei infrapoplitealen Gefäßläsionen primär ebenfalls ein endovaskulärer Therapieansatz empfohlen. Aufgrund von inkonsistenten, teilweise widersprüchlichen Ergebnissen verschiedener klinischer Studien, kann der Vorteil medikamentenbeschichteter Ballons bei der Angioplastie infrapoplitealer Arterien bislang nicht ausreichend beurteilt werden.
Sicherheitsaspekt Paclitaxel-beschichteter Ballons Zahlreiche Real-World-Studien und Nachauswertungen prospektiver Studien konnten den in einer früheren Metaanalyse postulierten Zusammenhang einer höheren Mortalität nach Anwendung Paclitaxel-beschichteter Devices weder bestätigen noch einen möglichen Pathomechanismus oder eine Dosis-Wirkungs-Beziehung aufzeigen. Dennoch wurden die Empfehlungen des Bundesinstituts für Arzneimittel und Medizinprodukte (BfArM) zur sorgfältigen Nutzen-Risiko-Abwägung und Aufklärungspflicht noch nicht angepasst.
Sirolimus-beschichtete Ballons Mit dem Zytostatikum Sirolimus steht eine weitere antiproliferativ und zusätzlich antientzündlich wirkende Substanz zur Vermeidung von Restenosierungen bei femoropoplitealen und infrapoplitealen Läsionen zur Verfügung. Die therapeutische Breite von Sirolimus ist zwar größer als die von Paclitaxel, dennoch ist die Gewebeabsorption und -retention von Sirolimus deutlich schwieriger. Erste Ergebnisse aus kleineren Studien, die die Sicherheit und Effektivität Sirolimus-beschichteter Ballons untersuchten, sind vielversprechend, müssen allerdings noch in großen, prospektiven, randomisierten Studien bewiesen werden.

Abstract
Endovascular revascularization strategies have advanced tremendously over the years and are now often considered first line for treatment of peripheral arterial disease. Drug-eluting stents (DESs) have been developed as one of the tools to overcome the limitations of elastic recoil and neointimal hyperplasia observed with balloon angioplasty and bare metal stents. While these stents have been extremely successful in coronary revascularization, they have not translated as effectively to the peripheral arteries which differ in their unique mechanical environments and differences in vessel and lesion composition. DESs, through their embedded pharmaceutical agent, seek to inhibit vascular smooth muscle cell (VSMC) proliferation and migration. Paclitaxel, sirolimus, and its derivatives (-limus family) achieve VSMC inhibition through unique mechanisms. Several clinical trials have been performed to evaluate the use of DES in the femoropopliteal and infrapopliteal territory and have demonstrated overall decrease in revascularization rates and improved clinical outcomes.

Abstract
AIMS Cardiac resynchronization therapy (CRT) is an established treatment for heart failure. There is contradictory evidence whether defibrillator capability improves prognosis in patients receiving CRT. We compared the survival of patients undergoing de novo implantation of a CRT with defibrillator (CRT-D) option and CRT with pacemaker (CRT-P) in a large health claims database. METHODS AND RESULTS Using health claims data of a major German statutory health insurance, we analysed patients with de novo CRT implantation from 2014 to 2019 without indication for defibrillator implantation for secondary prevention of sudden cardiac death. We performed age-adjusted Cox proportional hazard regression and entropy balancing to calculate weights to control for baseline imbalances. The analysis comprised 847 CRT-P and 2722 CRT-D patients. Overall, 714 deaths were recorded during a median follow-up of 2.35 years. A higher cumulative incidence of all-cause death was observed in the initial unadjusted Kaplan-Meier time-to-event analysis [hazard ratio (HR): 1.63, 95% confidence interval (CI): 1.38-1.92]. After adjustment for age, HR was 1.13 (95% CI: 0.95-1.35) and after entropy balancing 0.99 (95% CI: 0.81-1.20). No survival differences were found in different age groups. The results were robust in sensitivity analyses. CONCLUSION In a large health claims database of CRT implantations performed in a contemporary setting, CRT-P treatment was not associated with inferior survival compared with CRT-D. Age differences accounted for the greatest part of the survival difference that was observed in the initial unadjusted analysis.

