RESUMO
BACKGROUND: First-generation drug-coated balloons (DCBs) have significantly reduced the rate of restenosis compared with balloon angioplasty alone; however, high rates of bailout stenting and dissections persist. The Chocolate Touch DCB is a nitinol constrained balloon designed to reduce acute vessel trauma and inhibit neointima formation and restenosis. METHODS: Patients with claudication or ischemic rest pain (Rutherford class 2-4) and superficial femoral or popliteal disease (≥70% stenosis) were randomized 1:1 to Chocolate Touch or Lutonix DCB at 34 sites in the United States, Europe, and New Zealand. The primary efficacy end point was DCB success, defined as primary patency at 12 months (peak systolic velocity ratio <2.4 by duplex ultrasound without clinically driven target lesion revascularization in the absence of clinically driven bailout stenting). The primary safety end point was freedom from major adverse events at 12 months, a composite of target limb-related death, major amputation, or reintervention. Both primary end points were tested for noninferiority, and if met, sequential superiority testing for efficacy followed by safety was prespecified. An independent clinical events committee, and angiographic and duplex ultrasound core laboratories blinded to treatment allocation reviewed all end points. RESULTS: A total of 313 patients were randomized to Chocolate Touch (n=152) versus Lutonix DCB (n=161). Follow-up at 1 year was available in 94% of patients. The mean age was 69.4±9.5 years, the average lesion length was 78.1±46.9 mm, and 46.2% had moderate-to-severe calcification. The primary efficacy rates of DCB success at 12 months was 78.8% (108/137) with Chocolate Touch and 67.7% (88/130) with Lutonix DCB (difference, 11.1% [95% CI, 0.6-21.7]), meeting noninferiority (Pnoninferiority<0.0001) and sequential superiority (Psuperiority=0.04). The primary safety event rate was 88.9% (128/144) with Chocolate Touch and 84.6% (126/149) with Lutonix DCB (Pnoninferiority<0.001; Psuperiority=0.27). CONCLUSIONS: In this prospective, multicenter, randomized trial, the second-generation Chocolate Touch DCB met both noninferiority end points for efficacy and safety and was more effective than Lutonix DCB at 12 months for the treatment of femoropopliteal disease.

The RANGER II SFA objective was to evaluate the safety and effectiveness of the Ranger Drug-Coated Balloon (DCB) for treating superficial femoral artery and/or proximal popliteal artery lesions; the purpose of this cohort analysis is to assess the results among Japanese study participants. Patients eligible for RANGER II SFA had symptomatic lower limb ischemia (Rutherford classification 2-4) and were randomly assigned (3:1) to treatment with the Ranger DCB or standard percutaneous transluminal angioplasty (PTA). At 12 months, assessments included freedom from major adverse events (i.e., target lesion revascularization, major amputations, or death within 1 month of the index procedure) and core laboratory-assessed primary patency. Japanese patients (n = 102) comprised 27.1% of the overall study sample. Mean lesion lengths were 79.5 ± 44.0 mm and 84.0 ± 56.8 mm among Japanese patients treated with Ranger DCB (n = 77) or PTA (n = 25), respectively. All major adverse events were clinically driven TLRs (6.6% [5/76] for Ranger DCB and 16.0% [4/25] for PTA; p = 0.2194). Kaplan-Meier estimates of primary patency were 89.3% and 72.0%, respectively, at 12 months (log-rank p = 0.2134). Japanese patients treated with Ranger DCB maintained a high patency rate through 12 months and a low re-intervention rate.Trial registration clinicaltrials.gov identifier: NCT03064126.

The demand for endovascular therapy is increasing in an aging society, but the problem of restenosis in the chronic phase has not been resolved in femoropopliteal occlusive disease. Few studies have compared drug-coated balloon (DCB) and scaffold devices in chronic total occlusion (CTO) of the superficial femoral artery (SFA). This study aimed to compare DCBs with scaffold in patients with CTO of the SFA. This was a single-center, retrospective study. From June 2018 to December 2019, we compared 31 patients and 33 limbs treated with DCBs and 44 patients and 45 limbs treated with a stent or stent-graft (scaffold) for SFA CTO. The primary endpoint was 12-month primary patency. The secondary endpoints were 12-month freedom from clinically driven target lesion revascularization (CD-TLR) and 12-month freedom from re-occlusion. The DCBs were performed using an intravascular ultrasound (IVUS)-guided approach or a non-loop wire technique. Baseline characteristics were similar between the groups. An intraluminal approach was performed to use all DCBs. The bailout stent rate was 0% in the DCB group. Kaplan-Meier analysis showed that rates of 12-month primary patency tended to be higher in the DCB than in the scaffold group (92.7 vs. 76.6%, p = 0.073) and that freedom from CD-TLR also did not differ significantly between the two groups (96.8 vs. 86.3%, p = 0.17). Kaplan-Meier analysis also showed that the 12-month freedom from re-occlusion rate was significantly less in the Scaffold than in the DCB group (96.8 vs. 79.3%, p = 0.045). Therefore, we concluded that in treatment for CTO of the SFA, a DCB with intraluminal angioplasty without bailout stenting was less re-occlusion compared with scaffold.

