RESUMO
BACKGROUND: Previous reports have shown comparable outcomes between drug-eluting stents (DESs) and drug-coated balloons (DCBs) for treating femoropopliteal artery (FPA) lesions; however, DCB outcomes include approximately 10% to 50% bailout stents. Therefore, comparing DESs and DCBs is not simple. The aim of this study was to compare the clinical outcomes of DESs and DCBs in patients with symptomatic FPA disease. MATERIALS AND METHODS: Using the registries of 7 institutions, we retrospectively reviewed the records of 1356 patients who underwent endovascular therapy for FPA with DESs (n=333; Eluvia, 74.0%; Zilver PTX stent, 26.0%) or DCBs without bailout stents (n=1023; IN.PACT, 67.6%; Lutonix, 32.4%). The primary outcome was the 1-year primary patency comparison between DESs and DCBs, using propensity score matching. The severity of the dissection pattern after predilatation (none or grades A-C) was included as an explanatory variable for matching. Patients with grade D dissections were excluded from the main analysis and assessed independently. RESULTS: After matching, the 1-year primary patency between DESs and DCBs was similar (88.8% vs 85.2%, p=0.31). By contrast, perioperative complications were frequent with DES, compared with DCB (5.1% vs 2.2%, p=0.005), and the intravascular ultrasound-evaluated minimum luminal area was significantly larger with DES than with DCB (19 mm2 vs 14 mm2, p<0.001). In the supplemental analysis of lesions with grade D dissection, the 1-year primary patency was significantly higher with DES than with DCB (86.1% vs 55.1%, p=0.014). CONCLUSION: In FPA lesions without severe dissection (ie, no dissection or grade A-C dissection), DESs and DCBs showed comparable 1-year primary patency in matched populations. However, DCBs did not perform well with severe dissection (ie, grade D or more). CLINICAL IMPACT: The results of this study clearly define the appropriate boundaries for the "leaving nothing behind" strategy. Clinicians can now more clearly differentiate between the use of DES and DCB, based on the results of lesion preparation. Further prospective investigations with well-designed trials and larger populations are necessary to confirm these findings.
RESUMO
BACKGROUND: Endovascular therapy (EVT) is often performed for diffuse femoropopliteal lesions. This study investigated 3-year patency and clinical outcomes in patients with EVT-treated femoropopliteal lesions >25 cm. METHODS: This retrospective multicenter registry analyzed patients who presented with lower extremity artery disease having femoropopliteal lesions >25 cm who underwent EVT between 2017 and 2021. The primary outcome was restenosis 3 years after EVT. RESULTS: Overall, 504 patients with 614 lesions undergoing EVT for diffuse femoropopliteal lesions were enrolled. The prevalence of restenosis was 184.3 per 1000 lesion-years. Kaplan-Meier estimate of freedom from restenosis was 58.6% at 3 years. In the multivariate Poisson regression model, female sex (adjusted incidence risk ratio: 1.54; p = 0.003), cilostazol use (0.44; p < 0.001), revascularization history (1.87; p = 0.001), P3 involvement (2.09; p < 0.001), and reference vessel diameter <5 mm (1.88; p < 0.001) were associated independently with restenosis risk. The accumulation of these factors was associated with a lower rate of freedom from restenosis; the Kaplan-Meier estimates of the rates were 49.3% and 22.4% in the subgroups with two and more risk factors, respectively, while they were 81.1% in patients without any risk factors and 70.3% in those with one risk factor. CONCLUSIONS: Female sex, nonuse of cilostazol, revascularization history, P3 involvement, and small vessels were associated with high restenosis risk after EVT for diffuse femoropopliteal lesions. Although patients with multiple risk factors have a low patency rate, EVT offers an acceptable patency rate for those with fewer risk factors.