Abstract
OBJECTIVE To investigate mortality and causes of death associated with the use of paclitaxel-coated balloon (PCB) compared to plain balloon (PB) angioplasty in the treatment of femoropopliteal artery lesions in real-world clinical setting. METHODS This retrospective single-center study included patients who underwent percutaneous femoropopliteal artery angioplasty without stenting between years 2014 and 2020. Patients were stratified into PCB and PB groups according to the index procedure. Those who had undergone any prior or subsequent intervention using drug-eluting technology were excluded from the PB group. Long-term survival was estimated up to 5 years using the Kaplan-Meier method and risk factors for all-cause mortality were assessed in a multivariable analysis. Causes of death were retrieved from a national registry. RESULTS The study included 139 patients treated with PB and 190 with PCB. Patients treated with PCB had higher prevalence of chronic pulmonary disease (27% vs 17%; P=0.02) and were less often on anticoagulant therapy (34% vs 48%; P=0.01) compared to patients in the PB group. Those treated with PB were more likely to have chronic limb-threatening ischemia (CLTI; 82% vs 72%; P=0.04). Ipsilateral perioperative amputation rate was significantly higher in the PB group (7% vs 1%; P=0.01). There were no major differences in other 30-day outcomes between the groups and no differences in the rates of reinterventions and ipsilateral amputations during a mean follow-up time of 2.7±1.9 years. Survival at 1-year in the PCB group was 83±3% compared to 73±4% in the PB group (P=0.0001). The 5-year survival estimates were 56±5% and 37±5%, respectively. PCB use was independently associated with decreased risk of mortality (hazard ratio [HR], 0.70; 95% confidence interval [CI] 0.50-0.97). Independent risk factors for increased mortality were age (HR 1.04 per year; 95% CI 1.02-1.06), cardiac insufficiency (HR 1.60; 95% CI 1.12-2.27), chronic renal insufficiency (HR 2.04; 95% CI 1.47-2.85), anticoagulation therapy (HR 1.65, 95% CI 1.16-2.34) and CLTI (HR 2.85; 95% CI 1.51-5.39). In the PCB group, 63% of deaths were due to cardiovascular causes compared to 42% in the PB group (P<0.01). CONCLUSIONS The use of PCB is safe and there is no concern of increased mortality after the procedure based on the 5-year survival estimates.

Abstract
BACKGROUND Recent meta-analysis of randomized-controlled trials reported an increased risk of long-term mortality in patients treated with paclitaxel-coated devices (PCD) for femoropopliteal arteries (FP) lesions. However, real-life data on the subject is contradictory and data from CLTI patients is missing. The authors aim to evaluate the impact of PCD for the treatment of FP lesions on long-term mortality and amputation on a real-life cohort up to 5 years. METHODS All patients treated for FP lesions with endovascular devices from January 2013 to December 2016 were included, irrespective of clinical presentation. Primary endpoint is overall survival. Secondary endpoints are freedom-from major amputation and amputation-free survival. Survival estimates were obtained using Kaplan-Meier plots and a multivariable model was constructed to correct for relevant baseline differences. RESULTS From 2013 to 2016, 351 patients with FP lesions were treated, 250 with uncoated devices (nPCD) and 101 with PCD. Patients treated with nPCD were significantly older, more often female and with more severe degrees of ischemia. Median follow-up was 55(20-71) months. Overall survival and amputation-free survival were significantly higher in patients treated with PCD. Survival at one-year was 79% vs. 92%, at two-years 69% vs. 79% and at five-years 50% vs. 65% (P=.02). AFS was 43% vs. 57% at 5-years(P=.016). Freedom-from major amputation was similar between groups. After correction for relevant baseline differences on multivariable analysis, the survival advantage for patients treated with PCD was lost at 2 and 5 years. CONCLUSIONS Our results do not confirm the findings of increased mortality associated with PCD. However, no improvement in amputation rate was found. For the time, our institutional data does not support withholding PCD to reduce mortality but suggests that the benefit in preventing amputation is not significant.