OBJECTIVES: Restenosis after stenting for superficial femoral artery atherosclerotic disease remains a significant clinical problem, especially for long-segment lesions. We assessed predictors of in-stent restenosis in patients with long-segment superficial femoral artery disease and hypothesized that pre-procedural ultrasound assessment would predict in-stent restenosis. METHODS: This single-center study retrospectively analyzed 283 limbs in 243 patients who treated with superficial femoral artery nitinol stent placement for long-segment (≥15 cm) lesions between 2015 and 2018. Color duplex ultrasound was performed pre-procedure and post-procedure at 3, 6, 12, 24, and 36 months. The endpoint was ≥50% in-stent restenosis in the superficial femoral artery. Primary patency rates were analyzed with Kaplan-Meier survival analysis and compared using the log-rank test. A multivariable Cox proportional hazards model was used to evaluate the risk factors for in-stent restenosis. RESULTS: The median length of lesions was 25.8 ± 8.1 cm. The cumulative freedom from ≥50% in-stent restenosis at 3, 6, 12, 24, and 36 months was 95.3%, 78.3%, 56.0%, 30.6%, and 15.9%, respectively. Univariate and multivariate Cox regression analysis showed that cumulative lesion length ≥ 25 cm (hazard ratio 1.681; p = 0.003), calcified plaque (hazard ratio 1.549, p = 0.006), poor runoff scores >10 (hazard ratio 1.870, p = 0.003), and chronic renal failure (hazard ratio 2.075, p = 0.009) were independent risk factors for in-stent restenosis. The agreement rate between ultrasound and angiography was 92.6% for cumulative lesion length (κ 0.851) and 91.9% for runoff score (κ 0.872). CONCLUSIONS: The results indicate that pre-procedural color duplex ultrasound evaluation is helpful for the selection of appropriate candidates for superficial femoral artery stent placement. Cumulative lesion length ≥25 cm, plaque calcification, poor distal runoff, and chronic renal failure independently predicted in-stent restenosis.

OBJECTIVE: Covered stents (CS) to treat superficial femoral artery (SFA) occlusive disease have become more common. However, concerns about patients presenting with acute limb ischemia (ALI) after failure due to coverage of important collaterals have been raised. Herein, we determine if CS are associated with ALI after failure. METHODS: Vascular Quality Initiative peripheral vascular intervention and infrainguinal bypass datasets were queried from 2010 to 2020 for patients who underwent SFA stenting with a bare metal stent (BMS) or CS and who also had a subsequent ipsilateral SFA endovascular reintervention or bypass recorded in the Vascular Quality Initiative. The initial SFA stenting procedure will be referred to as the index procedure and the subsequent procedure will be referred to as the reintervention. Patients with aneurysmal pathology, prior infrainguinal bypass, and ALI at the index procedure were excluded. Patients with pre-index inflow/outflow procedures were not excluded. The primary outcome was ALI at reintervention. Other outcomes included higher degree of ischemia (claudication vs rest pain vs tissue loss vs ALI) and reoperative factors. Predictors of the primary outcome were determined with multivariable logistic regression. The index treatment length and pre-index ankle-brachial index were forced into the model. RESULTS: There were 3721 patients: 3338 with index BMS, 383 with index CS. The mean patients age was 66.3 ± 11.0 years and 59.2% were male. Baseline covariates were similar between the groups; during the index procedure, more patients with BMS underwent plain balloon angioplasty (68.7% vs 62.1%; P = .001) and had shorter total index treatment length (median, 15.0 cm [interquartile range, 10.0-25.0 cm] vs 20.0 cm [interquartile range, 12.0-30.0 cm]; P < .001). At reintervention, ALI was the presenting symptom for 12.0% of the CS cohort vs 6.3% of the BMS cohort (P < .001). More patients with an index CS underwent major amputation at the time of reintervention (2.6% vs 1.0%; P = .006). Reinterventions for the patients with a CS more often used bypass, pharmacologic thrombolysis, and mechanical thrombolysis. CS at the index procedure was a predictor of ALI at reintervention (odds ratio, 1.87; 95% confidence interval, 1.31-2.65; P = .001) while controlling for age, time difference between procedures, body mass index, chronic obstructive pulmonary disorder, preoperative anticoagulation and antiplatelet, prior carotid intervention and major amputation, index procedure fluoroscopy time and treatment length, and pre-index ankle-brachial index. CONCLUSIONS: In patients undergoing reintervention for failed SFA stents, CS are more likely to present with ALI than those with failed SFA BMS.