RESUMO
PURPOSE: Clinical trials have demonstrated that high-dose drug-coated balloon (HD-DCB) and polymer-based drug-eluting stent (PB-DES) treatments for femoropopliteal (FP) artery disease have favorable outcomes. However, which one would be better remained unrevealed. METHODS: This study used the databases of 2 large-scale multicenter prospective drug-coated balloon (DCB) and drug-eluting stent (DES) registries. The study included 2470 patients with symptomatic FP lesion treated with IN.PACT Admiral DCB or Eluvia DES at 69 centers. A propensity-score-based paired analysis was conducted. Primary endpoint was 1-year restenosis rate. Secondary endpoints were 1-year reocclusion rate, target lesion revascularization (TLR), acute thrombosis, bypass conversion, major amputation, major adverse limb event (MALE), and all-cause death. RESULTS: A total of 1535 patients were treated with HD-DCB, and 935 patients were treated with PB-DES. The propensity-score matching extracted 678 pairs, with no remarkable intergroup difference in baseline characteristics. The 1-year restenosis rate was significantly lower in the PB-DES group than in the HD-DCB group (16.0% vs 22.0%, p=0.016). The other endpoints (reocclusion rate, TLR, acute thrombosis, bypass conversion, major amputation, MALE, and all-cause death) did not differ between the groups. No baseline characteristics had any significant interaction effect on the association of HD-DCB vs PB-DES with restenosis risk (all p>0.05). CONCLUSIONS: This study demonstrated that the 1-year TLR, reocclusion rate, and other endpoints did not differ between the PB-DES group and the HD-DCB group despite the lower restenosis in the PB-DES group. CLINICAL IMPACT: One-year restenosis rate was significantly lower in the polymer-based DES group than in the high-dose DCB group for foemoropopliteal disease. However, there is no difference in the other endpoints between two groups.
RESUMO
OBJECTIVE: To validate the Japanese below-the-knee (J-BTK) chronic total occlusion (CTO) score for the prediction of successful guidewire crossing (S-GC) in angiographic evaluation. METHODS: A prospective, multicenter, nonrandomized study examined 751 consecutive BTK CTOs in 497 patients treated with endovascular therapy in 16 Japanese medical centers from April 2021 to March 2022. The cohort was classified into 2 groups: an S-GC group and a failed guidewire crossing group. RESULTS: The J-BTK CTO score, which assigned one point to "Blunt type at the proximal entry point," one point to "Calcification at the proximal entry point," one point to "Reference vessel diameter <2.0 mm," one point to "CTO length ≥200 mm," and two points to "No outflow of the target vessel," was used to categorize BTK CTOs into 4 grades with varying probabilities of S-GC: grade A (J-BTK CTO score of 0 and 1), grade B (score of 2 and 3), grade C (score of 4 and 5), and grade D (score of 6). Rates of S-GC in each grade (grades A, B, C, and D) were 97.5%, 89.1%, 62.5%, and 27.3%, respectively. The area under the receiver-operating characteristic curve for S-GC was 0.8304. Although the previous J-BTK CTO study enrolled only de novo lesions, both de novo and restenotic lesions were evaluated in this study. De novo lesions have a lower chance of S-GC (odds ratio: 0.24, 95% confidence interval: 0.09-0.67) in the multivariate analysis, and the area under the receiver-operating characteristic curve of the modified J-BTK CTO score, which additionally assigned two points to "De novo lesion," was 0.846. The modified J-BTK CTO score showed an appropriate calibration (Hosmer-Lemeshow P = .957). CONCLUSIONS: The J-BTK CTO score and the modified J-BTK CTO score predict the probability of an S-GC of BTK CTOs and stratify the difficulty of endovascular therapy for BTK CTOs in angiographic evaluation.
RESUMO
PURPOSE: In the present trial, the 24-month safety and effectiveness of the TCD-17187 drug-coated balloon (DCB) for the treatment of atherosclerotic lesions in the superficial femoral artery (SFA) and proximal popliteal artery (PA) were evaluated in Japanese patients. METHODS: This was a prospective, multicenter, core laboratory-adjudicated, single-arm trial. From 2019 to 2020, 121 patients with symptomatic peripheral artery disease were enrolled. The primary effectiveness outcome measure was primary patency. The safety outcome measure was the major adverse event (MAE) rate. RESULTS: Age was 74.5 ± 7.3 years, and diabetes mellitus was present in 67.5%. Lesion length and reference vessel diameter (RVD) were 106.0 ± 52.6 mm and 5.2 ± 0.8 mm, respectively. Chronic total occlusion (CTO) and bilateral calcification rate (Grade 3 and 4 by peripheral arterial calcium scoring system (PACSS)) were 17.5% and 50.8%, respectively. The 24-month primary patency rate by duplex ultrasound was 71.3%, while freedom from clinically driven target lesion revascularization (CD-TLR) was 87.0%. The MAE rate was 13.2% and all events consisted of CD-TLR. There were no instances of device- or procedure-related deaths major amputations throughout the 24 months. Multivariate Cox proportional hazards regression analysis revealed significant differences associated with loss of primary patency in the following characteristics: CTO, restenotic lesion and RVD. CONCLUSION: This trial confirmed the safety and effectiveness of TCD-17187 DCB for atherosclerotic lesions of the SFA and/or proximal PA for up to 24 months. LEVEL OF EVIDENCE: Level 3, Cohort study.