Abstract
OBJECTIVE There have been concerns about the long term safety of paclitaxel coated devices in the lower limbs. A formal systematic review and meta-analysis of randomised controlled trials (RCTs) was performed to examine the long term risk of major amputation using paclitaxel coated balloons in peripheral arterial disease (PAD). METHOD This systematic review was registered with PROSPERO (ID 227761). A broad bibliographic search was performed for RCTs investigating paclitaxel coated balloons in the peripheral arteries (femoropopliteal and infrapopliteal) for treatment of intermittent claudication or critical limb ischaemia (CLI). The literature search was last updated on 20 February 2021 without any restrictions on publication language, date, or status. Major amputations were analysed with time to event methods employing one and two stage models. Sensitivity and subgroup analyses, combinatorial meta-analysis, and a multivariable dose response meta-analysis to examine presence of a biological gradient were also performed. RESULTS In all, 21 RCTs with 3 760 lower limbs were analysed (52% intermittent claudication and 48% CLI; median follow up two years). There were 87 major amputations of 2 216 limbs in the paclitaxel arms (4.0% crude risk) compared with 41 major amputations in 1 544 limbs in the control arms (2.7% crude risk). The risk of major amputation was significantly higher for paclitaxel coated balloons with a hazard ratio (HR) of 1.66 (95% CI 1.14 - 2.42; p = .008, one stage stratified Cox model). The prediction interval was 95% CI 1.10 - 2.46 (two stage model). The observed amputation risk was consistent for both femoropopliteal (p = .055) and infrapopliteal (p = .055) vessels. Number needed to harm was 35 for CLI. There was good evidence of a significant non-linear dose response relationship with accelerated risk per cumulative paclitaxel dose (chi square model p = .007). There was no evidence of publication bias (p = .80) and no significant statistical heterogeneity between studies (I2 = 0%, p = .77). Results were stable across sensitivity analyses (different models and subgroups based on anatomy and clinical indication and excluding unpublished trials). There were no influential single trials. Level of certainty in evidence was downrated from high to moderate because of sparse events in some studies. CONCLUSION There appears to be heightened risk of major amputation after use of paclitaxel coated balloons in the peripheral arteries. Further investigations are warranted urgently.

Abstract
Endovascular treatment of peripheral arterial disease has evolved and expanded rapidly over the last 20 years. New technologies have increased the diversity of devices available and have made it possible to approach even the most challenging and high-risk lesions using endovascular techniques. In this review, we examine the clinical evidence available for several categories of endovascular devices available to treat peripheral arterial disease, including intravascular lithotripsy, atherectomy, and drug-coated devices. The best application for some technologies, such as intravascular lithotripsy and atherectomies, have yet to be identified. In contrast, drug-coated devices have an established role in patients at high risk for long-term failure, but have been the subject of much controversy, given recent concerns about possible adverse effects of paclitaxel. Future investigation should further assess these technologies in patients with complex disease using updated staging systems and outcomes with direct clinical relevance, such as functional improvement, wound healing, and freedom from recurrent symptoms.

Abstract
OBJECTIVES This study sought to determine the safety and efficacy of paclitaxel (PTX) devices in the treatment of peripheral artery disease involving the femoropopliteal artery. BACKGROUND A meta-analysis of PTX devices for the treatment of femoropopliteal artery disease reported a mortality signal. METHODS This was a multicenter cohort study using an integrated clinical data surveillance system to conduct a prospective, propensity score-matched survival analysis of 2,456 patients in the Society for Vascular Surgery Vascular Quality Initiative from January 2017 to May 2020. The study compared PTX drug-coated balloon angioplasty versus percutaneous transluminal balloon angioplasty, PTX drug-eluting stents versus bare-metal stents, and any PTX device versus any non-PTX device. The primary outcome was 2-year survival. Secondary endpoints were successful ambulation and interventional success. RESULTS Treatment with any PTX device versus any non-PTX device was associated with increased 2-year survival (89.5% vs 86.7%; HR: 0.79; 95% CI: 0.72-0.87; P = 0.004), improved interventional success (81.6% vs 77.6%; HR: 0.82; 95% CI: 0.74-0.91; P < 0.001), and higher rates of independent ambulation at 1 year (86.0% vs 83.4%; HR: 0.85; 95% CI: 0.79-0.91; P = 0.008). Treatment with PTX drug-coated balloon angioplasty was associated with improved survival at 2 years (88.9% vs 85.7%; HR: 0.77; 95% CI: 0.70-0.86; P = 0.005), while PTX drug-eluting stent therapy was associated with similar survival compared with bare-metal stent therapy (91.3% vs 89.6%; HR: 0.84; 95% CI: 0.70-1.01; P = 0.36). CONCLUSIONS In this prospective, active surveillance of a national clinical registry, PTX-containing devices were associated with increased survival at 2 years and improved clinical outcomes at 1 year.

Characteristics of atherosclerosis in femoropopliteal artery and its clinical relevance. Atherosclerosis 2021; 335:31-40.