OBJECTIVE: We assessed the long-term safety and efficacy of endovascular stent grafting to treat long, complex lesions in the superficial femoral artery (SFA). METHODS: The present prospective, multicenter study at 15 Japanese hospitals assessed heparin-bonded stent grafts used to treat long SFA lesions in patients with symptomatic peripheral arterial disease. The inclusion criteria were Rutherford category 2 to 5 symptoms (grade 5 without active infection), an ankle brachial index of ≤0.9, and SFA lesions ≥10 cm long with ≥50% stenosis. The key efficacy and safety outcomes were primary-assisted patency and adverse events through 24 months, respectively. The secondary outcomes included primary patency, secondary patency, freedom from target lesion revascularization (fTLR), and Vascular Quality of Life questionnaire score. RESULTS: Of the 103 patients (mean age, 74.2 ± 7.0 years; 82.5% male), 100 (97.1%) had intermittent claudication. The average lesion length was 21.8 ± 5.8 cm; 87 lesions (84.5%) were TASC (Trans-Atlantic Inter-Society Consensus Document on Management of Peripheral Arterial Disease) C or D (65.7% chronic total occlusions). Of the 103 patients, 92 and 61 were evaluable through 24 and 60 months, respectively. At 24 months, the Kaplan-Meier-estimated primary-assisted patency, primary patency, and secondary patency rate was 85.7% (95% confidence interval [CI], 76.3%-91.5%), 78.8% (95% CI, 68.8%-85.9%), and 92.0% (95% CI, 82.4%-96.5%), respectively. The mean ankle brachial index was 0.64 ± 0.12 at baseline and 0.94 ± 0.19 at 24 months (P < .0001). At 24 and 60 months, the fTLR was 87.2% (95% CI, 78.9%-92.3%) and 79.1% (95% CI, 67.9%-86.8%), respectively. No device- or procedure-related life- or limb-threatening critical events or acute limb ischemia cases were observed through 5 years. No stent fractures were detected on the annually scheduled follow-up radiographs. The vascular quality of life questionnaire and walking impairment questionnaire scores were significantly increased at 1 through 24 months compared with the baseline scores (P < .0001 for both). One patient had required conversion to open bypass during the 5-year follow-up period. CONCLUSIONS: Stent grafting of long and complex SFA lesions in patients with claudication is safe and effective through long-term follow-up, with 79.1% fTLR and no leg amputation, acute limb ischemia, or stent fractures through 5 years.

PURPOSE: To investigate lumen loss (LL) at 1 year after bare nitinol stent (BNS) implantation for de novo superficial femoral artery (SFA) lesions. MATERIALS AND METHODS: The subjects were 701 consecutive patients (mean age 74±9 years; 492 men) with 817 de novo SFA lesions treated with BNS implantation between January 2004 and September 2015. The mean lesion length was 141±88 mm and the mean vessel diameter was 5.4±0.9 mm. The endpoint was LL at 1 year after BNS implantation. Secondary outcomes were restenosis and target lesion revascularization (TLR) estimated using the Kaplan-Meier method; estimates are reported with the 95% confidence interval (CI). LL was defined as the minimum lumen diameter immediately after BNS implantation minus that at 1 year measured by angiographic quantitative vessel analysis. The distribution of LL in the overall population was estimated using an accelerated failure time model. RESULTS: Mean LL at 1 year was estimated to be 1.74±1.28 mm (95% CI 1.63 to 1.84). Current smoking was positively associated with LL (p=0.015), whereas lack of cilostazol use was correlated with an increase in LL (p=0.001). Reference vessel diameter and lesion length did not have any significant association with LL at 1 year. The 1-year cumulative estimate of restenosis was 25% (95% CI 22% to 28%); the corresponding value for TLR was 18% (95% CI 15% to 21%). CONCLUSION: Mean LL progressed by at least 1.6 mm up to 1 year after BNS implantation. The risk factors for increased LL were current smoker and lack of cilostazol use.

