RESUMO
BACKGROUND AND AIMS: Patients with unprovoked venous thromboembolism (VTE) have a high recurrence risk, and guidelines suggest extended-phase anticoagulation. Many patients never experience recurrence but are exposed to bleeding. The aim of this study was to assess the performance of the Vienna Prediction Model (VPM) and to evaluate if the VPM accurately identifies these patients. METHODS: In patients with unprovoked VTE, the VPM was performed 3 weeks after anticoagulation withdrawal. Those with a predicted 1-year recurrence risk of ≤5.5% were prospectively followed. Study endpoint was recurrent VTE over 2 years. RESULTS: A total of 818 patients received anticoagulation for a median of 3.9 months. 520 patients (65%) had a predicted annual recurrence risk of ≤5.5%. During a median time of 23.9 months, 52 patients had non-fatal recurrence. The recurrence risk was 5.2% [95% confidence interval (CI) 3.2-7.2] at 1 year and 11.2% (95% CI 8.3-14) at 2 years. Model calibration was adequate after 1 year. The VPM underestimated the recurrence risk of patients with a 2-year recurrence rate of >5%. In a post-hoc analysis, the VPM's baseline hazard was recalibrated. Bootstrap validation confirmed an ideal ratio of observed and expected recurrence events. The recurrence risk was highest in men with proximal deep-vein thrombosis or pulmonary embolism and lower in women regardless of the site of incident VTE. CONCLUSIONS: In this prospective evaluation of the performance of the VPM, the 1-year rate of recurrence in patients with unprovoked VTE was 5.2%. Recalibration improved identification of patients at low recurrence risk and stratification into distinct low-risk categories.

OBJECTIVE: Women and underrepresented minorities (URMs) who are at an increased risk of presenting with severe peripheral artery disease (PAD) and have different responses to treatment compared with non-Hispanic White males yet are underrepresented in PAD research. METHODS: ELEGANCE is a global, prospective, multi-center, post-market registry of PAD patients treated with drug-eluting device that aims to enroll at least 40% women and 40% URMs. The study design incorporates strategies to increase enrollment of women and URMs. Inclusion criteria are age ≥18 years and treatment with any commercially available Boston Scientific Corporation drug-eluting device marketed for peripheral vasculature lesions; exclusion criterion is life expectancy <1 year. RESULTS: Of 750 patients currently enrolled (951 lesions) across 39 sites, 324 (43.2%) are female and 350 (47.3%) are URMs (21.6% Black, 11.2% Asian, 8.5% Hispanic/Latino, and 5.3% other). Rutherford classification is distributed differently between sexes (P = .019). Treatment indication differs among race/ethnicity groups (P = .003). Chronic limb-threatening ischemia was higher for Black (38.3%) and Hispanic/Latino (28.1%) patients compared with non-Hispanic White (21.8%) and Asian patients (21.4%). De-novo stenosis was higher in Asian patients (92.3%) compared with Black, non-Hispanic White, and Hispanic/Latino patients (72.2%, 68.7%, and 77.8%, respectively; P < .001). Mean lesion length was longest for Black patients (162.7 mm), then non-Hispanic White (135.2 mm), Asian (134.8 mm), and Hispanic/Latino patients (128.1 mm; P = .008). CONCLUSIONS: Analyses of data from the ELEGANCE registry show that differences exist in baseline disease characteristics by sex and race/ethnicity; these may be the result of other underlying factors, including time to diagnosis, burden of undermanaged comorbidities, and access to care.