Abstract
Atherosclerosis is a systemic disease with different faces. Despite identical or similar pathogenetic mechanisms, atherosclerotic lesions and their clinical manifestations vary in different parts of the vascular system. Peripheral arterial disease (PAD) represents one of the most frequent clinical manifestations of atherosclerosis with predominant location in the superficial femoral artery (SFA). Morphological characteristics of atherosclerotic plaques in peripheral arteries differ from lesions in the coronary and carotid arteries. Plaques in SFA have more fibrotic components, less lipids and inflammatory cells, which makes them more stable and less prone to rupture. Factors that determine the different structure of plaques in SFA compared to coronary arteries include hemodynamic forces, vasa vasorum and calcification. Low shear stress in SFA in the adductor canal is one of the factors which determines frequent atherosclerotic lesions in this region. Lower lipid content and fewer inflammatory cells explain higher stability of SFA plaques. The specific structure of SFA plaques may require preventive and therapeutic measures, which to some extent differ from prevention of coronary atherosclerosis and may include inhibition of fibrotic proliferation in SFA plaques and calcification. Revascularization of PAD differs from procedures used in coronary arteries and requires specific technical expertise and devices.

Abstract
BACKGROUND Meta-analyses of randomised trials of paclitaxel-coated peripheral devices found an association with worse long-term survival. AIMS We aimed to assess long-term mortality in patients treated with drug-coated versus non-drug-coated devices who are insured by Medicare Advantage (MA), an alternative to traditional Medicare that represents >30% of the Medicare eligible population. We analysed data from an MA administrative claims data source that includes both inpatient and outpatient femoropopliteal artery revascularisation procedures. METHODS Patients treated with or without drug-coated devices for femoropopliteal artery revascularisation from 4/2015-12/2017 were studied using Optum's De-identified Clinformatics Datamart Database. Mortality was assessed up to December 2019 using Kaplan-Meier cumulative mortality curves and Cox proportional hazard models. Inverse probability of treatment weighting was used to adjust for differences between groups. RESULTS Of 16,796 patients revascularised, 4,427 (26.4%) were treated with drug-coated devices: 3,600 (81.3%) balloons and 827 (18.7%) stents. The median follow-up was 2.66 years (IQR 2.02-3.52). Treatment with drug-coated devices was associated with similar long-term mortality to non-drug-coated devices (adjusted HR 1.03, 95% CI: 0.96-1.10; p=0.39). Results were comparable for patients treated with balloons alone (adjusted HR 1.00, 95% CI: 0.92-1.08; p=0.96) or stents (adjusted HR 1.02, 95% CI: 0.88-1.18; p=0.78). These findings did not differ based on treatment setting, disease severity, age, sex or comorbidity burden (interaction p>0.05 for all). CONCLUSIONS In this large cohort, there was no evidence of increased long-term mortality following treatment with drug-coated devices.

Mortality is not associated with paclitaxel-coated devices usage in peripheral arterial disease of lower extremities. Sci Rep 2021; 11:18214. [PMID: 34521940 PMCID: PMC8440584 DOI: 10.1038/s41598-021-97675-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 08/26/2021] [Indexed: 12/24/2022] Open
Abstract
A recent meta-analysis addressed increased risk of death following revascularization with paclitaxel-coated devices in femopopliteal artery. We evaluated differences in all-cause mortality and amputation free survival between peripheral arterial disease (PAD) patients who were treated with paclitaxel-coated devices and non-paclitaxel-coated devices. This was retrospective population-based cohort study from the National Health Insurance Service claims in South Korea from 2015 to 2019. Multivariate Cox regression analyses after propensity score matching were applied to identify all-cause mortality and amputation-free survival. After propensity score matching, there were 6090 patients per group. The median follow-up days was 580 days (interquartile range [IQR] 240–991 days) and 433 days (IQR 175–757 days) for the non-paclitaxel-coated device group and paclitaxel-coated device group, respectively. Multivariate analysis adjusted for age, sex, diabetes, hypertension, warfarin, and new oral anticoagulants showed that the mortality rate associated with paclitaxel-coated devices was not significantly higher than non-paclitaxel-coated devices (hazard ratio [HR] 0.992; 95% CI 0.91–1.08). The rate of amputation events was higher in patients with paclitaxel-coated devices than those with non-paclitaxel-coated devices (HR 1.614; 95% CI 1.46–1.78). In this analysis, the mortality rate in patients with PAD was not associated with the use of paclitaxel-coated devices, despite a higher amputation rate.