BACKGROUND: Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR). This study aimed to investigate the impact of COF of oversizing SENS on ISR of SFA. METHODS: In patients with implanted SENS in SFA, intimal hyperplasia especially between proximal segment and distal segment was evaluated by quantitative angiography, and the impact of COF on mid-term angiographic outcomes was investigated. In addition, porcine model with implanted SENS was used to evaluate the impact of COF on angiographic and histopathologic outcomes at 1 month. Excised stented arteries were evaluated by histopathologic analysis. RESULTS: We analyzed 65 SENS in 61 patients with follow-up angiography at 6 months to 1 year. The baseline diameter was 6.8 ± 0.71 mm and length were 97.0 ± 33.8 mm for the SENS. The ratio of the diameter of the stent to the reference vessel was 1.3 ± 0.24 at the proximal portion and 1.53 ± 0.27 at the distal portion (P < 0.001). In the long SFA stent, stent-to-vessel ratio was significantly higher in the distal stent than in the proximal stent (1.3 ± 0.2 vs. 1.55 ± 0.25, P = 0.001). ISR incidence was higher at the distal stent (37.3% vs 52.6%, P = 0.029). All 11 pigs survived for 4 weeks after SENS implantation. The vessel diameter was 4.04 ± 0.40 mm (control group) vs 4.45 ± 0.63 mm (oversized group), and the implanted stent diameter was 5.27 ± 0.46 mm vs. 7.18 ± 0.4 mm (P = 0.001). The stent-to-vessel diameter ratio was 1.31 ± 0.12 versus 1.63 ± 0.20 (P < 0.001). After 4 weeks, restenosis % was 29.5 ± 12.9% versus 46.8 ± 21.5% (P = 0.016). The neointimal area was 5.37 ± 1.15 mm2 vs. 8.53 ± 5.18 mm2 (P = 0.05). The restenosis % was 39.34 ± 8.53% versus 63.97 ± 17.1% (P = 0.001). CONCLUSIONS: COF is an important cause of restenosis in the distal portion of the SFA stent. Optimal sizing of the SFA stent is important to reduce the incidence of restenosis. Therefore, COF was an important factor of restenosis following distal SFA stenting.

Drug-coated balloon (DCB) angioplasty for femoropopliteal (FP) lesions has been available in Japan since 2018. In daily practice, we encountered cases of the slow-flow phenomenon after DCB angioplasty. However, no data regarding the slow-flow phenomenon after DCB angioplasty for FP lesions are available. This study aimed to investigate the frequency, predictors, and effect of the slow-flow phenomenon following DCB angioplasty for FP lesions. This single-center, retrospective, observational study analyzed 88 FP lesions treated by DCB angioplasty between April 2018 and July 2019. Patients were divided into the slow-flow group (n = 7) and non-slow-flow group (n = 81) and were analyzed. The primary endpoint was primary patency at 6 months. The slow-flow phenomenon was observed in seven cases (8.0%). The slow-flow group had higher incidence rates of critical limb ischemia (CLI) (71% vs. 25%, p < 0.01), chronic total occlusion (CTO) lesions (86% vs. 26%, p < 0.01), and poor tibial vessel runoff (86% vs. 33%, p < 0.01) and had a longer DCB length (237 ± 56 mm vs. 159 ± 97 mm, p = 0.03) than the non-slow-flow group. The primary patency rate at 6 months was 71% in the slow-flow group and 91% in the non-slow-flow group (p = 0.09). The rate of freedom from target lesion revascularization at 6 months was 71% in the slow-flow group and 97% in the non-slow-flow group (p < 0.01). The amputation-free survival rate at 6 months was 71% and 95% (p = 0.02), whereas the survival rate at 6 months was 71% and 95% (p = 0.02). The incidence rate of the slow-flow phenomenon after DCB angioplasty for FP lesions was 8.0%. CLI, a CTO lesion, poor tibial vessel runoff, and total DCB length were associated with the slow-flow phenomenon. Our results indicate that the slow-flow phenomenon is associated with poor short-term clinical outcomes.

OBJECTIVE: To examine the efficacy and durability of an interwoven self-expanding nitinol stent for the treatment of superficial femoral and popliteal arteries. METHOD: Consecutive patients with severely diseased superficial femoral and popliteal arteries who received SUPERA® stents were retrospectively identified.The patients were followed for 12 months by Doppler ultrasound examinations, stent roentgenograms, and estimation of Rutherford-Becker class and ankle-brachial index. RESULTS: From July 2012 to May 2014, 42 limbs in 36 patients (mean age, 61.5 ± 7.5 years; 75% male) were treated with angioplasty and primary stenting. Total occlusions were present in 14 limbs, and 63.8% had either moderate or severe calcification. The mean (±SD) lesion length was 105 mm (±28). Primary patency was 91.4% at 6 months and 85.7% at 12 months. The ankle brachial index increased from 0.57 ± 0.19 preoperative to 0.91 ± 0.12 postoperative. There was no procedural or device-related morbidity or mortality after revascularization and only one major amputation was observed on follow-up. CONCLUSIONS: Our experience shows that, Supera stents are safe and effective in our cohort of patients, with acceptable patency rates. There were no stent fractures so far even with stenting of the femoropopliteal segments. Stent design provides a viable option for high-grade obstructive disease in the femoropopliteal artery.

