RESUMO
ABSTRACT: In risk-stratifying patients with atrial fibrillation (AF), physicians rely heavily on clinical parameters that provide risk scores and determine treatment strategies. There has been increasing research on potential biomarkers in the blood that could more accurately determine both risk of complications in AF and risk of incidence of AF. This review highlights the clinical significance of 5 novel biomarkers that have been shown to be linked to AF. These biomarkers are carbohydrate antigen 125, galectin-3, growth differentiation factor-15, a member of the interleukin 1 receptor family, IL1RL1 (ST2), and N-terminal pro B-type natriuretic peptide.

OBJECTIVES: The aim of this study was to examine the use of saphenous vein grafts (SVGs) for retrograde crossing during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The use of SVGs for retrograde crossing during CTO PCI has received limited study. METHODS: A total of 1,615 retrograde CTO PCIs performed between 2012 and 2019 at 25 centers were examined. Clinical, angiographic, and technical characteristics and procedural outcomes were compared among retrograde cases via SVGs (SVG group) versus other collateral vessels (non-SVG group). RESULTS: Retrograde CTO PCI via SVGs was performed in 189 cases (12%). Patients in the SVG group were older (mean age 70 ± 9 years vs. 64 ± 10 years; p < 0.01) and had higher rates of prior myocardial infarction (62% vs. 51%; p < 0.01) and prior PCI (81% vs. 70%; p < 0.01). They were more likely to have moderate or severe calcification (81% vs. 65%; p < 0.01) and moderate or severe tortuosity (53% vs. 44%; p = 0.02) and had similar J-CTO (Multicenter CTO Registry in Japan) scores (3.2 ± 1.0 vs. 3.1 ± 1.1; p = 0.13) but higher PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) scores (4.7 ± 1.7 vs. 3.1 ± 1.1; p < 0.01). Technical (85% vs. 78%; p = 0.04) and procedural (81% vs. 74%; p = 0.04) success rates were higher in the SVG group, with no difference in in-hospital major adverse events (6.4% vs. 4.4%; p = 0.22). Contrast volume was lower in the SVG group (225 ml [173 to 325 ml] vs. 292 ml [202 to 400 ml]; p < 0.01). CONCLUSIONS: Use of SVGs for retrograde crossing is associated with higher rates of technical and procedural success and similar rates of in-hospital major adverse cardiac events compared with retrograde CTO PCI via other collateral vessels.

BACKGROUND: The contemporary limb outcomes and costs of stent-based vs non-stent based strategies in endovascular revascularization of femoropopliteal (FP) peripheral artery disease (PAD) are not well understood. METHODS AND RESULTS: We present data from the ongoing United States multicenter Excellence in Peripheral Artery Disease Registry between 2006-2016 to compare stent vs non-stent treatment outcomes and associated costs in FP interventions. A total of 2910 FP interventions were performed in 2162 patients (mean age, 66 years), comprising 1339 stent based (superficial femoral artery, 93%) in 1007 patients and 1571 non-stent interventions (superficial femoral artery, 85%) in 1155 patients. A growing trend for non-stent based interventions and a declining trend in repeat revascularization rate at 1 year were observed across years of registry enrollment. Stent implantation was the prevailing strategy in treating longer FP lesions (mean length, 152 mm vs 105 mm; P<.001) and chronic total occlusions (65% vs 40%; P<.001), while stent implantation was employed less frequently when treating in-stent restenotic lesions (14% vs 20%; P<.001). Stent and non-stent interventions had similar 1-year limb outcomes in all-cause death, target-limb revascularization, target-vessel revascularization, and major or minor amputation. The average procedure costs for the stent group were significantly higher than the non-stent group ($6215 vs $4790; P<.001). CONCLUSION: There is a growing trend for non-stent FP artery interventions, with a significant decline in 1-year target-limb revascularization rates over time. One-year limb outcomes in stent-based compared to non-stent interventions are similar; however, at a significantly higher procedural cost.