RESUMO
OBJECTIVES: The aim of this study was to assess the mid-term outcomes of the use of drug-coated balloons (DCBs) to treat infrainguinal peripheral arterial disease (PAD) in patients with dyslipidemia. METHODS: BIOLUX P-III is a prospective, international, multicenter, all-comers registry-based study that was conducted at 44 sites with follow-ups at 6, 12 and 24 months. The present study is a subgroup analysis comparing the outcomes associated with endovascular revascularization with those associated with Passeo-18 lux DCBs in patients with and without dyslipidemia. The proportions of patients free from major adverse events (defined as device- or procedure-related mortality within 30 days, clinically driven target lesion revascularization (CD-TLR) and major target limb amputation), target vessel revascularization, and patient-reported outcomes within 24 months postintervention were compared between the two groups. RESULTS: A total of 876 patients with symptomatic PAD who underwent peripheral revascularization with DCBs and had information on their dyslipidemia status were included; 588 of those patients had dyslipidemia. There was no difference in the proportion of patients free from MAEs between the groups. The percentages of patients who were 6, 12 and 24 months free from CD-TLR were significantly lower in the dyslipidemia group than in the nondyslipidemia group (86.3% vs 91.9% at 2 years, p = .0183). Similarly, the percentage of patients free from target vessel revascularization was lower in the dyslipidemia group at all timepoints (83.3% vs 89.3% at 2 years, p = .0203). There was no difference in mortality or major or minor limb amputation rates. Other secondary outcomes were similar between the groups. CONCLUSIONS: Compared to those without dyslipidemia, patients with symptomatic PAD and dyslipidemia who underwent revascularization with a Passeo-18 lux DCB had greater rates of CD-TLR and TVR. However, having dyslipidemia did not increase the risk of mortality or limb amputation. CLINICAL TRIAL REGISTRATION: NCT02276313.
RESUMO
Background: Guidelines recommend walking trainings for peripheral arterial disease (PAD) management. Supervised walking training is superior to walking advise to improve the walking distance. Telehealth service with nurse support may close this gap. Patients and methods: This study introduces a telehealth service, "Keep pace!", which has been developed for patients with symptomatic PAD (Fontaine stage IIa and IIb), enabling a structured home-based walking training while monitoring progress via an app collecting unblinded account of steps and walking distance in self-paced 6-minute-walking-tests by geolocation tracking to enhance intrinsic motivation. Supervision by nurses via telephone calls was provided for 8 weeks, followed by 4 weeks of independent walking training. Patient satisfaction, walking distance and health-related quality of life were assessed. Results: 19 patients completed the study. The analysis revealed an overall high satisfaction with the telehealth service (95.4%), including system quality (95.1%), information quality (94.4%), service quality (95.6%), intention to use (92.8%), general satisfaction with the program (98.4%) and health benefits (95.8%). 78.9% asserted that the telehealth service lacking nurse calls would be less efficacious. Pain-free walking distance (76.3±36.8m to 188.4±81.2m, +112.2%, p<0.001) as well as total distance in 6-minute-walking test (308.8±82.6m to 425.9±107.1m, +117.2%, p<0.001) improved significantly. The telehealth service significantly reduced discomfort by better pain control (+15.5%, p=0.015) and social participation (+10.5%, p=0.042). Conclusions: In conclusion, patients were highly satisfied with the telehealth service. The physical well-being of the PAD patients improved significantly post vs. prior the telehealth program.

Endovascular interventions and diagnostic examinations using iodinated contrast media (ICM) are standard of care in current vascular medicine. Although ICM use is generally considered safe, it may be associated with adverse reactions, vary from minor disturbances to rare, but severe life-threatening complications. This position paper of European Society of Vascular Medicine integrates current knowledge and summarizes the key information related to the use of intravascular ICM, serving as recommendation on prevention and management of acute, late, and very late adverse reactions. It should help the health professionals in all fields of vascular medicine to make decisions in daily practice for safe use of contrast media.

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.