BACKGROUND: Edge stenoses are the predominant limitation of self-expanding covered stent treatment of superficial femoral artery (SFA) occlusive disease, necessitating reinterventions. Angioplasty of an edge stenosis is associated with a high recurrence rate. Drug-coated balloon (DCB) treatment of edge stenoses might improve outcomes by decreasing the incidence of restenosis. PURPOSE: The aim of this study was to evaluate the outcomes of using a DCB for the treatment of edge stenoses after self-expanding covered stent placement for SFA occlusive disease. METHOD: We performed a retrospective analysis of patients treated with a DCB for edge stenoses after self-expanding covered stent placement. The primary endpoint was primary patency at one year. The secondary endpoints included procedure-related complications, secondary patency, and freedom from target lesion revascularization (TLR). RESULTS: A total of 21 patients with 28 edge stenoses were included. The time from primary treatment to treatment of the edge stenosis was 19 months (interquartile range (IQR) 8; 52 months). Primary patency and assisted primary patency at one year were 66.7% with a secondary patency of 90.9%. Freedom from TLR was 86.1%, and freedom from clinically driven TLR was 89.4%. Four patients presented with a hemodynamically significant restenosis, and three of those patients had an occlusion. Median time to failure was six months (IQR 3.5; 7.0 months), and median time to occlusion was four months (IQR 3.0; 6.0 months). CONCLUSION: The treatment of edge stenoses using a DCB is associated with a safe one-year outcome; however, this has to be confirmed in larger prospective studies. The continuous surveillance of patients is indicated.

AIMS: Drug-coated balloons (DCBs) for femoropopliteal interventions have not been tested against each other. We aimed to directly compare efficacy and safety of a high-dose (In.Pact™) vs. low-dose (Ranger™) DCB with nominal paclitaxel densities of 3.5 vs. 2.0 µg/mm2. METHODS AND RESULTS: Within a prospective, multicentre, non-inferiority, clinical trial 414 patients with symptomatic femoropopliteal lesions (Rutherford classification 2-4) were randomly assigned in a 1:1 ratio to endovascular treatment with either high- or low-dose DCB after stratification for lesion length. Primary efficacy and safety endpoints comprised primary patency and freedom from major adverse events (i.e. device and procedure-related deaths through 1 month, major amputations, and clinically driven target lesion revascularization through 12 months). We set a non-inferiority margin of -10% at 12 months. Total occlusions were observed frequently (>40%) and provisional stenting was performed in every fourth intervention. Non-inferiority was determined for both primary efficacy and safety endpoints at 12 months. Primary patency was 81.5% in the high-dose and 83.0% in low-dose DCB group {difference: 1.5% [lower bound of the 90% two-sided confidence interval (CI) -5.2%]; Pnon-inferiority < 0.01}. Freedom from major adverse events was determined in 92.6% in high-dose and in 91.0% in low-dose DCB group [difference -1.6% (lower bound of the 90% two-sided CI -6.5%); Pnon-inferiority < 0.01]. Overall death rate was low (2.0%) and no major amputation occurred. CONCLUSION: Two DCBs with different coating characteristics exhibited comparable results with excellent effectiveness and safety through 12 months for femoropopliteal interventions including a wide range of lesion lengths. CLINICAL TRIAL REGISTRATION: The trial is registered with ClinicalTrials.gov (NCT02701543).

Background: To evaluate the safety and effectiveness of preparing instent femoropopliteal lesion with photoablative laser atherectomy or plain balloon angioplasty (POBA) prior to drug-coated balloon (DCB) angioplasty. Patients and methods: The prospective, multicenter, randomized study enrolled patients with Rutherford-Becker-class (RBC) 1 to 5 and instent lesions located in superficial femoral artery and/or popliteal artery above the knee joint. Primary endpoint was target lesion percent stenosis at 1 year as determined by the angiographic core-laboratory. Secondary endpoints included procedural success, major adverse event rate, clinical improvement and improvement in ankle-brachial index (ABI), clinically-driven target lesion revascularization (CD-TLR), and primary patency rate at until 2-year follow-up. Results: The study was terminated prior to the enrollment goal due to slow enrollment. Thirty patients were included in the laser plus DCB cohort and 31 patients in the control cohort. Primary endpoint was not significantly different (p=0.331). Procedural success was 83.3% and 87.1% for the laser plus DCB and the control cohort, respectively. Serious adverse events at 30 days and 1-year were not statistically different between the two cohorts. For the ABI, significant improvements were present at discharge as well as at the follow-up visits. This was also evident for the RBC at the follow-up visits. One- and two-year freedom from CD-TLR was 86.7% vs. 87.1%, and 63.6% vs. 72%, respectively. Duplex derived primary patency was 90% at 6-months, 65.5% at one year and 56.5% at two year for the laser cohort and 90.3%, 75.9% and 53.8% for the control cohort. Conclusions: Safety of instent photoablative laser atherectomy followed by DCB angioplasty is confirmed by this study. Due to the small sample size, no benefit over POBA as vessel preparation could be shown.