BACKGROUND: Intravascular ultrasound (IVUS) is considered the gold standard in diagnosing common iliac vein (CIV) compression. The presence of >50% surface area reduction by IVUS is considered significant compression by most operators. Thus, we evaluated the role of computed tomography angiography (CTA) and venography in diagnosing CIV compression when compared to IVUS. METHODS: All patients who underwent CTA of the pelvis with venous filling phase, IVUS, and venography within a few weeks apart to evaluate for symptomatic CIV compression from one cardiovascular practice were retrospectively reviewed. Quantitative vascular analysis was performed on all images obtained to determine (1) percent stenosis (PS) by venogram; and (2) minimal lumen area (MLA) and PS by CTA and IVUS at the compression site (using ipsilateral distal CIV as reference area). Spearman's rank correlation, paired t-tests, or signed rank tests were performed as appropriate to compare between values of MLA and PS among the three different imaging modalities. RESULTS: A total of 96 patients were included (62.5% females; mean age, 62.3 ± 14.8 years). A significant correlation was found between MLA-CTA and MLA-IVUS (Spearman's rho, 0.27; P=.01) and PS-CTA and PS-IVUS (Spearman's rho, 0.327; P<.01). A significant correlation was also found between PS-venogram and PS-IVUS (Spearman's rho, 0.471; P<.001). MLA-CTA and MLA-IVUS had a median difference of +41 mm² (95% CI, 25.0-57.5; P<.001) whereas PS-CTA and PS-IVUS were not statistically different (median difference, -5.6 mm²; 95% CI, -12.2 to 0.7). Furthermore, PS-IVUS and PS-venogram had a median difference of +15.2% (95% CI, 10.4-20.1; P<.001). CONCLUSION: PS-venogram correlates with PS-IVUS, but venogram underestimates the PS by an average of 15.2%. In contrast, PS-CTA and PS-IVUS are not statistically different despite an over-estimation of MLA by CTA when compared to IVUS. Therefore, we conclude that PS-CTA and not PS-venogram can be used to predict PS on IVUS.

BACKGROUND: The long-term outcome of Jetstream atherectomy (JA) with or without adjunctive drug coated balloons (DCB) in a real-world setting remains unknown. We report 16-month target lesion revascularization (TLR) rates on patients treated for femoropopliteal (FP) artery disease with JA in a single center by one operator. METHODS: From 1/1/12 to 8/24/16 a total of 311 procedures were performed with atherectomy by a single operator at a single center. Of these procedures, 75 met inclusion and exclusion criteria. This report evaluates the outcomes of these 75 patients treated at index and who were followed up to 16â¯months. The primary endpoint of the study was clinically driven TLR. Patients were stratified by the use of DCB (vs angioplasty (PTA)) post-JA. TLR was calculated by excluding bailout stenting as TLR. Survival analysis for TLR over time was plotted. RESULTS: 75 patients (49.3% male, mean age 68.0â¯years, 54.7% diabetes) with de novo or restenotic FP lesions whose symptoms were classified as Rutherford category I-V were enrolled. Adjunctive PTA was performed on 50 patients (26 de novo, 13 in-stent restenosis, 3 non-stent restenosis, 8 mixed lesions) and adjunctive DCB (LUTONIX® 24, IN.PACT® 1) on 25 patients (21 de novo, 1 in-stent restenosis, 2 non-stent restenosis, 1 mixed lesion) (pâ¯=â¯0.0249). There was no difference in the median treated length between the adjunctive PTA (15â¯cm) and DCB (10â¯cm) groups (pâ¯=â¯0.0530). The estimated freedom from TLR (fTLR) was significantly higher with atherectomy and adjunctive DCB compared to atherectomy with adjunctive PTA at 12â¯months (94.7% vs 68.0%, pâ¯=â¯0.002) and 16â¯months (94.4% vs 54%; pâ¯=â¯0.002). CONCLUSIONS: In a single center cohort of JA reflecting real-world practice, JA with DCB had a superior TLR rate up to 16-month follow-up when compared to JA with PTA in treating all comers FP arterial disease.