Mortality after Use of Paclitaxel-Coated Balloons Correlates with Total Cumulative Dosage of Paclitaxel in Real-World Analysis. J Clin Med 2021; 10:jcm10163747. [PMID: 34442040 PMCID: PMC8396966 DOI: 10.3390/jcm10163747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 08/14/2021] [Accepted: 08/17/2021] [Indexed: 11/16/2022] Open
Abstract
This study used independent, real-world, patient-level data to examine whether the dosage or frequency of paclitaxel exposure correlated with mortality during follow up. We conducted a retrospective analysis of patients treated with a drug-coated balloon (DCB) for an atherosclerotic femoropopliteal lesion from February 2013 to December 2018, excluding patients with non-atherosclerotic lesions or restenosis after DCB treatment in another hospital. We investigated the causes of death, comorbidities (including cancer status), and the initial and total cumulative dosages and frequency of paclitaxel use. To determine whether the dosage or frequency of paclitaxel exposure affected mortality during follow up, we analyzed the risk factors for all-cause death by conducting a time-dependent Cox regression analysis that considered demographics, comorbidities, lesion and procedural characteristics, and paclitaxel exposure data (dosage and frequency). Our analysis examined 225 patients (mean age 71 ± 9 years, range 38–93 years, male 81%). During a mean follow-up duration of 35 months (range 1–89 months), 56 patients (24.9%) died from cardiac disorders (16%, including acute myocardial infarction, heart failure, or sudden cardiac arrest), malignancy (14.3%), respiratory failure with pneumonia (12.5%), septic shock (12.5%), or another cause. Univariable and multivariable Cox regression analyses identified age (hazard ratio, HR, 1.057; 95% confidence interval, CI, 1019–1096; p = 0.0032), critical limb ischemia (CLI) (HR, 4135; 95% CI, 2171–7876; p < 0.0001), and the total dosage of paclitaxel (mg) (HR, 1.040; 95% CI, 1006–1074; p = 0.0210) as predictors of mortality during follow up. The subgroup analysis found that the total dosage of paclitaxel (mg) was also a predictor of mortality during follow up in the CLI group (HR, 1.046; 95% CI, 1007–1087, p = 0.0198). The estimated cut-off value of total cumulative paclitaxel dosage for predicting mortality was 12 mg as evaluated by minimum p value approach. This patient-level analysis identified the total cumulative dosage of paclitaxel as a predictor of mortality after the use of paclitaxel-coated balloons. Our results provide limited information about the potential dose–response relationship underlying paclitaxel-associated mortality concerns.

Abstract
Background: Previous observational studies reported a wide variation and possible room for improvement in the treatment of patients suffering from symptomatic peripheral artery disease (PAD). Yet, systematic assessment of everyday clinical practice is lacking. A General Data Protection Regulation (GDPR) compliant registry was developed and used to collect comprehensive data on clinical treatment and outcomes regarding PAD in Germany. Here, we report baseline characteristics of patients prospectively enrolled until the end of 2020. Methods: The GermanVasc registry study is a prospective longitudinal multicentre cohort study. Between 1st May 2018 and 31st December 2020, invasive endovascular, open-surgical, and hybrid revascularisations of patients suffering from chronic symptomatic PAD were prospectively included after explicit informed consent (NCT03098290). For ensuring high quality of the data, we performed comprehensive risk-based and random-sample external and internal validation. Results: In total, 5608 patients from 31 study centres were included (34% females, median 69 years). On-site monitoring visits were performed at least once in all centres. The proportion of chronic limb-threatening ischaemia was 30% and 13% were emergent admissions. 55% exhibited a previous revascularisation. Endovascular techniques made 69% among all documented invasive procedures (n=6449). Thirty-five percent were classified as patients with severe systemic disease, and 3% exhibited a constant threat to life according to the American Society of Anaesthesiologists classification. The risk profile comprised of 75% former or current smokers, 36% diabetes mellitus, and in 30% a current ischemic heart disease was present. At discharge, 93% of the patients received antiplatelets and 77% received statins. Conclusions: The GermanVasc registry study provides insights into real-world practice of treatment and outcomes of 5,608 patients with symptomatic PAD in Germany. The cohort covers a broader range of disease severity and types of interventions than usually found in trials. In future studies, comparative outcomes will be analysed in more detail.