BACKGROUND: Patients with peripheral artery disease who have undergone lower-extremity revascularization are at high risk for major adverse limb and cardiovascular events. The efficacy and safety of rivaroxaban in this context are uncertain. METHODS: In a double-blind trial, patients with peripheral artery disease who had undergone revascularization were randomly assigned to receive rivaroxaban (2.5 mg twice daily) plus aspirin or placebo plus aspirin. The primary efficacy outcome was a composite of acute limb ischemia, major amputation for vascular causes, myocardial infarction, ischemic stroke, or death from cardiovascular causes. The principal safety outcome was major bleeding, defined according to the Thrombolysis in Myocardial Infarction (TIMI) classification; major bleeding as defined by the International Society on Thrombosis and Haemostasis (ISTH) was a secondary safety outcome. RESULTS: A total of 6564 patients underwent randomization; 3286 were assigned to the rivaroxaban group, and 3278 were assigned to the placebo group. The primary efficacy outcome occurred in 508 patients in the rivaroxaban group and in 584 in the placebo group; the Kaplan-Meier estimates of the incidence at 3 years were 17.3% and 19.9%, respectively (hazard ratio, 0.85, 95% confidence interval [CI], 0.76 to 0.96; P = 0.009). TIMI major bleeding occurred in 62 patients in the rivaroxaban group and in 44 patients in the placebo group (2.65% and 1.87%; hazard ratio, 1.43; 95% CI, 0.97 to 2.10; P = 0.07). ISTH major bleeding occurred in 140 patients in the rivaroxaban group, as compared with 100 patients in the placebo group (5.94% and 4.06%; hazard ratio, 1.42; 95% CI, 1.10 to 1.84; P = 0.007). CONCLUSIONS: In patients with peripheral artery disease who had undergone lower-extremity revascularization, rivaroxaban at a dose of 2.5 mg twice daily plus aspirin was associated with a significantly lower incidence of the composite outcome of acute limb ischemia, major amputation for vascular causes, myocardial infarction, ischemic stroke, or death from cardiovascular causes than aspirin alone. The incidence of TIMI major bleeding did not differ significantly between the groups. The incidence of ISTH major bleeding was significantly higher with rivaroxaban and aspirin than with aspirin alone.

OBJECTIVE: The Tack Endovascular System is a minimal-metal dissection repair device that is purpose-built to treat post-percutaneous angioplasty (PTA) arterial dissections in patients with peripheral arterial disease (PAD). The Tack Optimized Balloon Angioplasty (TOBA) III trial evaluated the safety and effectiveness of the Tack Endovascular System in patients with superficial femoral artery (SFA) and/or proximal popliteal artery (PPA) dissection after PTA with a drug-coated balloon (DCB). The objective of this study is to report the results in the standard- (SL) and long-lesion (LL) cohorts through 24 months. DESIGN: The TOBA III study was a prospective, multicenter, single-arm study including patients suffering from Rutherford category 2-4 PAD. Outcomes were assessed according to pre-specified lesion length in SL ( ≥ 20 mm and ≤150 mm) and LL ( > 150 mm and ≤250 mm) cohorts. Follow-up was through 24 months. RESULTS: TOBA III enrolled 201 patients, 169 patients in the SL cohort and 32 in the LL cohort. At 24 months, the Kaplan-Meier estimates of freedom from major adverse events were 91.7% and 82.6% for the SL cohort and LL cohort, respectively. Kaplan-Meier estimates of freedom from clinically driven-target lesion revascularization (CD-TLR) were 92.3% in the SL cohort and 82.6% in the LL cohort. At 24 months, 78.8% of SL patients and 69.2% of LL patients experienced an improvement of >2 Rutherford categories (both cohorts p < 0.001). The baseline ankle-brachial index improved from 0.68 ± 0.18 to 0.93 ± 0.16 in the SL (p < 0.001) and from 0.62 ± 0.23 to 0.87 ± 0.15 in the LL cohort (p < 0.001) at 24 months. CONCLUSION: The 24-month results of the TOBA III trial support the safety and effectiveness of the Tack Endovascular System in patients who required post-PTA dissection repair in the SFA and PPA following DCB angioplasty for claudication and rest pain. In both the SL and LL cohorts, Tack placement was associated with sustained freedom from CD-TLR through 24 months as well as sustained improvements in Rutherford categories, ankle-brachial index, and quality of life.