Endovascular intervention is a mainstay treatment of peripheral artery disease (PAD) in addition to aggressive risk factor modification and exercise programs in patients with favorable anatomy or in those who are considered too high risk for surgical intervention. Treatment with percutaneous transluminal angioplasty (PTA) and bare metal stents (BMS) has been limited by high rates of in-stent restenosis (ISR) requiring repeat revascularization. Drug-eluting stents (DES), developed and designed to reduce ISR, offer a promising solution to the current challenges in endovascular management of PAD. Several randomized clinical trials have shown improved short- and mid-term outcomes with DES as compared with both PTA and BMS. Herein we provide an up-to-date review of the current literature on DES use in PAD.

BACKGROUND: It is unclear whether patients on oral anticoagulants (OAC) undergoing a procedure using common femoral artery access have higher adverse events when compared to patients who are not anticoagulated at the time of the procedure. METHODS: We retrospectively reviewed data from consecutive patients who underwent a cardiac procedure at a tertiary medical center. Patients were considered (group A) fully or partially anticoagulated if they had an international normalized ratio (INR) ≥1.6 on the day of the procedure or were on warfarin or new OAC within 48 h and 24 h of the procedure, respectively. The nonanticoagulated group (group B) had an INR <1.6 or had stopped their warfarin and new OAC >48 h and >24 h preprocedure, respectively. The index primary end point of the study was defined as the composite end point of major bleeding, vascular complications, or cardiovascular-related death during index hospitalization. The 30-day primary end point was defined as the occurrence of the index primary end point and up to 30 days postprocedure. RESULTS: A total of 779 patients were included in this study. Of these patients, 27 (3.5%) patients were in group A. The index primary end point was met in 11/779 (1.4%) patients. The 30-day primary composite end point was met in 18/779 (2.3%) patients. There was no difference in the primary end point at index between group A (1/27 [3.7%]) and group B (10/752 [1.3%]; P=0.3155) and no difference in the 30-day primary composite end point between group A (2/27 [7.4%]) and group B (16/752 [2.1%]; P=0.1313). Multivariable analysis showed that a low creatinine clearance (odds ratio [OR] =0.56; P=0.0200) and underweight patients (<60 kg; OR =3.94; P=0.0300) were independent predictors of the 30-day primary composite end point but not oral anticoagulation (P=0.1500). CONCLUSION: Patients on OAC did not have higher 30-day major adverse events than those who were not anticoagulated at index procedure.
RESUMO
Chronic total occlusions (CTOs) are seen in 30%-40% of symptomatic superficial femoral artery (SFA) disease. Despite advances in revascularization techniques, 10%-20% of these occlusions cannot be crossed. We report 1 case and review the literature on transcollateral retrograde crossing of the SFA from the profunda femoris. The procedural steps and devices (wires and crossing catheters) utilized by various operators are outlined. Based on an overview of current cases in the literature (19 cases, 21 CTOs), success rate was 95.2% with no complications reported. We conclude that transcollateral recanalization of chronically occluded SFA appears to be a viable technique when antegrade access is not feasible.

Double inferior vena cava (DIVC) is present in 0.2%-3.0% of the general population. Its presence can be detected by computed tomographic angiography or magnetic resonance imaging. Identifying the presence of DIVC is important to define its relationship with the renal vein, its size when IVC filters are planned, the location of the left renal vein in relationship to the aorta, and for planning of IVC filter placement in the setting of deep vein thrombosis and pulmonary embolism. Finally, this entity should not be mistaken for lymphadenopathy and its course should be well understood before abdominal and pelvic/retroperitoneal surgical interventions.