OBJECTIVE: The Tack Endovascular System (Intact Vascular, Wayne, Pa) combines low-metallic content with focal delivery to seal areas of dissection associated with balloon angioplasty. The device system is designed to treat vascular dissections in the superficial femoral and proximal popliteal arteries. Tack implants exert low radial force and are associated with minimal metal burden, which reduces the mechanical stress on the arterial wall in treating dissections after balloon angioplasty. This study investigated the safety and effectiveness of the Tack Endovascular System in patients with dissections after drug-coated balloon (DCB) angioplasty. METHODS: The Tack Optimized Balloon Angioplasty III (TOBA III) study is a prospective, multicenter, single-arm study in which patients who underwent percutaneous transluminal angioplasty with the Medtronic IN.PACT Admiral DCB (Medtronic, Dublin, Ireland) and experienced dissection after angioplasty were treated with Tack implants. The primary end points were freedom from major adverse events at 30 days and primary patency at 12 months. RESULTS: A total of 201 patients were enrolled in the trial, 169 with standard-length lesions (≥20 mm and ≤150 mm) and 32 with long-length lesions (>150 mm and ≤250 mm). Safety and effectiveness results were favorable compared with historical benchmarks at 12 months in the standard-lesion cohort. Notably, patients in the standard-lesion cohort experienced 95.0% primary patency, 97.5% freedom from clinically driven target lesion revascularization, 100% freedom from amputation, and 100% survival at 12 months (P < .0001). Primary patency in long-lesion patients was 89.3%, freedom from clinically driven target lesion revascularization was 96.8%, and freedom from amputation was 100% at 12 months. Device success was achieved in 95.8% (182/190) and 97.7% (43/44) of devices deployed into standard-lesion and long-lesion patients, respectively. Procedural success was 99.4% (168/169) and 100% (44/44) in the standard-lesion and long-lesion cohorts, respectively, with only one bailout stent placed in the entire population. CONCLUSIONS: The Tack Endovascular System is a safe and effective treatment option for patients with dissections after angioplasty in the superficial femoral and proximal popliteal arteries, with high patency, low rates of secondary intervention, and low incidence of bailout stenting when it is used in combination with DCB.

Purpose: To assess the practical application and acute outcomes of the Tack Endovascular System for infrainguinal dissection repair in a real-world setting. Materials and Methods: Fifty-one consecutive patients who underwent endovascular revascularization for symptomatic peripheral artery disease and experienced 63 dissections requiring treatment were included in the prospective, single-center, single-arm study between January and June 2019. Thirty-nine (76.5%) lesions were ≥10 cm in length, 33 (64.7%) were totally occluded, and 13 (25.5%) were severely calcified. Fifty-six (88.9%) dissections were classified as severe. Dissections were treated either by means of the 6-F above-the-knee (ATK) or the 4-F below-the-knee (BTK) Tack Endovascular System. Observational outcomes were conditions and scopes of application. Clinical outcomes were acute technical and procedural success as well as safety. Results: Lesions were revascularized with 2.3±0.8 attempts such as standard balloon angioplasty, drug-coated balloon angioplasty, atherectomy, and/or lithotripsy. The Endovascular System was applied in 60 (95.2%) of 63 dissections. All dissections of the femoral artery were treated with the ATK system, and all infrapopliteal dissections with the BTK system. Both systems were successfully applied in popliteal artery dissections. Dissection length predicted the number of Tack implants deployed. Technical success was achieved in 98.3% (59 of 60 dissections). No major adverse event or device-related complication occurred during the procedure. Conclusion: Acute results in effectiveness and safety of the Tack Endovascular System for infrainguinal dissection repair in a real-world setting are promising.