RESUMO
INTRODUCTION: The presence of severe arterial calcification is associated with less favorable outcomes in terms of procedural and clinical success as well as higher rates of major adverse limb events. Recent studies incorporating rotational atherectomy for effective preparation of severely calcified lesions demonstrate beneficial procedural outcomes by obtaining maximal luminal gain and improved long-term outcomes. METHODS: This prospective single-center, observational study includes patients with severely calcified femoropopliteal lesions with chronic limb ischemia Rutherford 1-5 between January 2017 and July 2019, who underwent atherectomy using the Jetstream Atherectomy system, followed by drug-coated balloon angioplasty. Lesion calcification was categorized by the Peripheral Arterial Calcium Scoring System (PACSS), whereas lesion complexity was classified by the Transatlantic Inter-Society Consensus (TASC). Safety and efficacy aspects in terms of vessel injury, thromboembolism, and clinical success were systematically analyzed up to 12 months of follow-up (FU). RESULTS: In 162 consecutive patients, 210 non-stented and 22 stented lesions were treated. Twelve (7.4%) patients received bail-out stenting. Mean lesion length was 24.2±4.8 cm; 51% were chronic total occlusions (mean occlusion length 18.2±5.1 cm). TASC C lesions were present in 38 patients (23.5%) and TASC D lesions in 124 patients (76.5%). The mean PACCS score was 3.3±0.9. Device success was achieved in 88%; procedural success was noted in 99% of the lesions. Embolic protection device was used in 11.7%. Perforation or dissection occurred in none of the cases. Asymptomatic peripheral embolization was noted in 10 patients (6.2%). Clinical FU at 12 months was available in 157 of 162 patients (96.9%). At 12 month FU, (1) mean Rutherford classification at baseline of 3.7±0.6 significantly dropped to 1.0±0.9 (p<0.05), (2) baseline mean anke-brachial index (ABI) of 0.4±0.1 significantly increased to 0.8±0.2 (p<0.05), (3) 92.6% were free from target lesion revascularization (TLR), (4) 95.1% were free from target vessel revascularization (TVR), and (5) binary restenosis measured by duplex occurred in 22 patients (13.6%). Multivariate analyses showed lesion length as predictive of stent placement (p=0.02), whereas both lesion length (p=0.006) and PACCS score (p=0.02) are predictive of clinical success. CONCLUSION: Rotational atherectomy in combination with drug-coated balloon (DCB) can be safely performed in long, calcified (non-) occlusive lesions with a relatively low rate of bail-out stenting and favorable clinical mid-term results. CLINICAL IMPACT: In this prospective, single arm study we demonstrated that combination treatment using rotational atherectomy and DCB is safe and effective in complex and calcified TASC C/D femoropopliteal lesions in patients with claudication or CLTI in a real-world clinical setting. Despite mean lesion length of >20cm and a relatively high rate of chronic total occlusions, the rate of bail-out stenting was surprisingly low (7.4%), whereas the rates of freedom from TLR and TVR were surprisingly high. Thus, our study may encourage vascular specialists to choose an endovascular -first approach even in such complex and calcified femoropopliteal lesions and occlusions in daily clinical practice.
RESUMO
BACKGROUND: The randomized Chocolate Touch Study demonstrated that in patients undergoing treatment of femoropopliteal artery lesions, the Chocolate Touch drug-coated balloon (DCB) was safe and had superior efficacy at 12 months compared with the Lutonix DCB. We report the prespecified diabetes subanalysis comparing outcomes among patients with and without diabetes mellitus (DM). METHODS: Patients with claudication or ischemic rest pain (Rutherford class 2-4) were randomized to Chocolate Touch or Lutonix DCB. The primary efficacy endpoint 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 bailout stenting). The primary safety endpoint was freedom from major adverse events at 12 months, a composite of target limb-related death, major amputation, or reintervention. RESULTS: A total of 313 patients (38% DM [n=119]) were randomized to either Chocolate Touch (n=66/152) or Lutonix DCB (n=53/161). Among patients with DM, DCB success was 77.2% and 60.5% (p=0.08), and in non-DM patients, DCB success was 80% and 71.3% (p=0.2114) for the Chocolate Touch and Lutonix DCB, respectively. The primary safety endpoint was similar for both cohorts regardless of DM status (interaction test, p=0.96). CONCLUSIONS: This randomized trial demonstrated similar safety and efficacy for the treatment of femoropopliteal disease with the Chocolate Touch DCB compared with using the Lutonix DCB regardless of DM status at 12 months. CLINICAL IMPACT: This substudy of the Chocolate Touch Study demonstrated similar safety and efficacy for treatment of femoropopliteal disease of the Chocolate Touch DCB compared with the Lutonix DCB regardless of diabetes (DM) status at 12 months. Endovascular therapy has become the therapy of choice for the treatment of most symptomatic femoropopliteal lesions regardless of DM status. These results give clinicians another option when treating femoropopliteal disease in this high-risk patient population.