Abstract
BACKGROUND Randomized controlled trials have reported excess mortality in patients treated with paclitaxel-coated devices versus uncoated devices, while observational studies have reported the opposite. This study aims to determine the underlying factors and cohort differences that may explain these opposite results, with specific focus on sex differences in treatment and outcomes. METHODS Multicenter health insurance claims data from a large insurance fund, BARMER, were studied. A homogeneous sample of patients with an index of endovascular revascularization for symptomatic peripheral arterial occlusive disease between 2013 and 2017 was included. Adjusted logistic regression and Cox regression models were used to determine the factors predicting allocation to paclitaxel-coated devices and sex-specific 5-year all-cause mortality, respectively. RESULTS In total, 13,204 patients (54% females, mean age 74 ± 11 years) were followed for a median of 3.5 years. Females were older (77 vs. 71 years), and had less frequent coronary artery disease (23% vs. 33%), dyslipidemia (44% vs. 50%), and diabetes (29% vs. 41%), as well as being less likely to have a history of smoking (10% vs. 15%) compared with males. Mortality differences were mostly attributable to the female subgroup who were revascularized above the knee (hazard ratio, HR 0.78, 95% CI: 0.64-0.95), while no statistically significant differences were observed in males. CONCLUSIONS This study found that females treated above the knee benefited from paclitaxel-coated devices, while no differences were found in males. Ongoing and future registries and trials should take sex disparities into account.

Abstract
Purpose Drug-coated devices have been widely accepted as one of the most promising therapies for femoropopliteal artery revascularization. A recent meta-analysis showed increased mortality in patients treated with drug-coated devices. We sought to examine the association between mortality and drug-coated devices after the treatment of the femoropopliteal artery based on the Korea national administrative claims data. Methods In the National Health Insurance Service database from August 2015 to December 2017, we identified patients with femoropopliteal artery revascularization using percutaneous transluminal angioplasty (PTA), bare metal stents (BMS), drug-coated balloon (DCB), or drug-eluting stents (DES). Kaplan-Meier methods were used to estimate the survival among devices, and log-rank tests were used to evaluate differences between groups. Adjusted hazard ratios (aHRs) were computed using the inverse probability of treatment weightings (IPTW). Results There were 1,724 patients (mean age, 70.9 ± period was 552 days (interquartile range, 404-688 days). There was a difference in IPTW-adjusted mortality risk among device types (26.3% in PTA, 22.1% in BMS, 17.7% in DCB, and 17.8% in DES; P = 0.004). IPTW-adjusted Cox nproportional hazard analysis showed that drug-coated devices were associated with decreased all-cause mortality risk (aHR, 0.70; 95% confidence interval, 0.58-0.86). Conclusion Our real-world analysis showed that there was no evidence of increased all-cause mortality after femoropopliteal artery revascularization with drug-coated devices compared with non-drug-coated devices.

Abstract
OBJECTIVES Recent controversies on the use of drug coated/eluting devices in the arteries of the lower extremities renewed the focus on the evaluation of more conventional techniques. The results of the stenting of short and/or intermediate femoro-popliteal lesions are well known, but little data relate to the endovascular treatment of long femoro-popliteal lesions with contiguous bare metal stents (ETLFBS). The objective of this study was to report our results of ETLFBS. MATERIAL AND METHODS Between January 2014 and December 2017, 1233 patients had an infrainguinal angioplasty in our center. The files of patients treated for femoropopliteal lesions longer than 250 mm using extensive stenting with contiguous bare metal stents were reviewed and analyzed. The primary outcome was the 12-month primary patency, defined by the absence of restenosis (≥50%) and/or reintervention on the target lesion. Continuous data were expressed as mean and standard deviation. Survival analysis was carried out according to Kaplan-Meier. RESULTS Overall, 64 patients aged 80 ± 11 years were included, with 49 (76.6%) presenting with critical limb ischemia. Lesions were classified as TASC D in 54.7% of the cases. The length of the lesions was 295 ± 64 mm and 3 ± 1 stents were implanted. The 30-day mortality was null but two patients (3.1%) presented nonvascular major complications. With a follow-up of 27 ± 17 months, 22 patients (34.3%) died including three of vascular causes. The healing of the trophic disorder was obtained in 77.5% of the cases. The rate of amputation was 10.9%. The 6-, 12-, and 24-month primary patency rates were 79.7%, 66.6%, and 60.9%, respectively. The 6-, 12-, and 24-month rates of freedom from target lesion revascularization were 96.3%, 73.9%, and 71.9%, respectively. The 6-, 12-, and 24-month survival rates were 90.3%, 83.6%, and 65.6%, respectively. CONCLUSIONS The 12-month primary patency rate of ETLFBS is acceptable. This strategy constitutes an acceptable alternative in patients presenting with critical limb ischemia and a limited life expectancy.