BACKGROUND: Drug-eluting devices improved outcomes of endovascular therapy (EVT) for femoropopliteal lesions, but mainly for de novo lesions. Endovascular therapy for in-stent restenosis/occlusion (ISR/O) is challenging, and large trials and long-term data are not well reported. MATERIALS AND METHODS: This study is a physician initiated, multicenter, and retrospective design. From 7 Japanese institutes, 3635 femoropopliteal cases were enrolled in the study. Among these, 346 cases of first ISR/O were studied. We defined drug-coated-balloon, drug-eluting stent, and covered stent as New devices. Balloon angioplasty and bare nitinol stent were included in the control group. RESULTS: The propensity score matching extracted 112 pairs. At 12 months, the primary patency rate was 80.3% in the new device group and 52.7% in the control group, and there was a significant intergroup difference (P = .004). However, at 36 months, the rate was 43.3% vs 39.2%, with no significant difference (P = .090). No baseline characteristics had any significant interaction effect (all P > .05). CONCLUSIONS: The New devices were more effective than the control group for ISR/O at 1 year, but caught up at 3 years.
RESUMO
This multicenter retrospective study assessed the clinical outcomes of endovascular therapy (EVT) using a drug-coated balloon (DCB) that was larger than the predilatation balloons for femoropopliteal artery lesions. We analyzed 1140 cases with symptomatic peripheral artery disease that underwent EVT with DCB for femoropopliteal lesions between 2017 and 2021. The primary endpoint was procedural failure, defined as a composite of deteriorated dissection and bailout stenting. The secondary endpoints included deteriorated dissection, bailout stenting, restenosis, and target lesion revascularization. We performed propensity score matching to compare the clinical outcomes between EVT with a DCB which was larger than the predilatation balloon (larger DCB) and EVT with a DCB which was not (nonlarger DCB). We assigned 276 cases to the larger DCB group and 864 cases to the nonlarger DCB group. Procedural failure was observed in 75 cases, whereas restenosis occurred in 282 cases during a mean follow-up period of 12.7 ± 9.7 months. Propensity score matching extracted 273 pairs with no intergroup difference in baseline characteristics, except the predilatation balloon size. Procedural failure (9.2% versus 6.1%, P = 0.11), deteriorated dissection and bailout stenting proportion (both P > 0.05), and 1-year rates of freedom from restenosis (82.4% versus 84.1%, P = 0.59) and target lesion revascularization (89.7% versus 90.4%, P = 0.83) showed no significant difference between the larger and nonlarger DCB groups. Irrespective of whether the DCB size was larger than the predilatation balloon, no difference was observed in either procedural or clinical outcomes.