RESUMO
PURPOSE: To investigate the clinical performance and safety of the Passeo-18 Lux drug-coated balloon (DCB) in complex femoropopliteal Trans-Atlantic Inter-Society Consensus (TASC) C and D lesions in an all-comers patient population. MATERIAL AND METHODS: Data from BIOLUX P-III SPAIN, a prospective, national, multicenter, postmarket all-comers registry conducted from 2017 to 2019, and a matching long lesion subgroup from the BIOLUX P-III All-Comers global registry conducted from 2014 to 2018 were pooled for analysis. The primary safety end point was freedom from major adverse events (MAEs) at 6 months, and the primary performance end point was freedom from clinically driven target lesion revascularization (fCD-TLR) at 12 months, both adjudicated by an independent clinical events committee. RESULTS: A total of 159 patients, of whom 32.7% had critical limb ischemia, were included in the Passeo-18 Lux long lesion cohort. The mean lesion length was 248.5 mm ± 71.6, and the majority were occluded (54.1%), calcified (87.4%), and of type TASC C (49.1%) or TASC D (50.9%). Freedom from MAEs was 90.6% (95% CI, 84.6-94.3) at 6 months and 83.9% (95% CI, 76.7-89.0) at 12 months. fCD-TLR was 84.4% (95% CI, 77.3-89.5) at 12 months. Freedom from target limb major amputation was 98.6% (95% CI, 94.6-99.7), and all-cause mortality was 5.3% (95% CI, 2.7-10.4) at 12 months. There were no device- or procedure-related deaths or amputations up to the 12-month follow-up. CONCLUSION: Passeo-18 Lux DCB is safe and effective for the treatment of long femoropopliteal lesions in a real-word setting.

OBJECTIVES: Periodontal disease occurs frequently in patients with limited cutaneous systemic sclerosis (lcSSc) while data about underlying pathways contributing to periodontal changes are scarce. The aim of this study was to evaluate periodontal disease and to investigate its association with endothelial dysfunction and clinical changes in patients with lcSSc. METHODS: In 38 lcSSc patients and 38 controls, periodontal status was evaluated by disease-specific questionnaire, dental examination including bleeding on probing (BOP), pocket depth, and plaque index, and dental panoramic radiograph. Periodontopathogen bacteria were collected subgingivally using paper points and interleukin-1 (IL-1) gene polymorphisms were evaluated using buccal swabs. Endothelial dysfunction was measured by flow-mediated dilatation, pulse-wave velocity and biochemical analysis, including arginine metabolites and endothelial microparticles. Additionally, lcSSc-specific clinical changes and parameters were recorded. RESULTS: Periodontitis was present in 31 patients with lcSSc (81.6%) and in 27 controls (71.1%) (p = .280). LcSSc patients had a lower teeth number (p = .039) and Eikenella corrodens was to a higher degree detectable in patients with lcSSc (p = .041) while the remaining periodontal parameters revealed no differences between both cohorts. Significant correlations between parameters of arterial stiffness, EUSTAR index, number of teeth and BOP were observed (all p < .05). Detection of Prevotella intermedia was associated with selected IL-1 gene polymorphisms (p = .032) and Porphyromonas gingivalis was associated with severe periodontitis (p = .041). CONCLUSION: Periodontal disease may occur frequently in patients with lcSSc and may be associated with arterial stiffness and with SSc activity.