Purpose: To examine whether the combination of orbital atherectomy (OA) and drug-coated balloons (DCB) can lead to superior procedural and 2-year outcomes compared with DCB only in heavily calcified femoropopliteal (FP) lesions. Materials and Methods: A retrospective chart review was conducted to identify patients treated with DCB only or OA+DCB for de novo FP lesions at a single center over a 4-year period (2014-2017). In the observation period, 113 patients met the inclusion criteria: 63 treated with DCB only (mean age 69.0±8.6 years; 62 men) vs 50 treated with OA+DCB (mean age 70.3±7.1 years; 48 men). The OA+DCB group had higher calcification rates (78% with severe calcification vs 37% in the DCB only group). Propensity score matching (PSM) was used to adjust for baseline differences between the 2 groups. Cox regression analysis was used to compare the follow-up outcomes between lesions treated with OA+DCB vs DCB only. Results: No difference in procedural complications or success was found. After PSM adjustment, the OA+DCB group was associated with lower bailout stenting rates (39.4% vs 66.7% in the DCB only group; p=0.026). The 2 groups had similar long-term outcomes, although the OA+DCB arm had a trend toward reduced TLR rates that did not reach statistical significance. The Kaplan-Meier estimates for 2-year freedom from TLR were 76.1% for the OA+DCB group vs 55.5% for the DCB only group (p=0.109). Conclusion: OA+DCB is a safe and effective combination for the treatment of calcified FP lesions. The combined therapy decreased the bailout stenting rates in the adjusted analysis. Larger cohorts and randomized trials are needed to examine OA efficacy in FP lesions.

Purpose: To report the 36-month outcomes from the prospective, multicenter, single-arm IN.PACT Global Study (ClinicalTrials.gov identifier NCT01609296) evaluating the performance of the IN.PACT Admiral drug-coated balloon (DCB) in real-world patients with femoropopliteal occlusive disease. Materials and Methods: The IN.PACT Global Study was conducted at 64 international sites and enrolled 1535 patients with complex lesions, which included bilateral disease, multiple lesions, de novo in-stent restenosis, long lesions, and chronic total occlusions. The predefined full clinical cohort included 1406 patients (mean age 68.6 years; 67.8% men) with claudication or rest pain treated with the study DCB. Mean lesion length was 12.09±9.54 cm; 18.0% had in-stent restenosis, 35.5% were totally occluded, and 68.7% were calcified. Freedom from clinically-driven target lesion revascularization (CD-TLR) was evaluated through 36 months. The safety composite endpoint was freedom from device- and procedure-related death through 30 days and freedom from major target limb amputation and clinically-driven target vessel revascularization within 36 months. All safety and revascularization events were reviewed by an independent clinical events committee. Results: The Kaplan-Meier estimate of freedom from CD-TLR through 36 months was 76.9%. The composite safety endpoint was achieved in 75.6% of patients. The 36-month all-cause mortality rate was 11.6%, and the major target limb amputation rate was 1.0%. The Kaplan-Meier estimate of freedom from CD-TLR through 36 months was significantly lower in patients with chronic limb-threatening ischemia (CLTI) compared with claudicants (67.6% vs 78.0%; p=0.003). Lesions affecting both the superficial femoral artery (SFA) and popliteal artery had lower Kaplan-Meier freedom from CD-TLR through 36 months (69.2%) than either isolated SFA (79.7%) or popliteal artery lesions (76.5%; log- rank p<0.001). Predictors of CD-TLR through 36 months included increased lesion length, reference vessel diameter ≤4.5 mm, in-stent restenosis, bilateral disease, CLTI, and hyperlipidemia. Conclusion: DCB angioplasty with the IN.PACT Admiral DCB for femoropopliteal disease in a diverse and complex real-world population is associated with sustained clinical efficacy and low rates of reinterventions at 3 years after the initial procedure.

Purpose: To evaluate the safety and efficacy of the novel SELUTION sustained-limus-release (SLR) drug-eluting balloon (DEB) in the treatment of femoropopliteal lesions. Materials and Methods: Between October 2016 and May 2017, 50 subjects (mean age 69.6±10.4 years; 29 men) with symptomatic moderate to severe lower limb ischemia (Rutherford categories 2 or 3) were enrolled at 4 German centers for the SELUTION SLR first-in-human trial (ClinicalTrials.gov NCT02941224). The SELUTION SLR utilizes micro-reservoirs (biodegradable polymer spheres containing sirolimus) embedded within an amphipathic membrane coated onto an angioplasty balloon. The biodegradable reservoirs are transferred to the target vessel lumen during brief balloon inflation. The primary trial objective was comparison of angiographic late lumen loss at 6 months against an objective performance criterion (OPC) value of 1.04 mm for uncoated balloon angioplasty. Secondary endpoints included device, procedural, and clinical success; clinical and imaging assessments of primary patency and restenosis; functional assessments including Rutherford category and ankle-brachial index (ABI); and major adverse events [composite of cardiovascular mortality, index limb amputation, target limb thrombosis, and clinically-driven target lesion revascularization (CD-TLR)]. Results: At 6 months, median angiographic late lumen loss following SELUTION SLR treatment was 0.19 mm (range -1.16 to 3.07). Mean angiographic late lumen loss (n=34) was 0.29±0.84 mm (95% CI -0.01 to 0.58), significantly lower than the 1.04-mm OPC value (p<0.001). The rate of primary patency by duplex ultrasound was 88.4%, and freedom from angiographic binary restenosis was 91.2%. Through 6 months, there was significant improvement over baseline in Rutherford categories (p<0.001) and in ABI measurements (p<0.001). A single case (2%) of CD-TLR occurred at 5 months. There were no other major adverse events. Conclusion: Through 6 months, the SELUTION SLR DEB appears to inhibit restenosis effectively and safely, improving outcomes in subjects with symptomatic femoropopliteal disease.