BACKGROUND: Impaired quality of life (QoL) is prevalent among patients with chronic thromboembolic pulmonary hypertension (CTEPH) despite improved survival due to medical advances. We clarified the physical QoL of patients with CTEPH with mildly elevated pulmonary hemodynamics and evaluated its determinants using a database of patients with CTEPH evaluated for hemodynamics during exercise. METHODS: The QoL was measured in 144 patients with CTEPH (age, 66 (58-73) years; men/women, 48/96) with mildly elevated mean pulmonary artery pressure (<30 mm Hg) at rest after treatment with balloon pulmonary angioplasty and/or pulmonary endarterectomy using the Short-Form 36 (SF-36) questionnaire. The enrolled patients were divided into 2 groups: physical component summary (PCS) scores in the SF-36 over 50 as PCS-good and those under 50 as PCS-poor. RESULTS: The median PCS in SF-36 score was 43.4 (IQR 32.4-49.5) points. The PCS-poor group (n = 110) was older and had lower exercise capacity and SaO2 during exercise. PCS scores were correlated with 6-minute walk distance (rs=0.40, p < 0.001), quadriceps strength (rs=0.34, p < 0.001), peak VO2 (rs=0.31, p < 0.001), SaO2 at rest (rs=0.35, p < 0.001) and peak exercise (rs=0.33, p < 0.001), home oxygen therapy usage (rs=-0.28, p = 0.001), and pulmonary vascular resistance at peak exercise (rs=-0.26, p = 0.002). CONCLUSIONS: The impairment of physical QoL was common in patients with CTEPH with improved hemodynamics; exercise capacity, hypoxemia, and hemodynamic status during exercise were related to the physical QoL.

Introduction: The safety and effectiveness of the GORE VIABAHN Endoprosthesis for treatment of symptomatic patients with peripheral artery disease (PAD) and complex femoropopliteal (FP) lesions was assessed in a real-world Japanese practice setting. Methods: A prospective, multicenter, postmarket surveillance study was conducted from 2016 to 2017 at 64 sites in Japan. Symptomatic patients with PAD and FP lesions ⩾ 10 cm and reference vessel diameters ranging from 4.0 to 7.5 mm were eligible for enrollment. Outcome measures evaluated at 5 years were primary patency (PP), primary-assisted patency (PAP), secondary patency (SP), freedom from target lesion revascularization (fTLR), occurrence of device- or procedure-related serious adverse events (SAEs), and stent fractures. Results: A total of 321 patients were enrolled and were a mean age of 73.9 ± 8.7 years; 77.3% were men and 26.5% had chronic limb-threatening ischemia (CLTI). The mean lesion length was 23.6 ± 6.6 cm and the frequency with TASC II C/D lesions and chronic total occlusions was 86.6% and 70.4%, respectively. The Kaplan-Meier estimated PP, PAP, SP, and fTLR at 5 years was 62.4%, 74.1%, 82.3%, and 75.9%, respectively. The mean ankle-brachial index was 0.92 ± 0.15 and the mean improvement in Rutherford class was 2.3 ± 1.4, which was maintained through 5 years. The rate of cumulative device- or procedure-related SAEs through 5 years was 19.9% with only 9.3% of those occurring after the first year. No stent fractures were observed through 5 years by x-ray evaluation. Conclusion: The 5-year safety and efficacy outcomes of the endoprosthesis were clinically acceptable for treating complex FP lesions in a real-world cohort of Japanese patients with PAD.

BACKGROUND: Whether intraluminal drug-coated balloon (DCB) angioplasty is superior to subintimal DCB angioplasty regarding femoropopliteal (FP) chronic total occlusion (CTO) outcomes has not been systematically determined. OBJECTIVES: The aim of this study was to compare the 1-year clinical outcomes of intraluminal and subintimal DCB angioplasty for the treatment of patients with symptomatic FP CTO. METHODS: This subanalysis of POPCORN (Prospective Multi-Center Registry of Drug-Coated Balloon for Femoropopliteal Disease) evaluated 469 lesions in 469 symptomatic patients with lower extremity artery disease who presented with FP CTO and underwent DCB treatment. Wire passage (intraluminal vs subintimal) was evaluated using intravascular ultrasound. The outcome measure, 1-year freedom from restenosis, was compared between subintimal and intraluminal DCB angioplasty groups after propensity score matching analysis. The Institutional Review Boards of participating centers approved this study. Informed consent was obtained from the participants or their families. RESULTS: During the median follow-up period of 14.2 months, restenosis occurred in 140 patients. After propensity score matching, the subintimal group had a significantly lower 1-year rate of freedom from restenosis than the intraluminal group (77.0% vs 84.2%, respectively; P = 0.024). Interaction analysis revealed a more marked increased risk for restenosis in the subintimal DCB angioplasty group in patients with severe calcification, low-dose DCB use, or smoking. CONCLUSIONS: The present study revealed that intraluminal DCB angioplasty was superior to subintimal DCB angioplasty for FP CTO treatment, with a significantly better 1-year rate of freedom from restenosis.