Aortic dilatation (AD) occurs in up to 30% of patients with giant cell arteritis (GCA). Reliable biomarkers for AD development, however, are still absent. The aim of this exploratory study was to evaluate whether immunological parameters are associated with the occurrence of AD in GCA. Cross-sectional study on 20 GCA patients with AD, 20 GCA patients without AD, and 20 non-GCA controls without AD measuring leukocytes, neutrophils, lymphocytes, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum amyloid A (SAA), interferon (IFN)-α, IFN-γ, IFN-γ-induced protein 10 (IP-10), interleukin (IL) 5, IL-8, IL-10, IL-17A, IL-18, IL-1 receptor antagonist, tumor necrosis factor (TNF)-α, platelet-derived growth factor (PDGF), L-selectin, P-selectin, and soluble intercellular adhesion molecule 1 (sICAM-1). AD was measured by aortic contrast-enhanced computed tomography and defined by enlargement of the aorta above population-based aortic diameters adjusted by age, gender, and body surface area. No significant differences were observed between GCA patients with AD and GCA patients without AD concerning levels of leukocytes, neutrophils, lymphocytes, CRP, ESR, SAA, IL-8, IL-18, PDGF, IP-10, selectins, and sICAM-1. Values of IFN-α, IFN-γ, IL-5, IL-10, IL-17A, IL-1 receptor antagonist, and TNF-α were all below the detection limits in more than 70% of subjects. Lymphocytes and CRP revealed positive correlations with the diameter of the thoracic descending aorta. Immunological parameters were not useful to conclude on the presence of AD in GCA. Further studies are required to test if CRP and lymphocytes may be useful to predict future development of AD in GCA.

OBJECTIVES: The TOBA (Tack Optimized Balloon Angioplasty) II trial is a prospective, single-arm, multicenter study that investigated Tack treatment for patients with dissection after angioplasty in the superficial femoral artery and/or proximal popliteal artery. The Tack device is a nitinol-based, short (6 mm), stent-like implant with low outward force that can be deployed in a targeted fashion to treat vascular dissection. TOBA II primary results through 12 months have been published previously. This report provides follow-up safety and efficacy results through 24 months (RC). METHODS: The TOBA II trial enrolled 213 patients with Rutherford classification 2 to 4 and a de novo or non-stented restenotic lesion in the superficial femoral artery and/or proximal popliteal artery who developed a dissection of any grade after treatment with plain balloon or drug-coated balloon (DCB) angioplasty. Participants were followed for 30 days, 6 months, 12 months, 24 months, and 36 months following the procedure. Evaluations included clinically driven target lesion revascularization (CD-TLR), ankle-brachial index, Rutherford classification, peripheral artery questionnaire, quality of life assessed by the EQ-5D-3L, and the Walking Impairment Questionnaire. RESULTS: At enrollment, mean age was 68.2 ± 9.1 years, 70.9% were male, and 95.8% of patients were categorized as RC 2 or 3. The distribution of balloon types in the study were standard balloons: 42.3%; and drug-coated balloons: 57.7%. At 24-month follow-up, 167 patients (78.4%) had available data. The overall survival rate at 24 months was 95.4% and there were no major amputations during this time. After 24 months of follow-up, the Kaplan-Meier freedom from CD-TLR was 77.7%. Rutherford classification, ankle-brachial index, and quality of life were significantly improved compared with baseline through 24 months. CONCLUSIONS: The TOBA II 24-month data demonstrate durable intermediate-term outcomes with the use of the Tack Endovascular System. Tack deployment was a safe and effective therapeutic option for dissection repair following angioplasty.
RESUMO
BACKGROUND: Results from the BIOLUX P-III registry have demonstrated favourable outcomes of Passeo-18 Lux™ (Biotronik®, Buelach, Switzerland) drug-coated balloon in treating obstructive infrainguinal peripheral artery disease, but it has not been established if Asians would benefit to the same extent as non-Asians. METHODS: A subgroup analysis was performed on the 24-month data comparing the Asian cohort (AC) to non-Asian cohort (NAC). RESULTS: AC included 49 patients with 77 lesions. AC was significantly younger (65.6 vs 70.3 years, p < 0.05), had more diabetes (87.8% vs 45.3%, p < 0.05), and was more likely to present with CLTI (73.5% vs 35.3%, p < 0.001) compared to NAC. They had significantly longer mean target lesions (115 vs 86.9 mm, p = 0.006), and received significantly higher paclitaxel doses (10.7 vs 7.2 mg, p = 0.0005). Device, technical and procedural successes were 125/125(100%), 95/97(97.5%) and 45/49(91.8%), respectively. There was no significant difference in target lesion revascularization rates between groups (10.5% vs 12%, p = 0.91). However, the AC had more major adverse events (30.2% vs 16.1%, p = 0.001), amputations (26.3% vs 6.2%, p < 0.05) and mortality (37.9% vs 10.6%, p < 0.05) at 24 months. CONCLUSION: Passeo-18 Lux™ use was efficacious in Asians, but was associated with higher adverse events, amputations and mortality rates, likely attributable to poorer patient comorbidities and more extensive PAD.