Purpose: To further investigate the safety and performance of the Passeo-18 Lux drug-coated balloon (DCB) for the treatment of atherosclerotic infrainguinal disease under real-world conditions. Materials and Methods: BIOLUX P-III is an international, prospective, observational registry (ClinicalTrials.gov identifier NCT02276313) conducted at 41 centers in Europe, Asia, and Australia with follow-up visits at 6, 12, and 24 months. Of 700 patients (mean age 70.0±10.2 years; 439 men) with 863 lesions in the all-comers cohort, 330 (47.1%) patients had diabetes and 234 (37.7%) had chronic limb-threatening ischemia. The majority (79.3%) of lesions were in the femoropopliteal segment; of all lesions, 645 (74.9%) were calcified and 99 (11.5%) had in-stent restenosis (ISR). The mean lesion length was 84.7±73.3 mm. The primary clinical endpoint was major adverse events (MAEs) within 6 months, a composite of device- and procedure-related mortality through 30 days, major target limb amputation, and clinically-driven target lesion revascularization (TLR). The primary performance endpoint was clinically-driven TLR within 12 months. Results: At 6 and 12 months, freedom from MAEs was 94.0% and 89.5% in the all-comers cohort: 95.0% and 91.2% in the femoropopliteal group and 95.3% and 88.0% in the ISR subgroup, respectively. Freedom from clinically-driven TLR at 12 months was 93.1% in the all-comers cohort, 93.9% in the femoropopliteal lesions, and 89.4% for ISR lesions. All-cause mortality was 6.1% in the all-comers cohort: 5.9% in both the femoropopliteal and ISR subgroups. There were no device- or procedure-related deaths at up to 12 months. The Rutherford category improved in >80% of all subgroups at 12 months. Conclusion: In a real-world patient population, the safety and performance of the Passeo-18 Lux DCB for the treatment of atherosclerotic infrainguinal lesions are maintained, with good performance outcomes and low complication rates at 12 months.

Purpose: To report a propensity score analysis comparing outcomes of the Supera interwoven nitinol stent to bare nitinol stents (BNS) in the femoropopliteal segment. Materials and Methods: A retrospective study was conducted utilizing data extracted from the Excellence in Peripheral Artery Disease (XLPAD) registry (ClinicalTrials.gov identifier NCT01904851) on 871 patients (mean age 65.1 years; 713 men) who underwent femoropopliteal balloon angioplasty with either Supera stent implantation in 118 limbs or other contemporary BNS in 753 limbs between January 2006 and December 2016. All patients in both groups were matched for baseline demographic and clinical characteristics in a 1:1 propensity score matching using the nearest neighbor method to create the 118-patient matched BNS cohort. One-year outcomes included all-cause mortality, target vessel revascularization (TVR), and target limb revascularization (TLR). An additional core laboratory analysis was conducted to measure the deployed length of Supera stents. Results: In unmatched data, the Supera stent group had a numerically lower rate of TVR (7.6% vs 13.4%, p=0.08) and a significantly lower 1-year TLR rate (7.6% vs 16.2%, p=0.02) compared to the BNS group. Both groups had similar 1-year mortality (2.5% vs 2.7%, p=0.9). Kaplan-Meier analysis demonstrated that the Supera group had a significantly lower risk of TVR (p=0.02) and TLR (p=0.002) than the BNS group. After propensity matching, the 1-year TVR estimate was lower for Supera stents (7.6% vs 12.7%, p=0.08) and significantly lower for TLR (7.6% vs 13.6%, p=0.04) than the BNS group. There was no statistically significant association between Supera stent elongation (>10% of the labeled stent length) and 1-year risk of TLR (p=0.6). Conclusion: Supera stent usage in femoropopliteal intervention was associated with reduced risk of 1-year repeat target limb revascularization compared with BNS treatment in both unmatched and matched cohorts.