PURPOSE: Surgical thromboendarterectomy has been the gold standard treatment for common femoral artery (CFA) disease. However, endovascular therapy (EVT) is conducted in certain patients with CFA lesions because of multiple comorbidities. The interwoven nitinol stent (IWS) has been developed to prevent stent fracture. Thus, this study aimed to evaluate the feasibility of EVT using IWS for CFA lesions in clinical practice. MATERIALS AND METHODS: This retrospective multicenter registry analyzed patients who had symptomatic lower-extremity artery disease due to CFA lesions and underwent EVT using IWS between 2019 and 2021. The primary endpoint was restenosis 2 years after EVT. RESULTS: This study enrolled a total of 177 patients with 196 CFA lesions. The 2-year estimate of freedom from restenosis was 88.0%. The 2-year freedom rates from the target-lesion revascularization, major amputation, and all-cause death were 92.9%, 99.0%, and 75.2%, respectively. The clinical features significantly associated with restenosis risk were the reference vessel diameter (RVD, per 1.0 mm, hazard ratio [HR], 0.24 [0.08-0.70]; p=0.009), external iliac artery (EIA) involvement (HR=4.03 [1.56-10.4]; p=0.004), superficial femoral artery (SFA) involvement (HR=3.05 [1.00-9.25]; p=0.049), body mass index (BMI; per 1.0, HR=0.85 [0.73-0.99]; p=0.032), occlusion of deep femoral arteries (DFAs) at baseline (HR=7.89 [2.04-30.5]; p=0.003), and chronic limb-threatening ischemia (CLTI, HR=2.63 [1.02-6.78]; p=0.045). Their significant association was also confirmed by the random survival forest analysis. During a median follow-up of 12.0 months, guiding sheaths were inserted via CFAs implanted IWSs in 73 cases (37.2%), and no patients had cannulation-related complications, such as failed hemostasis, fracture of IWS, and stent occlusion. CONCLUSIONS: Endovascular therapy using IWS in CFA lesions showed acceptable 2-year patency rates at 88.0% and might preserve the arterial access via the ipsilateral CFAs. Small RVD, involving EIA and SFA lesions, emaciation, occluded DFA, and CLTI are associated with poor 2-year patency rates following EVT, thus, IWS implantation in CFA lesions may be an option for patients unsuitable for surgical revascularization. CLINICAL IMPACT: This retrospective multicenter registry enrolled 177 patients with 199 CFA lesions treated with EVT using interwoven nitinol stents, because surgical thromboendarterectomy was difficult due to their multiple comorbidities. The 2-year estimate of freedom from restenosis was acceptable at 88.0%. The 2-year freedom rate from major amputation was also high at 99.0%. Moreover, during a median follow-up of 12.0 months, guiding sheaths were inserted via CFAs implanted IWSs in 73 cases, and no patients had cannulation-related complications such as failed hemostasis, fracture of IWS, and stent occlusion.
RESUMO
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are widely used in cardiology and are effective in treating acute coronary syndrome (ACS). Their effects on unstable plaque in patients with ACS remains unclear. This study aimed to examine the effectiveness of SGLT2is in coronary plaque based on optical coherence tomography (OCT) images and the prognosis of ACS with type 2 diabetes mellitus. This retrospective study included 109 patients in the total cohort and 29 patients in the OCT cohort. Based on SGLT2i administration after ACS, the total cohort was categorized into non-SGLT2i (n = 69) and SGLT2i (n = 40) groups. The OCT cohort had 15 and 14 patients in the non-SGLT2i and SGLT2i groups, respectively. The OCT images of unstable plaque were analyzed in nonstented lesions during ACS catheterization and at the 6-month follow-up. The total cohort was assessed after 1 year for major adverse cardiovascular events, including all-cause mortality, revascularization, cerebrovascular disease, and heart failure hospitalization. SGLT2is improved unstable lesions with a significantly thicker fibrous cap (48 ± 15 µm vs 26 ± 24 µm, p = 0.005), reduced lipid arc (-29 ± 12° vs -18 ± 14°, p = 0.028), higher % decrease in total lipid arc (-35 ± 13% vs -19 ± 18%, p = 0.01), and lower major adverse cardiovascular event incidence (log-rank p = 0.023, hazard ratio 4.72 [1.08 to 20.63]) and revascularization rate (adjusted hazard ratio 6.77 [1.08 to 42.52]) than the non-SGLT2i group. In conclusion, SGLT2is can improve the markers of plaque stability and may improve the prognosis in patients with type 2 diabetes mellitus.