Tobacco consumption is one of the most important risk factors for cardiovascular disease. Despite all efforts to curb any form of smoking, the number of e-cigarette users is still rising more than tabacco smoking decreases. E-cigarettes are often advertised as less harmful than regular cigarettes and helpful for smoking cessation. But e-cigarettes are not risk-free and their use causes vascular damage. There is concern about long-term health risks of e-cigarettes or when non-smokers use them as first nicotine contact. Furthermore, their use for smoking cessation is discussed controversially. To optimize treatment and medical counselling of current smokers and e-cigarette users, we present an evidence-based overview of the most important issues of e-cigarette use from a vascular medicine point of view. The key messages are presented as a position statement of the German Society of Vascular Medicine and endorsed by the European Society of Vascular Medicine.

BACKGROUND: Patients with peripheral artery disease (PAD) are at heightened risk of acute limb ischemia (ALI), a thrombotic event associated with amputation, disability, and mortality. Previous lower extremity revascularization (LER) is associated with increased ALI risk in chronic PAD. However, the pattern of risk, clinical correlates, and outcomes after ALI early after LER are not well-studied, and effective therapies to reduce ALI post-LER are lacking. METHODS: The VOYAGER PAD trial (Vascular Outcomes Study of ASA [Acetylsalicylic Acid] Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for PAD; rNCT02504216) randomized patients with PAD undergoing LER to rivaroxaban 2.5 mg twice daily or placebo on a background of low-dose aspirin. The primary outcome was a composite of ALI, major amputation of vascular cause, myocardial infarction, ischemic stroke, or cardiovascular death. ALI was prospectively ascertained and adjudicated by a blinded committee. The cumulative incidence of ALI was calculated using Kaplan-Meier estimates, and Cox proportional hazards models were used to generate hazard ratios and associated CIs. Analyses were performed as intention-to-treat. RESULTS: Among 6564 patients followed for a median of 2.3 years, 382 (5.8%) had a total of 508 ALI events. In placebo patients, the 3-year cumulative incidence of ALI was 7.8%. After multivariable modeling, previous LER, baseline ankle-brachial index <0.50, surgical LER, and longer target lesion length were associated with increased risk of ALI. Incident ALI was associated with subsequent all-cause mortality (hazard ratio [HR], 2.59 [95% CI, 1.98-3.39]) and major amputation (HR, 24.87 [95% CI, 18.68-33.12]). Rivaroxaban reduced ALI relative to placebo by 33% (absolute risk reduction, 2.6% at 3 years; HR, 0.67 [95% CI, 0.55-0.82]; P=0.0001), with benefit starting early (HR, 0.45 [95% CI, 0.24-0.85]; P=0.0068 at 30 days). Benefit was present for severe ALI (associated with death, amputation, or prolonged hospitalization and intensive care unit stay, HR, 0.58 [95% CI, 0.40-0.83]; P=0.003) and regardless of LER type (surgical versus endovascular revascularization, P interaction=0.42) or clopidogrel use (P interaction=0.59). CONCLUSIONS: After LER for symptomatic PAD, ALI is frequent, particularly early after LER, and is associated with poor prognosis. Low-dose rivaroxaban plus aspirin reduces ALI after LER, including ALI events associated with the most severe outcomes. The benefit of rivaroxaban for ALI appears early, continues over time, and is consistent regardless of revascularization approach or clopidogrel use.