BACKGROUND: The mechanism underlying a poor prognosis in patients with lower-extremity artery disease (LEAD) with heart failure is unknown. We examined the prognostic impact of the left ventricular ejection fraction (LVEF) in patients with LEAD who underwent endovascular therapy (EVT).MethodsâandâResults: From August 2014 to August 2016, 2,180 patients with LEAD (mean age, 73.2 years; male, 71.9%) underwent EVT and were stratified into low-LVEF (LVEF <40%; n=234, 10.7%) and not-low LVEF groups. In the low- vs. not-low LVEF groups, there was a higher prevalence of heart failure (i.e., history of heart failure hospitalization or New York Heart Association functional class III or IV symptoms) (44.0% vs. 8.3%, respectively), diabetes mellitus, chronic kidney disease, below-the-knee lesion, critical limb ischemia, and incidence of major cardiovascular and cerebrovascular events (MACCEs) and major adverse limb events (MALEs) (P<0.001, all). Low LVEF independently predicted MACCEs (hazard ratio: 2.23, 95% confidence interval: 1.63-3.03; P<0.001) and MALEs (hazard ratio: 1.85, 95% confidence interval: 1.15-2.96; P=0.011), regardless of heart failure (P value for interaction: MACCEs: 0.27; MALEs: 0.52). CONCLUSIONS: Low LVEF, but not symptomatic heart failure, increased the incidence of MACCEs and MALEs. Intensive cardiac dysfunction management may improve LEAD prognosis after EVT.

Clinical guidelines for pulmonary hypertension (PH) recommend shared decision-making and individualized treatment. However, patient perspectives on PH treatment goals, preference toward a decision-making style of treatment, and adoption of shared decision-making remain unclear. This cross-sectional questionnaire-based study assessed the patients' preferred and actual participation role in treatment decision-making, rated on 5 scales (ranging from passive [patients leave all decisions to physicians] to active [patients make the decision after physicians show patients several options]) and evaluated the concordance between preferred and actual participation roles. The important factors underlying patients' perspectives in treatment decision-making (i.e., prognosis; symptom, financial, family, and social burdens; patient values; and physician recommendation) were evaluated. Univariate logistic regression analysis was performed to determine the patients with a positive preference toward "physician recommendation" in treatment decision-making. Among 130 patients with PH (median age: 58 years; mean pulmonary arterial pressure: 23 mm Hg; 27.7% were males), 59.2% preferred that "physicians make the decision regarding treatment after showing patients therapeutic options (i.e., intermediate between passive and active roles)." The patient-preferred and actual participation roles in decision-making had moderate agreement (Cohen's kappa = 0.46). The most important factor in treatment decisions was "symptom burden reduction" (93.8%). Although 85.0% of patients chose "physician recommendation" as an important factor, 49.6% chose "alignment with my values." The determinants of patients who chose "physician recommendation" were less severe hemodynamics and better functional capacity. In conclusion, patients with PH preferred that the "physicians make the decision after showing patients therapeutic options" and prioritized physician recommendation over their values.

Background: Previous studies have revealed the risk factors for femoral pseudoaneurysms (FPA). Most data on FPA are based on coronary and peripheral interventions, with limited studies focusing on atrial fibrillation (AF) ablation. However, patient backgrounds, anticoagulation regimens, and vascular access methods differ. In addition, a standard for managing FPA after AF ablation remains elusive due to the difficult nature of achieving thrombosis in pseudoaneurysms. Methods: This single-center, retrospective, observational study included 2805 consecutive patients who underwent AF ablation between January 2016 and December 2021. All patients underwent femoral artery and vein punctures. Puncture sites were checked 1 day post-procedure. Results: A total of 23 FPA patients were identified during the study period. Multivariate logistic regression analysis showed that hypertension (odds ratio 4.66, 95% confidence interval: 1.38-15.71; p = .0032) and warfarin use (odds ratio 3.83, 95% confidence interval: 1.40-10.45; p = .021) were significantly associated with the occurrence of FPA. The compression success rate was low (22%). There were nine and six patients in the endovascular treatment (EVT) and ultrasound-guided thrombin injection (UGTI) groups, respectively. The success rates were 100% and 84% in the EVT and UGTI groups, respectively. The length of hospital stay after FPA treatment was 2.1 days in the EVT group and 1.3 days in the thrombin group. Conclusion: We must be careful about post-procedural FPA, especially for hypertension and warfarin-using patients. Treatment of pseudoaneurysms with anticoagulants is unlikely to achieve hemostasis, and an early switch to invasive treatments, such as EVT, should be considered.
RESUMO
BACKGROUND: Randomized trials have shown comparable outcomes between second-generation low-dose drug-coated balloons (LD-DCBs) and first-generation high-dose drug-coated balloons (HD-DCBs); but the trial patients had low clinical complexity, and there were no comparisons in medically complex populations. OBJECTIVES: The aim of this study was to compare outcomes between an LD-DCB (Ranger; 2.0 µg/mm2) and an HD-DCB (IN.PACT; 3.5 µg/mm2) in patients with symptomatic femoropopliteal artery disease. METHODS: PROSPECT MONSTER (Prospective Comparison of Second-Generation Low-Dose Drug-Coated Balloon With High-Dose Drug-Coated Balloon) was a prospective, multicenter, nonrandomized trial that prospectively collected data from 581 patients who underwent endovascular therapy with the LD-DCB (n = 370) or the HD-DCB (n = 211) for symptomatic femoropopliteal artery disease (Rutherford classes 2-5). The primary outcome was the 1-year primary patency of the LD-DCB in comparison with that of the HD-DCB, as evaluated using propensity score matching. The incidence of impaired flow after drug-coated balloon application was also evaluated. RESULTS: Propensity score matching extracted 163 pairs (358 and 163 patients in the LD-DCB and HD-DCB groups, respectively), with no significant intergroup difference in baseline characteristics. The 1-year primary patency rates in the matched population were similar between the LD-DCB and HD-DCB groups (87.0% [95% CI: 82.5%-91.7%] vs 81.3% [95% CI: 74.8%-88.5%]; HR: 0.93; 95% CI: 0.55-1.59; P = 0.79), as was the incidence of impaired flow (13.6% vs 9.8%; OR: 1.46; 95% CI: 0.78-2.73; P = 0.24). No baseline characteristics had any significant interaction effects on the association of the LD-DCB vs the HD-DCB and 1-year restenosis risk. CONCLUSIONS: LD-DCBs demonstrate efficacy and safety comparable with HD-DCBs in patients with complex clinical backgrounds, suggesting that drug-coated balloon treatment using a lower dose may be possible.

PURPOSE: To investigate the 1-year and 2-year clinical outcomes of interwoven stent (IWS) implantation for symptomatic femoropopliteal arterial disease with calcification. MATERIAL AND METHODS: This prospective multicenter study evaluated 308 limbs (63% with the peripheral arterial calcium scoring system 3 and 4 severe calcification and 87% with ≥180° calcification on intravascular ultrasound) of 299 patients (diabetes in 66.9%, chronic renal failure in 52.8%, and dialysis in 49.2%) who underwent IWS (Supera; Abbott, Abbott Park, Illinois) implantation after sufficient predilation (residual stenosis < 30%) for calcified femoropopliteal lesions. The primary outcome measure was primary patency (freedom from restenosis) at 1 and 2 years, whereas the secondary outcome measure included freedom from clinically driven target lesion revascularization (CD-TLR). Clinical parameters associated with loss of patency were explored. RESULTS: Kaplan-Meier analysis showed that primary patency was 88.2% (95% confidence interval [CI], 84.5%-92.1%) at 1 year and 80.8% (95% CI, 76.1%-85.8%) at 2 years. The CD-TLR-free rate was 96.5% and 94.8% at 1 and 2 years, respectively. The characteristics associated with loss of patency were restenotic lesion with and without stent implantation (adjusted hazard ratio, 1.96 and 2.40; P = .047 and .041, respectively), chronic total occlusion (adjusted hazard ratio, 1.88; P = .022), and popliteal involvement (adjusted hazard ratio, 2.60; P = .002). CONCLUSIONS: The implantation of IWS after sufficient predilation for calcified femoropopliteal atherosclerotic disease demonstrated clinically acceptable primary patency.

BACKGROUND: Although majority of cases with chronic total occlusion (CTO) in femoro-popliteal lesion were treated with antegrade approach only, some lesions require alternative approach due to its complexity. Bi-directional approach is useful on endovascular therapy (EVT) for CTO; however guidewire passage through the lesion is impossible in some challenging cases. The present case shows a successful re-entry technique utilizing two snare catheters from an antegrade and retrograde access site (double snare piecing technique). CASE PRESENTATION: A 79-year-old woman with right leg intermittent claudication (Rutherford category IV), who had undergone unsuccessful EVT for popliteal CTO, required another EVT for the worsening symptom. Following the failed conventional crossing technique (wire knuckle technique, intravascular-ultrasound-guided wiring, and controlled antegrade and retrograde subintimal tracking technique), two snare catheters were placed and the snare loops were pierced by a puncture needle percutaneously. After an 0.014 wire was inserted into the needle, the needle was withdrawn. The wire was pulled from the retrograde side and was externalized. Then, the antegrade snare catheter was pulled and externalized, to make the wire across the lesion. After that, a microcatheter was advanced along the externalized wire from the retrograde side and cross the lesion. The wire was replaced with a new wire, which completely created pull-through system. After the hemostasis by balloon inflation and lesion preparation, this procedure was completed with an endoluminal-covered stent and two inter-woven stents. The re-entry site was covered by the inter-woven stent. Her symptoms improved after the procedure, and the lesion has not developed restenosis at 2-years follow-up. CONCLUSIONS: This re-entry technique of puncturing two snare loops (double snare piercing technique) might be effective for achieving successful passage through challenging femoropopliteal CTO cases.
RESUMO
Background The symptom for identification of pulmonary arterial hypertension (PAH) is dyspnea on exertion, with a concomitant decrease in exercise capacity. Even patients with hemodynamically improved PAH may have impaired exercise tolerance; however, the effect of central and peripheral factors on exercise tolerance remains unclear. We explored the factors contributing to exercise capacity and ventilatory efficiency in patients with hemodynamically normalized PAH after medical treatment. Methods and Results In total, 82 patients with PAH (age: median 46 [interquartile range, 39-51] years; male:female, 23:59) and mean pulmonary arterial pressure ≤30 mm Hg at rest were enrolled. The exercise capacity, indicated by the 6-minute walk distance and peak oxygen consumption, and the ventilatory efficiency, indicated by the minute ventilation versus carbon dioxide output slope, were assessed using cardiopulmonary exercise testing with a right heart catheter. The mean pulmonary arterial pressure was 21 (17-25) mm Hg, and the 6-minute walk distance was 530 (458-565) m, whereas the peak oxygen consumption was 18.8 (14.8-21.6) mLêmin-1êkg-1. The multivariate model that best predicted 6-minute walk distance included peak arterial mixed venous oxygen content difference (ß=0.46, P<0.001), whereas the best peak oxygen consumption predictors included peak cardiac output (ß=0.72, P<0.001), peak arterial mixed venous oxygen content difference (ß=0.56, P<0.001), and resting mean pulmonary arterial pressure (ß=-0.25, P=0.026). The parameter that best predicted minute ventilation versus carbon dioxide output slope was the resting mean pulmonary arterial pressure (ß=0.35, P=0.041). Quadriceps muscle strength was moderately correlated with exercise capacity (6-minute walk distance; ρ=0.57, P<0.001; peak oxygen consumption: ρ=0.56, P<0.001) and weakly correlated with ventilatory efficiency (ρ=-0.32, P=0.007). Conclusions Central and peripheral factors are closely related to impaired exercise tolerance in patients with hemodynamically normalized PAH.
